Linus Torvalds 0a9e0acddb ARM: SoC non-critical bug fixes for 3.19
These are bug fixes for harmless problems that were not important
 enough to get fixed in 3.19. This contains updates to the MAINTAINERS
 file, in particular:
 
 - Ben Dooks stepped down as Samsung co-maintainer (thanks Ben for
   long years of maintaining this). Kukjin Kim, who has been
   doing the work de-facto by himself recently is now the
   only maintainer.
 - Liviu, Sudeep and Lorenzo from ARM now officially maintain the
   Versatile Express platform, which was orphaned (thanks for
 - Gregory Fong and Florian Fainelli help out on the Broadcom BCM7XXX
   platform
 - Ray Jui and Scott Branden are the future maintainers for the
   newly merged Broadcom Cygnus platform. Welcome!
 
 In terms of actual fixes, we have the usual set of OMAP bug fixes,
 which Tony Lindgren separates out well from the other OMAP changes,
 one really ep93xx regression fix against 3.11 that didn't make it for
 3.18, a few GIC changes from Marc Zyngier as a preparation for
 later rework (the current code is wrong in a harmless way), on
 Tegra regression and one samsung spelling fix.

Arnd Bergmann 1306b20daa We can finally move the GPMC code to live in drivers/memory for
further clean up work.
 
 Note that we still have dependencies to the legacy booting for
 omap3 board-*.c files for setting up the board specific memory
 timings. For that we need the timing related things still exposed
 in include/linux/omap-gpmc.h. This will all become private data
 to the GPMC driver once the legacy booting support can be dropped.

Tony Lindgren a861280938 ARM: OMAP2+: Move GPMC initcall to devices.c
This will us allow to just move gpmc.c to live under drivers
in the next patch.

Note that we now also remove the omap specific check for the
initcall. That's OK as gpmc_probe() checks for the pdata
and bails out for other platforms compiled in.

Also the postcore_initcall() maybe possible to change to
just regular module_init(), but let's do that in separate
patch after the move to drivers is done.

Andreas Fenkart 326119c992 mmc: omap_hsmmc: remove unnecessary omap_hsmmc_slot_data indirection
omap_hsmmc supports only one slot per controller, see OMAP_MMC_MAX_SLOTS.
This unnecessary indirection leads to confusion in the omap_hsmmc driver.
For example the card_detect callback is not installed by platform code
but from the driver probe function. So it should be a field of
omap_hsmmc_host. But since it is declared under the platform slot while
the drivers struct omap_hsmmc_host has no slot abstraction, this looks
like a bug, especially when not familiar that this driver only supports
1 slot anyway.
Either we should add a slot abstraction to omap_hsmmc_host or remove
it from the platform data struct. Removed since slot multiplexing is
an un-implemented feature

Andreas Fenkart 5514343890 ARM: OMAP1/2+: MMC: separate platform data for mmc and mmc hs driver
- omap mmc driver supports multiplexing, omap_mmc_hs doesn't
this leads to one of the major confusions in the omap_hsmmc driver

- platform data should be read-only for the driver
most callbacks are not set by the omap3 platform init code while still
required. So they are set from the driver probe function, which is against
the paradigm that platform-data should not be modified by the driver
typical examples are card_detect, read_only callbacks

un-bundling by searching for driver name \"omap_hsmmc in the
arch/arm folder. omap_hsmmc_platform_data is not initialized directly,
but from omap2_hsmmc_info, which is defined in a separate header file
not touched by this patch

hwmod includes platform headers to declare features of the platform. All
the declared features are prefixed OMAP_HSMMC. There is no need to
include platform header from hwmod other except for feature defines

Only a few files really need that platform header. When later splitting

declaring an hs mmc platform data will have to change the platform
include, which is a good sanity check.

Hans Verkuil 1b65729a18 [media] mach-omap2: remove deprecated VIDEO_OMAP2 support
The omap2 camera driver has been deprecated for a year and is now
going to be removed. It is unmaintained and it uses an internal API
that has long since been superseded by a much better API. Worse, that
internal API has been abused by out-of-kernel trees (i.MX6).

In addition, Sakari stated that these drivers have never been in a
usable state in the mainline kernel due to missing platform data.

Tony Lindgren e639cd5bfc ARM: OMAP2+: Prepare to move GPMC to drivers by platform data header
We still need to support platform data for omap3 until it's booting
in device tree only mode. So let's add platform_data/omap-gpmc.h for
that, and a minimal linux/omap-gpmc.h for the save and restore used
by the PM code.

Let's also keep a minimal mach-omap2/gpmc.h still around to avoid
churn on the board-*.c files. Once omap3 boots in device tree only
mode, we can drop mach-omap2/gpmc.h and we can make the data
structures in platform_data/omap-gpmc.h private to the GPMC driver.

Note that we can now also remove gpmc-nand.h and gpmc-onenand.h.

Arnd Bergmann 594b5d51c6 Drop few unused omap board files. The support for ti81xx is known to
be incomplete and broken, and the 3430sdp is only used in few automated
 boot test systems AFAIK and those have been booting in device tree only
 mode for quite some time now.
 
 Note that this branch has a dependency to the related device tree
 changes and GPMC changes sent in a separate pull request.

Felipe Balbi 79005fbd3e ARM: OMAP2+: hwmod: drop unnecessary list initialization
ml->node and sl->node are currently initialized
by means of INIT_LIST_HEAD(). That initialiation
is followed by a list_add() call.

Looking at what both these functions do we will have:

	ml->node.next = &ml->node;
	ml->node.prev = &ml->node;
	oi->master->master_ports.next.prev = &ml->node;
	ml->node.next = &oi->master->master_ports.next;
	ml->node.prev = &oi->master->master_ports;
	oi->master->master_ports.next = &ml->node;

from this, it's clear that both INIT_LIST_HEAD() calls
are unnecessary and can be safely removed.

Daniel Lezcano b82b6cca48 cpuidle: Invert CPUIDLE_FLAG_TIME_VALID logic
The only place where the time is invalid is when the ACPI_CSTATE_FFH entry
method is not set. Otherwise for all the drivers, the time can be correctly
measured.

Instead of duplicating the CPUIDLE_FLAG_TIME_VALID flag in all the drivers
for all the states, just invert the logic by replacing it by the flag
CPUIDLE_FLAG_TIME_INVALID, hence we can set this flag only for the acpi idle
driver, remove the former flag from all the drivers and invert the logic with
this flag in the different governor.

Nishanth Menon a30d81b98a ARM: OMAP4+: PM: Program CPU logic power state
CPU logic power state is never programmed in either the initialization
or the suspend/resume logic, instead, we depend on mpuss to program this
properly. However, this leaves CPU logic power state indeterminate and
most probably in reset configuration (If bootloader or other similar
software have'nt monkeyed with the register). This can make powerstate=
RET be either programmed for CSWR (logic=ret) or OSWR(logic = OFF) and
in OSWR, there can be context loss when the code does not expect it.

To prevent all these confusions, just support clearly ON, INA, CSWR,
OFF which is the intent of the existing code by explicitly programming
logic state.

NOTE: since this is a hot path (using in cpuidle), the exit path just
programs powerstate (logic state is immaterial when powerstate is ON).

Without doing this, we end up with lockups when CPUs enter OSWR and
multiple blocks loose context, when we expect them to hit CSWR.

Moved logic generic for OMAP5+ as part of the init routine by
introducing omap4_pm_init. However, the patch left the powerdomain
initial setup, an unused omap4430 es1.0 check and a spurious log
"Power Management for TI OMAP4." in the original code.

Remove the duplicate code which is already present in omap4_pm_init from
omap4_init_static_deps.

As part of this change, also move the u-boot version print out of the
static dependency function to the omap4_pm_init function.

Tony Lindgren aa25729cfd ARM: OMAP3: Fix errors for omap_l3_smx when booted with device tree
When booting omap3 in device tree mode, we're currently getting
the following errors:

omap_l3_smx omap_l3_smx.0: couldn't request debug irq
omap_l3_smx: probe of omap_l3_smx.0 failed with error -22

This is because we don't have handling in the driver for the
compatible property and instead assume platform data being
passed.

Note that this binding is already documented, and implemented
for the related omap_l3_noc driver for omap4 and later. Looks
like the binding somehow never got never implemented for this
omap_l3_smx driver though.

Let's also remove __exit_p to allow binding and unbinding
of the driver while at it.

There are cases where we have multiple device instances
connected to a single GPMC chip select. For example, there
are four UARTs on the Zoom debug boards that all share a
single chip select and a GPIO interrupt.

We do have support for this already in theory, but it's broken
because we're bailing out if the chip select is already taken.

To be able to provide checks on the chip select usage, let's
add new struct gpmc_cs_data so we can start using already
registered device names for checks.

Later on we probably want to start using struct gpmc_cs_data
as a wrapper for all the GPMC chipselect related data.

Linus Torvalds 2084becbe1 ARM: SoC fixes for 3.8-rc3
A surprisingly small batch of fixes for -rc3. Suspiciously small, I'd say.
 
 Anyway, most of this are a few defconfig updates. Some for omap to deal
 with kernel binary size (moving ipv6 to module, etc). A larger one for
 socfpga that refreshes with some churn, but also turns on a few options
 that makes the newly-added board in my bootfarm usable for testing.
 
 OMAP3 will also now warn when booted with legacy (non-DT) boot protocols,
 hopefully encouraging those who still care about some of those platforms
 to submit DT support and report bugs where needed. Nothing stops working
 though, this is just to warn for future deprecation.
 
 Beyond this, very few actual bugfixes. A PXA fix for DEBUG_LL boot hangs,
 a missing terminting entry in a dt_match array on RealView a MTD fix on
 OMAP with NAND.

Tony Lindgren 7d2911c438 net: smc91x: Fix gpios for device tree based booting
With legacy booting, the platform init code was taking care of
the configuring of GPIOs. With device tree based booting, things
may or may not work depending what bootloader has configured or
if the legacy platform code gets called.

Let's add support for the pwrdn and reset GPIOs to the smc91x
driver to fix the issues of smc91x not working properly when
booted in device tree mode.

And let's change n900 to use these settings as some versions
of the bootloader do not configure things properly causing
errors.

Tero Kristo 2196a9b84a ARM: OMAP2/3: CM: make cm_split_idlest_reg SoC calls static
CM driver has a generic API which calls the SoC specific split function
through cm_ll_data, so there is no need for the SoC specific functions to
be publicly available.

Linus Torvalds c0fa2373f8 The clk tree changes for 3.18 are dominated by clock drivers. Mostly
fixes and enhancements to existing drivers as well as new drivers. This
 tag contains a bit more arch code than I usually take due to some OMAP2+
 changes. Additionally it contains the restart notifier handlers which
 are merged as a dependency into several trees.
 
 The PXA changes are the only messy part. Due to having a stable tree I
 had to revert one patch and follow up with one more fix near the tip of
 this tag. Some dead code is introduced but it will soon become live code
 after 3.18-rc1 is released as the rest of the PXA family is converted
 over to the common clock framework.
 
 Another trend in this tag is that multiple vendors have started to push
 the complexity of changing their CPU frequency into the clock driver,
 whereas this used to be done in CPUfreq drivers.
 
 Changes to the clk core include a generic gpio-clock type and a
 clk_set_phase() function added to the top-level clk.h api. Due to some
 confusion on the fbdev mailing list the kernel boot parameters
 documentation was updated to further explain the clk_ignore_unused
 parameter, which is often required by users of the simplefb driver.
 Finally some fixes to the locking around the clock debugfs stuff was
 done to prevent deadlocks when interacting with other subsystems.

Linus Torvalds b528392669 ACPI and power management updates for 3.18-rc1
- Rework the handling of wakeup IRQs by the IRQ core such that
    all of them will be switched over to "wakeup" mode in
    suspend_device_irqs() and in that mode the first interrupt
    will abort system suspend in progress or wake up the system
    if already in suspend-to-idle (or equivalent) without executing
    any interrupt handlers.  Among other things that eliminates the
    wakeup-related motivation to use the IRQF_NO_SUSPEND interrupt
    flag with interrupts which don't really need it and should not
    use it (Thomas Gleixner and Rafael J Wysocki).
 
  - Switch over ACPI to handling wakeup interrupts with the help
    of the new mechanism introduced by the above IRQ core rework
    (Rafael J Wysocki).
 
  - Rework the core generic PM domains code to eliminate code that's
    not used, add DT support and add a generic mechanism by which
    devices can be added to PM domains automatically during
    enumeration (Ulf Hansson, Geert Uytterhoeven and Tomasz Figa).
 
  - Add debugfs-based mechanics for debugging generic PM domains
    (Maciej Matraszek).
 
  - ACPICA update to upstream version 20140828.  Included are updates
    related to the SRAT and GTDT tables and the _PSx methods are in
    the METHOD_NAME list now (Bob Moore and Hanjun Guo).
 
  - Add _OSI("Darwin") support to the ACPI core (unfortunately, that
    can't really be done in a straightforward way) to prevent
    Thunderbolt from being turned off on Apple systems after boot
    (or after resume from system suspend) and rework the ACPI Smart
    Battery Subsystem (SBS) driver to work correctly with Apple
    platforms (Matthew Garrett and Andreas Noever).
 
  - ACPI LPSS (Low-Power Subsystem) driver update cleaning up the
    code, adding support for 133MHz I2C source clock on Intel Baytrail
    to it and making it avoid using UART RTS override with Auto Flow
    Control (Heikki Krogerus).
 
  - ACPI backlight updates removing the video_set_use_native_backlight
    quirk which is not necessary any more, making the code check the
    list of output devices returned by the _DOD method to avoid
    creating acpi_video interfaces that won't work and adding a quirk
    for Lenovo Ideapad Z570 (Hans de Goede, Aaron Lu and Stepan Bujnak).
 
  - New Win8 ACPI OSI quirks for some Dell laptops (Edward Lin).
 
  - Assorted ACPI code cleanups (Fabian Frederick, Rasmus Villemoes,
    Sudip Mukherjee, Yijing Wang, and Zhang Rui).
 
  - cpufreq core updates and cleanups (Viresh Kumar, Preeti U Murthy,
    Rasmus Villemoes).
 
  - cpufreq driver updates: cpufreq-cpu0/cpufreq-dt (driver name
    change among other things), ppc-corenet, powernv (Viresh Kumar,
    Preeti U Murthy, Shilpasri G Bhat, Lucas Stach).
 
  - cpuidle support for DT-based idle states infrastructure, new
    ARM64 cpuidle driver, cpuidle core cleanups (Lorenzo Pieralisi,
    Rasmus Villemoes).
 
  - ARM big.LITTLE cpuidle driver updates: support for DT-based
    initialization and Exynos5800 compatible string (Lorenzo Pieralisi,
    Kevin Hilman).
 
  - Rework of the test_suspend kernel command line argument and
    a new trace event for console resume (Srinivas Pandruvada,
    Todd E Brandt).
 
  - Second attempt to optimize swsusp_free() (hibernation core) to
    make it avoid going through all PFNs which may be way too slow on
    some systems (Joerg Roedel).
 
  - devfreq updates (Paul Bolle, Punit Agrawal, Ãrjan Eide).
 
  - rockchip-io Adaptive Voltage Scaling (AVS) driver and AVS
    entry update in MAINTAINERS (Heiko Stübner, Kevin Hilman).

Merge tag 'pm+acpi-3.18-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull ACPI and power management updates from Rafael Wysocki:
 "Features-wise, to me the most important this time is a rework of
  wakeup interrupts handling in the core that makes them work
  consistently across all of the available sleep states, including
  suspend-to-idle.  Many thanks to Thomas Gleixner for his help with
  this work.

  Second is an update of the generic PM domains code that has been in
  need of some care for quite a while.  Unused code is being removed, DT
  support is being added and domains are now going to be attached to
  devices in bus type code in analogy with the ACPI PM domain.  The
  majority of work here was done by Ulf Hansson who also has been the
  most active developer this time.

  Apart from this we have a traditional ACPICA update, this time to
  upstream version 20140828 and a few ACPI wakeup interrupts handling
  patches on top of the general rework mentioned above.  There also are
  several cpufreq commits including renaming the cpufreq-cpu0 driver to
  cpufreq-dt, as this is what implements generic DT-based cpufreq
  support, and a new DT-based idle states infrastructure for cpuidle.

  In addition to that, the ACPI LPSS driver is updated, ACPI support for
  Apple machines is improved, a few bugs are fixed and a few cleanups
  are made all over.

  Finally, the Adaptive Voltage Scaling (AVS) subsystem now has a tree
  maintained by Kevin Hilman that will be merged through the PM tree.

  Numbers-wise, the generic PM domains update takes the lead this time
  with 32 non-merge commits, second is cpufreq (15 commits) and the 3rd
  place goes to the wakeup interrupts handling rework (13 commits).

  Specifics:

   - Rework the handling of wakeup IRQs by the IRQ core such that all of
     them will be switched over to "wakeup" mode in suspend_device_irqs()
     and in that mode the first interrupt will abort system suspend in

Linus Torvalds 8b45bc892e ARM: SoC driver updates for 3.18
These are changes for drivers that are intimately tied to some SoC
 and for some reason could not get merged through the respective
 subsystem maintainer tree.
 
 Most of the new code is for the Keystone Navigator driver, which is
 new base support that is going to be needed for their hardware
 accelerated network driver and other units.
 
 Most of the commits are for moving old code around from at91 and omap
 for things that are done in device drivers nowadays.
 
 - at91: move reset, poweroff, memory and clocksource code into drivers
   directories
 - socfpga: add edac driver (through arm-soc, as requested by Boris)
 - omap: move omap-intc code to drivers/irqchip
 - sunxi: added an RTC driver for sun6i
 - omap: mailbox driver related changes
 - keystone: support for the "Navigator" component
 - versatile: new reboot, led and soc drivers

Linus Torvalds 212fe84a6f ARM: SoC cleanups for 3.18
This time around, the cleanup branch contains mostly code removal. A number
 of board files for at91, imx and msm have become obsolete because of the
 DT conversion and are now ready to be removed. The OMAP platform has
 traditionally had its own DMA engine abstraction and as this is being
 phased out, a lot of the original code is now unused and can be removed
 as well.
 
 S3C24xx can be simplified now that the restart code is a proper device
 driver.
 
 Finally, a number of cleanups in shmobile are done to prepare for
 the addition of new code in other branches.

Viresh Kumar bbcf071969 cpufreq: cpu0: rename driver and internals to 'cpufreq_dt'
The naming convention of this driver was always under the scanner, people
complained that it should have a more generic name than cpu0, as it manages all
CPUs that are sharing clock lines.

Also, in future it will be modified to support any number of clusters with
separate clock/voltage lines.

Lets rename it to 'cpufreq_dt' from 'cpufreq_cpu0'.

Tero Kristo c08ee14cc6 clk: ti: change clock init to use generic of_clk_init
Previously, the TI clock driver initialized all the clocks hierarchically
under each separate clock provider node. Now, each clock that requires
IO access will instead check their parent node to find out which IO range
to use.

This patch allows the TI clock driver to use a few new features provided
by the generic of_clk_init, and also allows registration of clock nodes
outside the clock hierarchy (for example, any external clocks.)

In order to handle errata I688, a page of sram was reserved by doing a
static iotable map. Now that we use gen_pool to manage sram, we can
completely remove all of these static mappings and use gen_pool_alloc()
to get the one page of sram space needed to implement errata I688.
omap_bus_sync will be NOP until SRAM initialization happens.

In sprz318f.pdf "Usage Note 2.7" says that UARTs cannot acknowledge
idle requests in smartidle mode when configured for DMA operations.
This prevents L4 from going idle. So let's use manual idle mode
instead.

Otherwise systems using Sebastian's 8250 patches with DMA will
never enter deeper idle states because of the errata above.

Ezequiel García fef775caa7 nand: omap2: Add support for flash-based bad block table
This commit adds a new platform-data boolean property that enables use
of a flash-based bad block table. This can also be enabled by setting
the 'nand-on-flash-bbt' devicetree property.

If the flash BBT is not enabled, the driver falls back to use OOB
bad block markers only, as before. If the flash BBT is enabled the
kernel will keep track of bad blocks using a BBT, in addition to
the OOB markers.

As explained by Brian Norris the reasons for using a BBT are:

""
The primary reason would be that NAND datasheets specify it these days.
A better argument is that nobody guarantees that you can write a
bad block marker to a worn out block; you may just get program failures.

This has been acknowledged by several developers over the last several
years.

Additionally, you get a boot-time performance improvement if you only
have to read a few pages, instead of a page or two from every block on
the flash.

Tony Lindgren 7db143b891 ARM: OMAP3: Fix I/O chain clock line assertion timed out error
We are getting "PRM: I/O chain clock line assertion timed out" errors
on early omaps for device tree based booting. This is because we are
unconditionally calling reconfigure_io_chain while legacy booting
has omap3_has_io_chain_ctrl() checks in place in omap_hwmod.c.

For device tree based booting, we are calling reconfigure_io_chain
unconditionally from pinctrl framework. So we need to add a check for
omap3_has_io_chain_ctrl() to avoid the errors for trying to access
a register that does not exist.

For es3.0, the documentation in "4.11.2 Device Off-Mode Configuration"
just mentions PM_WKEN_WKUP[8] bit. For es3.1, there's a new chapter in
documentation for "4.11.2.2 I/O Wake-Up Mechanism" that describes the
PM_WKEN_WKUP[16] ST_IO_CHAIN bit. So PM_WKEN_WKUP[16] bit did not get
added until in es3.1 probaly to fix issues with flakey wake-up events.

We are doing proper checks for ST_IO_CHAIN already in id.c and with
omap3_has_io_chain_ctrl(). For more information, see also commit
b02b917211 ("ARM: OMAP3: PM: fix I/O wakeup and I/O chain clock
control detection").

Let's fix the issue by selecting the right function during init for
reconfigure_io_chain depending on the omap revision. For es3.0 and
earlier we need to just toggle EN_IO. By doing this, we can move the
check for omap3_has_io_chain_ctrl() from omap_hwmod.c to the init code
in prm_3xxx.c. And then we can unconditionally call reconfigure_io_chain.

Thanks to Paul Walmsley and Nishanth Menon for help with debugging the
issue.

Uwe Kleine-König 58cda01ed1 ARM: omap2: make arrays containing machine compatible strings const
The definition

	static const char *omap3_boards_compat[] __initconst = {

defines a changable array of constant strings. That is you must not do:

	*omap3_boards_compat[0] = 'f';

but

	omap3_boards_compat[0] = "another string";

is fine. So the annotation __initconst is wrong and yields a compiler
error when other really const variables are added with __initconst.

As the struct machine_desc member dt_compat is declared as

	const char *const *dt_compat;

making the arrays const is the better alternative over changing all
annotations to __initdata.

Nishanth Menon bd002d7bda ARM: OMAP2+: powerdomain: introduce logic for finding valid power domain
powerdomain configuration in OMAP is done using PWRSTCTRL register for
each power domain. However, PRCM lets us write any value we'd like to
the logic and power domain target states, however the SoC integration
tends to actually function only at a few discrete states. These valid
states are already in our powerdomains_xxx_data.c file.

So, provide a function to easily query valid low power state that the
power domain is allowed to go to.

Based on work originally done by Jean Pihet <j-pihet@ti.com>
https://patchwork.kernel.org/patch/1325091/ . There is no attempt to
create a new powerdomain solution here, except fixing issues seen
attempting invalid programming attempts. Future consolidation to the
generic powerdomain framework should consider this requirement as
well.

Similar solutions have been done in product kernels in the past such
as:

Rajendra Nayak f7f7a29bf0 ARM: DRA7: hwmod: Add dra74x and dra72x specific ocp interface lists
To deal with IPs which are specific to dra74x and dra72x, maintain seperate
ocp interface lists, while keeping the common list for all common IPs.

Move USB OTG SS4 to dra74x only list since its unavailable in
dra72x and is giving an abort during boot. The dra72x only list
is empty for now and a placeholder for future hwmod additions which
are specific to dra72x.

Tony Lindgren cc824534d4 ARM: OMAP2+: hwmod: Rearm wake-up interrupts for DT when MUSB is idled
Looks like MUSB cable removal can cause wake-up interrupts to
stop working for device tree based booting at least for UART3
even as nothing is dynamically remuxed. This can be fixed by
calling reconfigure_io_chain() for device tree based booting
in hwmod code. Note that we already do that for legacy booting
if the legacy mux is configured.

My guess is that this is related to UART3 and MUSB ULPI
hsusb0_data0 and hsusb0_data1 support for Carkit mode that
somehow affect the configured IO chain for UART3 and require
rearming the wake-up interrupts.

In general, for device tree based booting, pinctrl-single
calls the rearm hook that in turn calls reconfigure_io_chain
so calling reconfigure_io_chain should not be needed from the
hwmod code for other events.

So let's limit the hwmod rearming of iochain only to
HWMOD_FORCE_MSTANDBY where MUSB is currently the only user
of it. If we see other devices needing similar changes we can
add more checks for it.

Markus Pargmann 9a02ae4ed4 ARM: OMAP2+: omap_device: remove warning that clk alias already exists
When an alias for a clock already exists the warning is printed. For
every module with a main_clk defined, a clk alias for fck is added.
There are some components that have the same main_clk defined, so this
is a really normal situation.

For example the am33xx edma device has 4 components using the same main
clock. So there are three warnings in the boot log for this already
existing clock alias:
	platform 49000000.edma: alias fck already exists
	platform 49000000.edma: alias fck already exists
	platform 49000000.edma: alias fck already exists

As this is only interesting for developers, this patch changes the
message to a debug message.

Roger Quadros a3e83f05fb ARM: OMAP2+: GPMC: Support Software ECC scheme via DT
For v3.14 and prior, 1-bit Hamming code ECC via software was the
default choice for some boards e.g. 3430sdp.
Commit ac65caf514 in v3.15 changed the behaviour
to use 1-bit Hamming code via Hardware using a different ECC layout
i.e. (ROM code layout) than what is used by software ECC.

This ECC layout change causes NAND filesystems created in v3.14
and prior to be unusable in v3.15 and later. So don't mark "sw" scheme
as deperecated and support it.

Roger Quadros 7d5929c1f3 mtd: nand: omap: Revert to using software ECC by default
For v3.12 and prior, 1-bit Hamming code ECC via software was the
default choice. Commit c66d039197 in v3.13 changed the behaviour
to use 1-bit Hamming code via Hardware using a different ECC layout

This ECC layout change causes NAND filesystems created in v3.12

specified.

 Note that these are based on earlier omap-for-v3.17/soc.
 No strict dependency to it though, but I already merged in

 these are all SoC related.

Linus Torvalds d4e1f5a14e ARM: SoC device-tree changes for 3.17
Unlike the board branch, this keeps having large sets of changes for
 every release, but that's quite expected and is so far working well.
 
 Most of this is plumbing for various device bindings and new platforms,
 but there's also a bit of cleanup and code removal for things that
 are moved from platform code to DT contents (some OMAP clock code in
 particular).
 
 There's also a pinctrl driver for tegra here (appropriately acked),
 that's introduced this way to make it more bisectable.
 
 I'm happy to say that there were no conflicts at all with this branch
 this release, which means that changes are flowing through our tree as
 expected instead of merged through driver maintainers (or at least not
 done with conflicts).
 
 There are several new boards added, and a couple of SoCs. In no particular
 order:
 
 * Rockchip RK3288 SoC support, including DTS for a dev board that they
   have seeded with some community developers.
 * Better support for Hardkernel Exynos4-based ODROID boards.
 * CCF conversions (and dtsi contents) for several Renesas platforms.
 * Gumstix Pepper (TI AM335x) board support
 * TI eval board support for AM437x
 * Allwinner A23 SoC, very similar to existing ones which mostly has
   resulted in DT changes for support. Also includes support for an Ippo
   tablet with the chipset.
 * Allwinner A31 Hummingbird board support, not to be confused with the
   SolidRun i.MX-based Hummingboard.
 * Tegra30 Apalis board support

Linus Torvalds 44c916d58b ARM: SoC cleanups for 3.17
This merge window brings a good size of cleanups on various
 platforms. Among the bigger ones:
 
 * Removal of Samsung s5pc100 and s5p64xx platforms. Both of these have
   lacked active support for quite a while, and after asking around nobody
   showed interest in keeping them around. If needed, they could be
   resurrected in the future but it's more likely that we would prefer
   reintroduction of them as DT and multiplatform-enabled platforms
   instead.
 * OMAP4 controller code register define diet. They defined a lot of registers
   that were never actually used, etc.
 * Move of some of the Tegra platform code (PMC, APBIO, fuse, powergate)
   to drivers/soc so it can be shared with 64-bit code. This also converts them
   over to traditional driver models where possible.
 * Removal of legacy gpio-samsung driver, since the last users have been
   removed (moved to pinctrl)
 
 Plus a bunch of smaller changes for various platforms that sort of
 dissapear in the diffstat for the above. clps711x cleanups, shmobile
 header file refactoring/moves for multiplatform friendliness, some misc
 cleanups, etc.

Merge tag 'cleanup-for-3.17' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

Pull ARM SoC cleanups from Olof Johansson:
 "This merge window brings a good size of cleanups on various platforms.
  Among the bigger ones:

   - Removal of Samsung s5pc100 and s5p64xx platforms.  Both of these
     have lacked active support for quite a while, and after asking
     around nobody showed interest in keeping them around.  If needed,
     they could be resurrected in the future but it's more likely that
     we would prefer reintroduction of them as DT and
     multiplatform-enabled platforms instead.

   - OMAP4 controller code register define diet.  They defined a lot of
     registers that were never actually used, etc.

   - Move of some of the Tegra platform code (PMC, APBIO, fuse,
     powergate) to drivers/soc so it can be shared with 64-bit code.
     This also converts them over to traditional driver models where
     possible.

   - Removal of legacy gpio-samsung driver, since the last users have
     been removed (moved to pinctrl)

  Plus a bunch of smaller changes for various platforms that sort of
  dissapear in the diffstat for the above.  clps711x cleanups, shmobile
  header file refactoring/moves for multiplatform friendliness, some
  misc cleanups, etc"

Merge tag 'pm+acpi-3.17-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull ACPI and power management updates from Rafael Wysocki:
 "Again, ACPICA leads the pack (47 commits), followed by cpufreq (18
  commits) and system suspend/hibernation (9 commits).

  From the new code perspective, the ACPICA update brings ACPI 5.1 to
  the table, including a new device configuration object called _DSD
  (Device Specific Data) that will hopefully help us to operate device
  properties like Device Trees do (at least to some extent) and changes
  related to supporting ACPI on ARM.

  Apart from that we have hibernation changes making it use radix trees
  to store memory bitmaps which should speed up some operations carried
  out by it quite significantly.  We also have some power management
  changes related to suspend-to-idle (the "freeze" sleep state) support
  and more preliminary changes needed to support ACPI on ARM (outside of
  ACPICA).

  The rest is fixes and cleanups pretty much everywhere.

  Specifics:

   - ACPICA update to upstream version 20140724.  That includes ACPI 5.1
     material (support for the _CCA and _DSD predefined names, changes
     related to the DMAR and PCCT tables and ARM support among other
     things) and cleanups related to using ACPICA's header files.  A
     major part of it is related to acpidump and the core code used by

   - Fixes for issues related to ACPI button events (Rafael J Wysocki).

   - New device ID for an ACPI-enumerated device included into the

   - ACPI-based device hotplug cleanups from Wei Yongjun and Rafael J
     Wysocki.

   - Cleanups and improvements related to system suspend from Lan
     Tianyu, Randy Dunlap and Rafael J Wysocki.

   - cpufreq core fixes from Viresh Kumar.

     and intel_pstate driver cleanups from Stratos Karafotis.

   - Fix for the imx6 cpufreq driver from Anson Huang.

   - cpuidle core and governor cleanups from Daniel Lezcano, Sandeep
     Tripathy and Mohammad Merajul Islam Molla.
