Paul Bolle 9b91bd81fa ARM: OMAP2+: remove OMAP_PACKAGE_ZAC and OMAP_PACKAGE_ZAF
The Kconfig symbols OMAP_PACKAGE_ZAC and OMAP_PACKAGE_ZAF were added in
v2.6.36. They have never been used. Setting them has no effect. These
symbols can safely be removed.

Rajendra Nayak 5b5c013591 ARM: OMAP2+: AM43x: Use gptimer as clocksource
The SyncTimer in AM43x is clocked using the following two sources:
1) An inaccuarte 32k clock (CLK_32KHZ) derived from PER DPLL, causing system
   time to go slowly (~10% deviation).
2) external 32KHz RTC clock, which may not always be available on board like
   in the case of ePOS EVM

Use gptimer as clocksource instead, as is done in the case of AM335x
(which does not have a SyncTimer). With this, system time keeping works
accurately.

Dmitry Lifshitz b62d91e5e1 ARM: OMAP2+: make reset pulse for sbc-t3x usb hubs
sbc-t3x boards features two external USB ports on SB-T35 baseboard.
The baseboardi USB hub reset signal should be de-asserted to make
those ports functional.

sbc-t3517 features additional (assembled on CoM) USB hub which also
requires reset signal handling.

Add quirks code to handle proper reset pulse signal.

Dave Gerlach f67f04ba27 ARM: OMAP2+: clockdomain: Reintroduce SW_SLEEP Support
Since commit 65aa94b204 (ARM: OMAP4: clockdomain/CM code: Update supported
transition modes), on OMAP4, all CLKDMs support HW_AUTO so this is used
instead of SW_SLEEP for the idling of clockdomains. However, additional
SoCs now leverage the OMAP4 clockdomain code so update it to use SW_SLEEP
if the clockdomain data specifies that the CLKDM has the
CLKDM_CAN_FORCE_SLEEP flag set rather than using HW_AUTO for both cases.

Without this patch, clockdomain handling is broken on AM43xx and no
clockdomains are actually being put into idle on this platform. Any
attempt to idle them results in the HW_AUTO value (0x3) being written
to them with no apparent effect.

Merge tag 'for-v3.14-rc/omap-fixes-a' of git://git.kernel.org/pub/scm/linux/kernel/git/pjw/omap-pending into omap-for-v3.14/fixes

Several OMAP clock/PM/device data fixes for v3.14-rc.  There's an OMAP5
reboot fix in there, plus a clock fix for rate computations involving
x2 multipliers.

Basic build, boot, and PM test logs are available here:

http://www.pwsan.com/omap/testlogs/prcm-fixes-a-v3.14-rc/20140219131753/

Note that most full-chip PM is broken since the v3.14 merge; it's
not caused by this series.

Tomi Valkeinen 994c41ee0a ARM: OMAP2+: clock: fix clkoutx2 with CLK_SET_RATE_PARENT
If CLK_SET_RATE_PARENT is set for a clkoutx2 clock, calling
clk_set_rate() on the clock "skips" the x2 multiplier as there are no
set_rate and round_rate functions defined for the clkoutx2.

This results in getting double the requested clock rates, breaking the
display on omap3430 based devices. This got broken when
d0f58bd3bb and related patches were merged
for v3.14, as omapdss driver now relies more on the clk-framework and
CLK_SET_RATE_PARENT.

This patch implements set_rate and round_rate for clkoutx2.

Tested on OMAP3430, OMAP3630, OMAP4460.

Commit 313a76e (ARM: OMAP2+: hwmod: Fix SOFTRESET logic) introduced
softreset bit cleaning right after set one. It is caused L3 error for
OMAP4 ISS because ISS register write occurs when ISS reset process is in
progress. Avoid this situation by cleaning softreset bit later, when reset

Fixes: commit 75d3625e0e
       ARM: OMAP2+: gpmc: add DT bindings for OneNAND

OMAP SoC(s) depend on GPMC controller driver to parse GPMC DT child nodes and
register them platform_device for ONENAND driver to probe later. However this does
not happen if generic MTD_ONENAND framework is built as module (CONFIG_MTD_ONENAND=m).

Therefore, when MTD/ONENAND and MTD/ONENAND/OMAP2 modules are loaded, they are unable
to find any matching platform_device and remain un-binded. This causes on board
ONENAND flash to remain un-detected.

is same as the hardware irq number only when the parent irqchip

the virtual irqs are allocated dynamically and wakeup gen code
cannot rely on these numbers to access the irq registers. Instead
use the hwirq element of the irq_data which represent the physical

   nobody cares enough to fix it, it would be removed on a couple Kernel
   releases
 - the sn9c102 driver was moved to staging.  This driver was replaced by
   gspca, and disabled on some distros, as almost all devices are known
   to work properly with gspca.  It should be removed from kernel on a
   couple Kernel releases

Linus Torvalds d30492adea The second half of the clock framework pull requeust for 3.14 is
dominated by platform support for Qualcomm's MSM SoCs, DT binding
 updates for TI's OMAP-ish processors and additional support for Samsung
 chips. Additionally there are other smaller clock driver changes and
 several last minute fixes. This pull request also includes the HiSilicon
 support that depends on the already-merged arm-soc pull request.

Linus Torvalds 903a9f77d1 ARM: SoC board updates for 3.14
This branch is reducing in size for every release since most board-related
 changes have started happening in devicetrees now. Still, we have some things
 going on here.
 
 * Renesas platforms are still adding a bit more legacy device support, something
   that should trail off shortly as they move to full DT.
 * We group most defconfig updates into this branch out of old habits
 * Removal of legacy OMAP2 platforms over to DT continues, and a handful of old
   code is being removed here.

Linus Torvalds 93abdb7785 ARM: SoC non-critical fixes for 3.14
As usual, we have a batch of fixes that weren't considered significant
 enough to warrant going into the later -rcs for previous release, so
 they are queued up on this branch.
 
 A handful of these are for various DT fixups for Samsung platforms,
 and a handful of other minor things.
 
 There are also a couple of stable-marked patches for mvebu -- they came in
 quite late and we decided to keep them deferred until the first -stable
 release to get more coverage instead of squeezing them into 3.13.

Santosh Shilimkar b6cb5bab26 arch/arm/mach-omap2/omap_hwmod.c: use memblock apis for early memory allocations
Switch to memblock interfaces for early memory allocator instead of
bootmem allocator.  No functional change in beahvior than what it is in
current code from bootmem users points of view.

Archs already converted to NO_BOOTMEM now directly use memblock
interfaces instead of bootmem wrappers build on top of memblock.  And
the archs which still uses bootmem, these new apis just fallback to
exiting bootmem APIs.

Kexec disables outer cache before jumping to reboot code, but it doesn't
flush it explicitly. Flush is done implicitly inside of l2x0_disable().
But some SoC's override default .disable handler and don't flush cache.
This may lead to a corrupted memory during Kexec reboot on these
platforms.

This patch adds cache flush inside of OMAP4 and Highbank outer_cache.disable()
handlers to make it consistent with default l2x0_disable().

Fix the issue by registering the DPI LCD panel only after the twl4030

http://compulab.co.il/products/sbcs/sbc-t3517/
http://compulab.co.il/products/sbcs/sbc-t3730/

So let's add a common omap3-sb-t35.dtsi and then separate SoC
specific omap3-sbc-t3730.dts, omap3-sbc-t3530.dts and
omap3-sbc-t3517.dts.

I've tested this with SBC-T3730 as that's the only one I have.
At least serial, both Ethernet controllers, MMC, and wl12xx WLAN
work.

Note that WLAN seems to be different for SBC-T3530. And SBC-T3517
may need some changes for the EMAC Ethernet if that's used
instead of the smsc911x.

So this information belongs to the platform data and should not be hardcoded
in the subdevice driver.

Commit e30b06f4d5 (ARM: OMAP2+: Remove
legacy mux code for display.c) removed non-DT DSI and HDMI pinmuxing.
However, DSI pinmuxing is still needed, and removing that caused DSI
displays not to work.

This reverts the DSI parts of the commit.

Nishanth Menon f5c33b070d ARM: OMAP2+: omap_device: add fail hook for runtime_pm when bad data is detected
Due to the cross dependencies between hwmod for automanaged device
information for OMAP and dts node definitions, we can run into scenarios
where the dts node is defined, however it's hwmod entry is yet to be
added. In these cases:
a) omap_device does not register a pm_domain (since it cannot find
   hwmod entry).
b) driver does not know about (a), does a pm_runtime_get_sync which
   never fails
c) It then tries to do some operation on the device (such as read the
  revision register (as part of probe) without clock or adequate OMAP
  generic PM operation performed for enabling the module.

This causes a crash such as that reported in:
https://bugzilla.kernel.org/show_bug.cgi?id=66441

When 'ti,hwmod' is provided in dt node, it is expected that the device
will not function without the OMAP's power automanagement. Hence, when
we hit a fail condition (due to hwmod entries not present or other
similar scenario), fail at pm_domain level due to lack of data, provide
enough information for it to be fixed, however, it allows for the driver
to take appropriate measures to prevent crash.

Roger Quadros 313a76ee11 ARM: OMAP2+: hwmod: Fix SOFTRESET logic
In _ocp_softreset(), after _set_softreset() + write_sysconfig(),
the hwmod's sysc_cache will always contain SOFTRESET bit set
so all further writes to sysconfig using this cache will initiate
a repeated SOFTRESET e.g. enable_sysc(). This is true for OMAP3 like
platforms that have RESET_DONE status in the SYSSTATUS register and
so the the SOFTRESET bit in SYSCONFIG is not automatically cleared.
It is not a problem for OMAP4 like platforms that indicate RESET
completion by clearing the SOFTRESET bit in the SYSCONFIG register.

This repeated SOFTRESET is undesired and was the root cause of
USB host issues on OMAP3 platforms when hwmod was allowed to do the
SOFTRESET for the USB Host module.

To fix this we clear the SOFTRESET bit and update the sysconfig
register + sysc_cache using write_sysconfig().

Tony Lindgren dad12d1138 ARM: OMAP2+: Add support for legacy auxdata for twl
As we currently need to support a mix of legacy platform data and
device tree intialized data, let's make sure things keep working
for the TWL GPIOs.

Mostly the issue is caused by the fact that DSS does not yet have
device tree bindings, so we need to rely on the TWL GPIO callback
for setting up things like LCD backlight for some boards.

As of_platform_populate() for the TWL GPIO is called by twl-core
after the I2C bus has been initialized, we cannot pass the auxdata
table from the board init code to twl-core like we used to with
just legacy platform data.

So let's use the omap_device bus hook to patch in the platform
data for TWL GPIO until we have sorted out the issues with the
TWL GPIOs and device tree bindings.

The other option was be to initialize twl core using legacy
platform data, which seems like a step backwards as we're moving
to device tree only initialization.  And we really don't want to
add custom configuration functions to the TWL GPIO driver either
for this.

Tony Lindgren 5e863c5610 ARM: OMAP2+: Fix overwriting hwmod data with data from device tree
We have some device tree properties where the ti,hwmod have multiple
values:

am33xx.dtsi:	ti,hwmods = "tpcc", "tptc0", "tptc1", "tptc2";
am4372.dtsi:	ti,hwmods = "tpcc", "tptc0", "tptc1", "tptc2";
dra7.dtsi:	ti,hwmods = "l3_main_1", "l3_main_2";
omap3.dtsi:	ti,hwmods = "mcbsp2", "mcbsp2_sidetone";
omap3.dtsi:	ti,hwmods = "mcbsp3", "mcbsp3_sidetone";
omap4.dtsi:	ti,hwmods = "l3_main_1", "l3_main_2", "l3_main_3";
omap5.dtsi:	ti,hwmods = "l3_main_1", "l3_main_2", "l3_main_3";

That's not correct way of doing things in this case because these are
separate devices with their own address space, interrupts, SYSCONFIG
registers and can set their PM states independently.

So they should all be fixed up to be separate devices in the .dts files.

We also have the related data removed for at least omap4 in commit
3b9b10151c (ARM: OMAP4: hwmod data: Clean up the data file), so
that data is wrongly initialized as null data.

So we need to fix two bugs:

1. We are only checking the first entry of the ti,hwmods property

   This means that we're only initializing the first hwmods entry
   instead of the ones listed in the ti,hwmods property.

2. We are only checking the child nodes, not the nodes themselves

   This means that anything listed at OCP level is currently just
   ignored and unitialized and at least the omap4 case, with the
   legacy data missing from the hwmod.

Fix both of the issues by using an index to the ti,hwmods property
and changing the hwmod lookup function to also check the current node
for ti,hwmods property instead of just the children.

While at it, let's also add some warnings for the bad data so it's
easier to fix.

From Tony Lindgren:

Some omap related fixes that have come up with people moving to device
tree only based booting for omap2+.

The series contains a handful of fixes for the igep boards as they were
one of the first omap3 boards to jump over completely to device tree
based booting. So these can be considered regressions compared to
booting igep in legacy mode with board files in v3.12.

Also included are few other device tree vs legacy booting regressions:

- yet more missing omap3 .dtsi entries that have showed up booting
  various boards with device tree only

- n900 eMMC device tree fix

- fixes for beagle USB EHCI

- two fixes to make omap2420 MMC work

As we're moving omap2+ to be device tree only for v3.14, I'd like to
have v3.13 work equally well for legacy based booting and device tree
based booting. So there will be likely few more device tree related
booting patches trickling in.

This series also includes a regression fix for the omap timer posted
mode that may wrongly stay on from the bootloader for some SoCs.

Commit f2bf0e72d0 (ARM: OMAP2+: Add minimal 8250 support

a similar issue as 8250 with the bootloader timings.

And let's fix the 8250 naming, we should use the device type as
the name like uart instead of 8250 for zoom dts file.

Nishanth Menon 3522bf7bfa ARM: OMAP2+: omap_device: maintain sane runtime pm status around suspend/resume
OMAP device hooks around suspend|resume_noirq ensures that hwmod
devices are forced to idle using omap_device_idle/enable as part of
the last stage of suspend activity.

For a device such as i2c who uses autosuspend, it is possible to enter
the suspend path with dev->power.runtime_status = RPM_ACTIVE.

As part of the suspend flow, the generic runtime logic would increment
it's dev->power.disable_depth to 1. This should prevent further
pm_runtime_get_sync from succeeding once the runtime_status has been
set to RPM_SUSPENDED.

Now, as part of the suspend_noirq handler in omap_device, we force the
following: if the device status is !suspended, we force the device
to idle using omap_device_idle (clocks are cut etc..). This ensures
that from a hardware perspective, the device is "suspended". However,
runtime_status is left to be active.

*if* an operation is attempted after this point to
pm_runtime_get_sync, runtime framework depends on runtime_status to
indicate accurately the device status, and since it sees it to be
ACTIVE, it assumes the module is functional and returns a non-error
value. As a result the user will see pm_runtime_get succeed, however a
register access will crash due to the lack of clocks.

To prevent this from happening, we should ensure that runtime_status
exactly indicates the device status. As a result of this change
any further calls to pm_runtime_get* would return -EACCES (since
disable_depth is 1). On resume, we restore the clocks and runtime
status exactly as we suspended with. These operations are not expected
to fail as we update the states after the core runtime framework has
suspended itself and restore before the core runtime framework has
resumed.

    fields; use correct interfaces)
  * Fix BUG() for new odd-sized NAND, which report non-power-of-2 dimensions via
    ONFI
  * Miscellaneous driver fixes (SPI NOR flash; BCM47xx NAND flash; etc.)
  * Improve differentiation between SLC and MLC NAND -- this clarifies an ABI
    issue regarding the MTD "type" (in sysfs and in ioctl(MEMGETINFO)), where
    the MTD_MLCNANDFLASH type was present but inconsistently used
  * Extend GPMI NAND to support multi-chip-select NAND for some platforms
  * Many improvements to the OMAP2/3 NAND driver, including an expanded DT
    binding to bring us closer to mainline support for some OMAP systems
  * Fix a deadlock in the error path of the Atmel NAND driver probe
  * Correct the error codes from MTD mmap() to conform to POSIX and the Linux
    Programmer's Manual. This is an acknowledged change in the MTD ABI, but I
    can't imagine somebody relying on the non-standard -ENOSYS error code
    specifically. Am I just being unimaginative? :)
  * Fix a few important GPMI NAND bugs (one regression from 3.12 and one
    long-standing race condition)

Linus Torvalds f9efbce633 ARM: SoC DT updates for 3.13
Most of this branch consists of updates, additions and general churn of
 the device tree source files in the kernel (arch/arm/boot/dts). Besides
 that, there are a few things to point out:
 
 - Lots of platform conversion on OMAP2+, with removal of old board files
   for various platforms.
 - Final conversion of a bunch of ux500 (ST-Ericsson) platforms as well
 - Some updates to pinctrl and other subsystems. Most of these are for
   DT-enablement of the various platforms and acks have been collected.

Linus Torvalds d5aabbcaee ARM: SoC board updates for 3.13
Board-related updates. This branch is getting smaller and smaller, which is
 the whole idea so that's reassuring.
 
 Right now by far most of the code is related to shmobile updates, and
 they are now switching over to removal of board code and migration to
 multiplatform, so we'll see their board code base shrink in the near
 future too, I hope.
 
 In addition to that is some defconfig updates, some display updates for OMAP
 and a bit of new board support for Rockchip boards.

Linus Torvalds 21604cdcdc ARM: SoC cleanups for 3.13
This branch contains code cleanups, moves and removals for 3.13.
 
 Qualcomm msm targets had a bunch of code removal for legacy non-DT
 platforms. Nomadik saw more device tree conversions and cleanup of old
 code. Tegra has some code refactoring, etc.
 
 One longish patch series from Sebastian Hasselbarth changes the init_time
 hooks and tries to use a generic implementation for most platforms,
 since they were all doing more or less the same things.
 
 Finally the "shark" platform is removed in this release. It's been
 abandoned for a while and nobody seems to care enough to keep it
 around. If someone comes along and wants to resurrect it, the removal
 can easily be reverted and code brought back.
 
 Beyond this, mostly a bunch of removals of stale content across the
 board, etc.

Pekon Gupta c66d039197 mtd: nand: omap: combine different flavours of 1-bit hamming ecc schemes
OMAP NAND driver currently supports multiple flavours of 1-bit Hamming
ecc-scheme, like:
- OMAP_ECC_HAMMING_CODE_DEFAULT
	1-bit hamming ecc code using software library
- OMAP_ECC_HAMMING_CODE_HW
	1-bit hamming ecc-code using GPMC h/w engine
- OMAP_ECC_HAMMING_CODE_HW_ROMCODE
	1-bit hamming ecc-code using GPMC h/w engin with ecc-layout compatible
	to ROM code.

This patch combines above multiple ecc-schemes into single implementation:
- OMAP_ECC_HAM1_CODE_HW
	1-bit hamming ecc-code using GPMC h/w engine with ROM-code compatible
	ecc-layout.

Pekon Gupta ac65caf514 ARM: OMAP2+: cleaned-up DT support of various ECC schemes
OMAP NAND driver support multiple ECC scheme, which can used in different
flavours, depending on in-build Hardware engines present on SoC.

This patch updates following in DT bindings related to sectionion of ecc-schemes
- ti,elm-id: replaces elm_id (maintains backward compatibility)
- ti,nand-ecc-opts: selection of h/w or s/w implementation of an ecc-scheme
	depends on ti,elm-id. (supported values ham1, bch4, and bch8)
- maintain backward compatibility to deprecated DT bindings (sw, hw, hw-romcode)

Below table shows different flavours of ecc-schemes supported by OMAP devices
+---------------------------------------+---------------+---------------+
| ECC scheme                            |ECC calculation|Error detection|
+---------------------------------------+---------------+---------------+
|OMAP_ECC_HAM1_CODE_HW                  |H/W (GPMC)     |S/W            |

To optimize footprint of omap2-nand driver, selection of some ECC schemes
also require enabling following Kconfigs, in addition to setting appropriate
DT bindings
- Kconfig:CONFIG_MTD_NAND_ECC_BCH        error detection done in software
- Kconfig:CONFIG_MTD_NAND_OMAP_BCH       error detection done by h/w engine

Afzal Mohammed 6246cd06d8 ARM: OMAP2+: wakeupgen: AM43x adaptation
AM43x has 224 interrupts and 7 banks, make it as maximum values. Keep
default values as earlier, if am43x is detected, update interrupts and
banks accordingly.

Also AM43x has only one cpu, ensure that clearing bitmask at wakeupgen
is done only for the single existing cpu, existing code assumes that
there are two cpu's.

If bitmask is cleared in wakeupgen for the nonexistent second cpu,
an imprecise abort happens as soon as Kernel switches to user space.

Kevin Hilman abcba009e5 Changes needed for am43xx for the hwmod data.
This will be the last new set of hwmod data for any SoC

 Queued by Paul Walmsley <paul@pwsan.com>:

 Under normal circumstances, these patches would not be merged.
 The hwmod and PRCM data should be moved out either to DT data or

 of diff by dynamically rewriting static data at runtime, which is
 a bad practice - it causes future maintenance headaches.
 However, after speaking with my upstream, it sounds like it's
 better to merge these patches in their current state, due to long
 term considerations.
 
 Basic test logs are here:

 Due to the lack of an AM43xx board and any available public
 documentation, it's impossible for me to review or test that
 platform in any meaningful way.  But at least the tests above
 verify that the patches don't affect existing platforms -
 particularly AM33xx.

AM43x additional ones added here are,
1. synctimer
2. timer8-11
3. ehrpwm3-5
4. spi2-4
5. gpio4-5

AM43x pruss interconnect which is different as compared to AM335x, has
been taken care.

And register offsets for same hwmod's shared with AM335x is different,
AM43x register offsets are updated appropriately.

ocp clock of those in l4_wkup is fed from "sys_clkin_ck" instead of
"dpll_core_m4_div2_ck", so "ocpif" for those in AM43x l4_wkup has been
added seperately.

hwmod's has been added for those that have main clock (wkup_m3, control,
gpio0) and clock domain (l4_hs) different from AM335x. debugss and
adc_tsc that have different clocks and clockdomains repectively has not
been added due to the reasons mentioned below.

AM43x also has IP's like qspi, hdq1w, vpfe, des, rng, usb, dss, debugss,
adc_tsc. These are not handled here due to both/either of following
reasons,
1. To avoid churn; most of them don't have DT bindings, which would
   necessitate adding address space in hwmod, which any way would have
   to be removed once DT bindings happen with driver support.
2. patches would come in from sources other than the author

Afzal Mohammed 26649467ad ARM: OMAP2+: hwmod: AM335x/AM43x: move common data
AM335x and AM43x have most of the IP's and interconnect's similar.
Instead of adding redundant hwmod data, move interconnects and hwmod
similar between AM335x and AM43x to a common location. This helps in
reuse on AM43x.

AM335x interconnects that has difference and not present in AM43x are
not moved. ocp clock of those in l4_wkup is fed from a different source
for AM43x. Also pruss interconnect is different.

AM335x hwmod's that has difference other than prcm register offsets
(difference is in clocks of wkup_m3, control, gpio0, debugss and clock
domain of l4_hs, adc_tsc as compared to AM43x) and those that are not
present in AM43x are not moved.

The realtime counter called master counter, produces the count
used by the private timer peripherals in the MPU_CLUSTER. The
CNTFRQ per cpu register is used to denote the frequency of the counter.
Currently the frequency value is passed from the

secure rom code. Setting this register helps in propagating the right
frequency value across OSes.

way can be seen from below.

Suman Anna 6423d6df14 ARM: OMAP2+: hwmod: check for module address space during init
The hwmod init sequence involves initializing and idling all the
hwmods during bootup. If a module class has sysconfig, the init
sequence utilizes the module register base for performing any
sysc configuration.

The module address space is being removed from hwmod database and
retrieved from the <reg> property of the corresponding DT node.
If a hwmod does not have its corresponding DT node defined and the
memory address space is not defined in the corresponding
omap_hwmod_ocp_if, then the module register target address space
would be NULL and any sysc programming would result in a NULL
pointer dereference and a kernel boot hang.

Handle this scenario by checking for a valid module address space
during the _init of each hwmod, and leaving it in the registered
state if no module register address base is defined in either of
the hwmod data or the DT data.

commit 7ce236fcd6 that sets IBE bit is a noop.

In order to have workaround for ARM errata 430973 from non-secure world on

This patch adds RX-51 specific secure support code and sets IBE bit in ACTLR
during board init code for ARM errata 430973 workaround.

Note that new function rx51_secure_dispatcher() differs from existing
omap_secure_dispatcher(). It calling omap_smc3() and param[0] is nargs+1.

ARM errata 430973 workaround is needed for thumb-2 ISA compiled userspace

Linus Walleij de26804b60 ARM: OMAP2+: throw the die id into the entropy pool
At least eight bytes of this number are totally unique for the device
it seems, so this is a perfect candidate for feeding the entropy
pool. One byte more or less of constants does not matter so feed in
the entire OID struct.

This fixes the issue of similar devices initializing to the
same state initially.

Further registers could be added too, such as OMAP4
CONTROL_STD_FUSE_OPP* and CONTROL_DPLL_NWELL_TRIM* registers,
but those vary based on the SoC generation.

Aaro Koskinen 1dc1c33879 ARM: OMAP2: gpmc-onenand: fix sync mode setup with DT
With DT-based boot, the GPMC OneNAND sync mode setup does not work
correctly. During the async mode setup, sync flags gets incorrectly
set in the onenand_async data and the system crashes during the async
setup. Also, the sync mode never gets set in gpmc_onenand_data->flags, so
even without the crash, the actual sync mode setup would never be called.

The patch fixes this by adjusting the gpmc_onenand_data->flags when the
data is read from the DT. Also while doing this we force the onenand_async
to be always async.

The patch enables to use the following DTS chunk (that should correspond
the arch/arm/mach-omap2/board-rm680.c board file setup) with Nokia N950,
which currently crashes with 3.12-rc1. The crash output can be also
found below.

It is supposed that sar_base is initialized in irq_save_context, which
is called on CPU_CLUSTER_PM_ENTER notification. If this notification
has been missed and CPU_CLUSTER_PM_EXIT is received sar_base is NULL.

Fix it by calling CPU_CLUSTER_PM_{ENTER,EXIT} under the same condition.

Looks like we still have the legacy clock alias name for
omap4 GPMC (General Purpose Memory Controller), so let's
fix it for the device tree naming. There's no need to keep
the legacy naming as omap4 is DT only nowadays.

Without this fix we get the following error while booting:

Linus Torvalds b4b50fd78b ARM: SoC platform changes for 3.12
This branch contains mostly additions and changes to platform enablement
 and SoC-level drivers. Since there's sometimes a dependency on device-tree
 changes, there's also a fair amount of those in this branch.
 
 Pieces worth mentioning are:
 
 - Mbus driver for Marvell platforms, allowing kernel configuration
   and resource allocation of on-chip peripherals.
 - Enablement of the mbus infrastructure from Marvell PCI-e drivers.
 - Preparation of MSI support for Marvell platforms.
 - Addition of new PCI-e host controller driver for Tegra platforms
 - Some churn caused by sharing of macro names between i.MX 6Q and 6DL
   platforms in the device tree sources and header files.
 - Various suspend/PM updates for Tegra, including LP1 support.
 - Versatile Express support for MCPM, part of big little support.
 - Allwinner platform support for A20 and A31 SoCs (dual and quad Cortex-A7)
 - OMAP2+ support for DRA7, a new Cortex-A15-based SoC.
 
 The code that touches other architectures are patches moving
 MSI arch-specific functions over to weak symbols and removal of
 ARCH_SUPPORTS_MSI, acked by PCI maintainers.

Linus Torvalds 8e73e367f7 ARM: SoC cleanups for 3.12
This branch contains code cleanups, moves and removals for 3.12.
 
 There's a large number of various cleanups, and a nice net removal of
 13500 lines of code.
 
 Highlights worth mentioning are:
 
 - A series of patches from Stephen Boyd removing the ARM local timer API.
 - Move of Qualcomm MSM IOMMU code to drivers/iommu.
 - Samsung PWM driver cleanups from Tomasz Figa, removing legacy PWM driver
   and switching over to the drivers/pwm one.
 - Removal of some unusued auto-generated headers for OMAP2+ (PRM/CM).
 
 There's also a move of a header file out of include/linux/i2c/ to
 platform_data, where it really belongs. It touches mostly ARM platform
 code for include changes so we took it through our tree.

Linus Torvalds d2f3e9eb7c ARM: SoC low-priority fixes for 3.12
This branch contains a handful of fixes for various platforms that
 weren't serious enough to be included in late 3.11-rc releases. Most of
 them are for minor cleanups and cosmetic fixes.
 
 There's also a bit of code removal here, one board file removal for
 clps711x, and removal of some legacy device creation on OMAP2+.

Tomi Valkeinen 35f5df6fd8 OMAPDSS: fix DPI and SDI device ids
The DPI and SDI platform devices are currently created with the ID of
-1. The ID doesn't currently affect anything.

However, we have added regulator supply entries for "omapdss_dpi.0" and
"omapdss_sdi.0" to the board files, although these supply entries are
not yet used. As the ID used for the devices is -1, these regulator
supply entries will not work.

To fix the issue, assign ID of 0 to the devices. In the future there may
be more than one DPI or SDI output, so it makes sense to have a proper
ID for them.

Note that the LCD add-on boards for lcd43 and lcd35 use the same GPIOs

the same time.

DT will handle this correctly, i.e. the DT data will contain the panel
device only for the add-on board that is attached. However, for the
board file we need a hackish solution: We parse the kernel boot command
line, and see whether lcd43 or lcd35 is set as a default display, and
add the given one. Or, if neither is given, default to lcd43.

Managing that kind of board specific setup is not simple without board
file callbacks. As only some 4430SDP boards actually have the PicoDLP
installed, and 4430SDP boards are not that common in the first place,
let's remove PicoDLP data from the board file.

Rajendra Nayak eeb6603fdd ARM: OMAP4: clock: Lock PLLs in the right sequence
On OMAP4 we have clk_set_rate()s being done for a few
DPLL clock nodes, as part of the clock init code, since
the bootloaders no longer locks these DPLLs.

So we have a clk_set_rate() done for a ABE DPLL node (which
inturn locks it) followed by a clk_set_rate() for the USB DPLL.

With USB DPLL being in bypass, we have this parent->child
relationship thats formed while the clocks get registered.

dpll_abe_ck
    |
    V
dpll_abe_x2_ck
    |
    V
dpll_abe_m3x2_ck
    |
    V
usb_hs_clk_div_ck
    |
    V
dpll_usb_ck

This is because usb_hs_clk_div_ck is bypass clock for dpll_usb_ck.

So with this parent->child relationship in place, a clk_set_rate()
on ABE DPLL results eventually in a clk_set_rate() call on USB DPLL,
because CCF does a clk_change_rate() (as part of clk_set_rate()) on
all downstream clocks resulting from a rate change on the top clock.

So its important that we lock USB DPLL before we lock ABE DPLL.
Without which we see these error logs at boot.
[These error logs will not be seen if using a bootloader that locks
USB DPLL]

Jon Hunter 127500ccb7 ARM: OMAP2+: Only write the sysconfig on idle when necessary
Currently, whenever we idle a device _idle_sysc() is called and writes to the
devices SYSCONFIG register to set the idle mode. A lot devices are using the
smart-idle mode and so the write to the SYSCONFIG register is programming the
same value that is already stored in the register.

Writes to the devices SYSCONFIG register can be slow, for example, writing to
the DMTIMER SYSCONFIG register takes 3 interface clock cycles and 3 functional
clock cycles. If the DMTIMER is using the slow 32kHz functional clock this can
take ~100us.

Furthermore, during boot on an OMAP4430 panda board, I see that there are 100
calls to _idle_sysc(), however, only 3 out of the 100 calls actually write
the SYSCONFIG register with a new value.

Therefore, to avoid unnecessary writes to device SYSCONFIG registers when
idling the device, only write the value if the value has changed. It should be
safe to do this on idle as the context of the register will never be lost while
the device is active.

Verified that suspend, CORE off and retention states are working with this
change on OMAP3430 Beagle board.

This header has traditionally been autogenerated on OMAP4+ devices but
the autogenerated contents are largely (95%) unused and hence to reduce
unsued data in the kernel this header has been cut down (from the autogen
output) to whatever is currently needed. This is done by running a cleanup
script on top of the existing autogen script.

Linus Torvalds 1f8b76656b ARM: SoC fixes for 3.11-rc
A handful of fixes for 3.11 are still trickling in. These are:
 - A couple of fixes for older OMAP platforms
 - Another few fixes for at91 (lateish due to European summer vacations)
 - A late-found problem with USB on Tegra, fix is to keep VBUS regulator
   on at all times
 - One fix for Exynos 5440 dealing with CPU detection
 - One MAINTAINERS update

'gpmc_irq_start' is mostly used as 'int', and for a variable, do not

Chen Baozi 42c604ba7c ARM: OMAP2+: fix wrong address when loading PRM_FRAC_INCREMENTOR_DENUMERATOR_RELOAD
The denominator should be load from INCREMENTOR_DENUMERATOR_RELOAD_OFFSET
rather than INCREMENTER_NUMERATOR_OFFSET.

This is more likely a typo, since INCREMENTER_DENUMERATOR_RELOAD[23:17] is
reserved. It seems that it won't make much trouble without this fix, because
the useful [11:0] bits are mask and set the right value. Anyway, reading
from a right address is better choice.

Peripheral-only mode got broken in v3.11-rc1 because of unknown reasons.
Change the mode to OTG, in practice that should work equally well even
when/if the regression gets fixed.

Note that the peripheral-only regression is a separate patch, this change
is still correct as the role is handled by hardware.

Commit b7e2e75a8c ("usb: gadget: drop unused USB_GADGET_MUSB_HDRC")
dropped a config symbol that was unused by the musb core, but it turns
out that board support code still had references to it.

As the core now handles both dual role and host-only modes, we can just
pass MUSB_OTG as mode from board files.
