The commit b63128e812 broke the pin muxing

Fix this by defining the board registration function omap_register_i2c_bus
in common platform code as it was before but keep the muxing in architecture

Paul Walmsley 43b40992ce OMAP hwmod: add hwmod class support
Add support for categorizing and iterating over hardware IP blocks by
the "class" of the IP block.  The class is the type of the IP block:
e.g., "timer", "timer1ms", etc.  Move the OCP_SYSCONFIG/SYSSTATUS data
from the struct omap_hwmod into the struct omap_hwmod_class, since
it's expected to stay consistent for each class.  While here, fix some
comments.

The hwmod_class structures in this patch were designed and proposed by
Benoît Cousson <b-cousson@ti.com> and were refined in a discussion
between Thara Gopinath <thara@ti.com>, Kevin Hilman
<khilman@deeprootsystems.com>, and myself.

This patch uses WARN() lines that are longer than 80 characters, as
Kevin noted a broader lkml consensus to increase greppability by
keeping the messages all on one line.

Paul Walmsley 50ebdac2ec OMAP hwmod: convert hwmod to use hardware clock names rather than clkdev dev+con
The OMAP hwmod core code is intended to use SoC IP block description
structures that are autogenerated from TI's OMAP hardware database.
Currently the hwmod code uses clkdev device + connection addressing to
identify clocks.  This causes problems in the hwmod autogeneration
process, since the TI hardware database doesn't use platform_device or
clkdev addressing; it uses a single clock signal name string, which
tends to bear some resemblance to what is used in the OMAP TRMs.  This
patch converts the hwmod code and existing data to use omap_clk_get_by_name(),
introduced in the previous patch.

Paul Walmsley 74be842743 OMAP clock: add omap_clk_get_by_name() for use by OMAP hwmod core code
The OMAP hwmod core code is intended to use SoC IP block description
structures that are autogenerated from TI's OMAP hardware database.
Currently the hwmod code uses clkdev device + connection addressing to
identify clocks.  This causes problems in the hwmod autogeneration
process, since the TI hardware database doesn't use platform_device or
clkdev addressing; it uses a single clock signal name string, which
tends to bear some resemblance to what is used in the OMAP TRMs.  This
patch adds a non-exported function to the OMAP clock code,
omap_clk_get_by_name().  A subsequent patch will convert the hwmod
code to use this function.

This function is for use only by core code, and practically, no other
code outside the hwmod code should need it.  Device driver code in the
kernel must not use this function, which is why it is not exported.
Drivers should use the appropriate clock alias provided by the clkdev
data structures, so driver code can be completely SoC-independent.

Paul Walmsley 51c1954162 OMAP clock: drop RATE_FIXED clock flag
The RATE_FIXED clock flag is pointless.  In the OMAP1 clock code, it
simply causes the omap1_clk_round_rate() function to return the
current rate of the clock.  omap1_clk_round_rate(), however, should
never be called for a fixed-rate clock, since none of these clocks
have a .round_rate function pointer set in their struct clk records.
Similarly, in the OMAP2+ clock code, the RATE_FIXED flag just causes
the clock code to emit a warning if the OMAP clock maintainer was
foolish enough to add a .round_rate function pointer to a fixed-rate
clock.  "Doctor, it hurts when I pretend that a fixed-rate clock is
rate-changeable."  "Then don't pretend that a fixed-rate clock is
rate-changeable."  It has no functional value.  This patch drops the
RATE_FIXED clock flag, removing it from all clocks that are so marked.

Paul Walmsley 8c34974ab0 OMAP2 clock: drop DELAYED_APP clock flag
All of the clocks that are marked with DELAYED_APP are changed as part
of the virt_prcm_set OPP virtual clock.  On 24xx, these clocks all
need to be changed as part of a group to keep the clock tree
functional - hence the need for the VALID_CONFIG bit, which is not
present on later OMAPs.  These clocks should not be rate-changed
independently.  So prevent these clocks from being changed
independently by dropping their .round_rate and .set_rate function
pointers.  It then turns out that the DELAYED_APP clock flag is no
longer useful, so drop it and the associated code and renumber the
clock flags.

Paul Walmsley 1a3377176b OMAP2 clock: drop CONFIG_PARTICIPANT clock flag
It turns out that the only purpose of the CONFIG_PARTICIPANT clock
flag is to prevent omap2_clk_set_rate() and omap2_clk_set_parent()
from being executed on clocks with that flag set.  The rate-changing
component can be more directly accomplished by dropping the .set_rate
and .round_rate function pointers from those CONFIG_PARTICIPANT struct
clks.  As far as the parent-changing component is concerned, it turns
out that none of the CONFIG_PARTICIPANT clocks have multiple parent
choices, so all that is necessary is for omap2_clk_set_parent() to
bail out early if the new parent is equal to the old parent.
Implement this change and get rid of the flag, which has always had a
confusing name (it appears to be a Kconfig option, falsely).

Paul Walmsley 93340a2294 OMAP2/3/4 clock: fix DPLL multiplier value errors; also copyrights, includes, documentation
The maximum DPLL multiplier (M) values for OMAP2xxx and OMAP3xxx are
one increment higher than they should be.  See for example the
OMAP242x TRM Rev X Section 5.10.6 "Clock Generator Registers" and the
OMAP36xx TRM Rev C Table 3-202 "CM_CLKSEL1_PLL".  Programming a 0 into
the DPLL's M register bitfield is valid for OMAP2/3 and indicates that
the DPLL should enter MN-bypass mode.  Also, increase the minimum
multiplier (M) value for the DPLL rate rounding code from 1 to 2, to
ensure that it does not inadvertently put the DPLL into bypass.

Note that the register documentation in the OMAP2xxx and OMAP3xxx TRMs
does not make clear that the actual DPLL divider value (the "N") is
the content of the appropriate register bitfield for the N value,
_plus one_.  (In other words, an N register bitfield of 0 indicates a
DPLL divider value of 1.)  This is only clearly documented in the
OMAP4430 TRM, in, for example, OMAP4430 TRM Rev A Table 3-1167
"CM_CLKSEL_DPLL_USB".

While here, update copyrights, add kerneldoc for struct dpll_data,
drop the unused struct dpll_data.max_tolerance field, remove some
unnecessary #includes in DPLL-related code, and replace the #include
of <linux/module.h> with <linux/list.h>, which is what was really
needed.  The OMAP4 clock autogenerator script has been updated
accordingly.

Vishwanath BS 7356f0b26b OMAP3 clock: add support for 192Mhz DPLL4M2 output
In 3630, DPLL4M2 output can be 96MHz or 192MHz (for SGX to run at
192). This patch has changes to support this feature. 96MHz clock is
generated by dividing 192Mhz clock by 2 using CM_CLKSEL_CORE register.
SGX can select Core Clock, 192MHz clock or CM_96M_FCLK as it's
functional clock. In summary changes done are:
1. Added a feature called omap3_has_192mhz_clk and enabled for 3630
2. Added a new clock node called omap_192m_alwon_ck
3. Made omap_96m_alwon_fck to derive its clock from omap_192m_alwon_ck

Thara Gopinath 358f0e630d OMAP3: hwmod: support to specify the offset position of various SYSCONFIG register bits.
In OMAP3 Some modules like Smartreflex do not have the regular sysconfig
register.Instead clockactivity bits are part of another register at a
different bit position than the usual bit positions 8 and 9.

In OMAP4, a new scheme is available  due to the new protocol
between the PRCM and the IPs. Depending of the scheme, the SYSCONFIG
bitfields position will be different.
The IP_REVISION register should be at offset 0x00.
It should contain a SCHEME field. From this we can determine whether
the IP follows legacy scheme or the new scheme.

31:30 SCHEME  Used to distinguish between old scheme and current.
 Read 0x0:  Legacy protocol.
 Read 0x1:  New PRCM protocol defined for new OMAP4 IPs

For legacy IP
 13:12 MIDLEMODE
 11:8  CLOCKACTIVITY
 6     EMUSOFT
 5     EMUFREE
 4:3   SIDLEMODE
 2     ENAWAKEUP
 1     SOFTRESET
 0     AUTOIDLE

For new OMAP4 IP's, the bit position in SYSCONFIG is (for simple target):
 5:4   STANDBYMODE (Ex MIDLEMODE)
 3:2   IDLEMODE (Ex SIDLEMODE)
 1     FREEEMU (Ex EMUFREE)
 0     SOFTRESET

Unfortunately In OMAP4 also some IPs will not follow any of these
two schemes. This is the case at least for McASP, SmartReflex
and some security IPs.

This patch introduces a new field sysc_fields in omap_hwmod_sysconfig which
can be used by the hwmod structures to specify the offsets for the
sysconfig register of the IP.Also two static structures
omap_hwmod_sysc_type1 and omap_hwmod_sysc_type2 are defined
which can be used directly to populate the sysc_fields if the IP follows
legacy or new OMAP4 scheme. If the IP follows none of these two schemes
a new omap_hwmod_sysc_fields structure has to be defined and
passed as part of omap_hwmod_sysconfig.

Current implementation defines clock idle state indicators based on the
cpu information (cpu_is_omap24xx() or cpu_is_omap34xx()) in a system wide

indicators to be defined on a per clock basis if required.

This is specifically needed on AM35xx devices as the new IPSS clocks
indicates the idle status (0 is idle, 1 is ready) in a way just
opposite to how its handled in OMAP3 (0 is ready, 1 is idle).

Kevin Hilman 0007122ad8 OMAP: omap_device: add omap_device_is_valid()
The omap_device struct contains a 'struct platform_device'.  Normally,
converting a platform_device pointer to an omap_device pointer
consists of simply doing a container_of(), as is done currently by the
to_omap_device() macro.

However, if this is attempted when using platform_device that has not
been created as part of the omap_device creation, the container_of()
will point to a memory location before the platform_device pointer
which will contain random data.

Therefore, we need a way to detect valid omap_device pointers.  This
patch solves this by using the simple magic number approach.

Adrian Hunter e0eb242446 omap_hsmmc: Allow for a shared VccQ
EMMC can have two voltage supplies, Vcc and VccQ
which are implemented in the code as consumer
supplies vmmc and vmmc_aux.

If the regulator that supplies vmmc_aux is shared
with other consumers, then sending it to sleep
will disrupt those consumers.  However, the
TWL4030-family regulators may have OFF remapped
to SLEEP, in which case 'regulator_disable()'
will put the regulator to sleep only when all
consumers are disabled - which is the desired
behaviour.

This patch adds a platform data field to allow
that option.

This patch moves the setup code for GPIO's and Voltage
Regulators from the board file mmc-twl4030.c to the
driver omap_hsmmc.c.  PBIAS and other system control
configuration remains in the board file.

Moving GPIO code to the driver makes the board initialisation
code independent of when GPIO's are defined.  That makes the
board initialisation now entirely independent of its original
twl4030 roots.

Moving Voltage Regulator code to the driver allows for further
development of regulator support in the core MMC code.  It also
permits the MMC core to be compiled as a module, because the
board code no longer calls MMC core functions.

This patch adds 'board-sdp-flash.c', which could be utilized
by boards similar to 3430SDP. (For ex: 2430sdp, 36030sdp).

This file does initialization for all three flash devices present
in SDP boards (NOR, NAND, OneNAND), by finding there 'cs' number
dynamically using switch setting information (S8: 1-4).
This also expects partition information from core board files (for
ex: board-3430sdp.c). Which allows to choose different default
partitions for different boards.

A new structure is created for this purpose: 'flash_partitions'
in 'mach/board-sdp.h'. This has two members:
1. struct mtd_partition *parts
2. int nr_parts

A board file is expected to fill this structure and pass it to
'sdp-flsash-init'. Partition information should be passed in
structure array of 'flash_partitions'. Partition information should
be passed in below sequence in array:
NOR
OneNAND
NAND

Kevin Hilman 9799aca203 OMAP: omap_device: optionally auto-adjust device activate/deactivate latencies
First, this patch adds new worst-case latency values to the
omap_device_pm_latency struct.  Here the worst-case measured latencies
for the activate and deactivate hooks are stored.

In addition, add an option to auto-adjust the latency values used for
device activate/deactivate.

By setting a new 'OMAP_DEVICE_LATENCY_AUTO_ADJUST' flag in the
omap_device_pm_latency struct, the omap_device layer automatically
adjusts the activate/deactivate latencies to the worst-case measured
values.

Anytime a new worst-case value is found, it is printed to the console.
Here is an example log during boot using UART2 s an example.  After
boot, the OPP is manually changed to the 125MHz OPP:

[...]
Freeing init memory: 128K
omap_device: serial8250.2: new worst case deactivate latency 0: 30517
omap_device: serial8250.2: new worst case activate latency 0: 30517
omap_device: serial8250.2: new worst case activate latency 0: 218139648
omap_device: serial8250.2: new worst case deactivate latency 0: 61035
omap_device: serial8250.2: new worst case activate latency 0: 278076171
omap_device: serial8250.2: new worst case activate latency 0: 298614501
omap_device: serial8250.2: new worst case activate latency 0: 327331542

/ # echo 125000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_setspeed

omap_device: serial8250.2: new worst case deactivate latency 0: 91552

Motivation: this can be used as a technique to automatically determine
the worst case latency values.  The current method of printing a
warning on every violation is too noisy to actually interact the
console in order to set low OPP to discover latencies.

Another motivation for this patch is that the activate/deactivate
latenices can vary depending on the idlemode of the device.  While
working on the UARTs, I noticed that when using no-idle, the activate
latencies were as high as several hundred msecs as shown above.  When
the UARTs are in smart-idle, the max latency is well under 100 usecs.

Paul Walmsley 369d561445 OMAP clockdomains: add usecounting for wakeup and sleep dependencies
Add usecounting for wakeup and sleep dependencies.  In the current
situation, if several functions add dependencies on the same
clockdomains, when the first dependency removal function is called,
the dependency will be incorrectly removed from the hardware.

Add clkdm_clear_all_wkdeps() and clkdm_clear_all_sleepdeps(), which
provide a fast and usecounting-consistent way to clear all hardware
clockdomain dependencies, since accesses to these registers can be
quite slow.  pm{2,3}4xx.c has been updated to use these new functions.
The original version of this patch did not touch these files, which
previously wrote directly to the wkdep registers, and thus confused
the usecounting code.  This problem was found by Kevin Hilman
<khilman@deeprootsystems.com>.

N.B.: This patch introduces one significant functional difference over
the previous pm34xx.c code: sleepdeps are now cleared during
clockdomain initialization, whereas previously they were left
untouched.  This has been tested by Kevin and confirmed to work.

The original version of this patch also did not take into
consideration that some clockdomains do not have sleep or wakeup
dependency sources, which caused NULL pointer dereferences.  This
problem was debugged and fixed by Kevin Hilman
<khilman@deeprootsystems.com>.

Paul Walmsley e909d62a8a OMAP clockdomain/powerdomain: remove runtime register/unregister
OMAP clockdomains and powerdomains are currently defined statically,
only registered at boot, and never unregistered, so we can remove the
unregister function and the locking.   A variant of this was originally
suggested a while ago by Dmitry Baryshkov <dbaryshkov@gmail.com>.
This version of this patch contains an additional fix from Kevin Hilman
<khilman@deeprootsystems.com> to address one of the pwrdm_for_each_nolock()
users in mach-omap2/pm-debug.c.   Thanks Kevin.

Move clockdomain wakeup dependency and sleep dependency data
structures from the powerdomain layer to the clockdomain layer, where
they belong.  These dependencies were originally placed in the
powerdomain layer due to unclear documentation; however, it is clear
now that these dependencies are between clockdomains.  For OMAP2/3,
this is not such a big problem, but for OMAP4 this needs to be fixed.

Thara Gopinath 883edfdd58 OMAP3: hwmod: Adding flag to prevent caching of sysconfig register.
In the current implementation the sysconfig value is read into
 _sysc_cache once and an actual update to the sysconfig register
happens only if the new value paased is differnt from the one in _sysc_cache.
_sysc_cache is updated only if _HWMOD_SYSCONFIG_LOADED is not set.
This can lead to the follwing issue if off mode is enabled in modules
which employs "always-retore" mechanism of context save and restore.

        a. The module sets the sysconfig register through omap_device_enable.
           Here _sysc_cache is updated with the value written to the sysconfig
           register and left.
        b. The power domain containig the module enters off mode and the
           module context is lost.
        c. The module in use becomes active and calls omap_device_enable to
           enable itself. Here a read of sysconfig register does not happen
           as _HWMOD_SYSCONFIG_LOADED flag is set. The value to be written
           to the sysconfig register will be same as the one written in step a.
           Since _sysc_cache reflects the previous written value an update
           of the sysconfig register does not happen.
This means in modules which employs "always-restore" mechanism
after off , the sysconfig regsiters will never get updated.

This patch introduces a flag SYSC_NO_CACHE which if set ensures that the
sysconfig register is always read into _sysc_cache before an update is
attempted.

This flags need to be set only by modules which does not do a context save
but re-initializes the registers every time the module is accessed. This
includes modules like i2c, smartreflex etc.

This patch fills in the OCP_SYSCONFIG.AUTOIDLE handling in the OMAP
hwmod code.

After this patch, the hwmod code will set the module AUTOIDLE bit
(generally <module>.OCP_SYSCONFIG.AUTOIDLE) to 1 by default upon
enable.  If the hwmod flag HWMOD_NO_OCP_AUTOIDLE is set, AUTOIDLE will
be set to 0 upon enable.  Upon module disable, AUTOIDLE will be set to
1.

Enabling module autoidle should save some power.  The only reason to
not set the OCP_SYSCONFIG.AUTOIDLE bit is if there is a bug in the
module RTL, e.g., the MPUINTC block on OMAP3.

Paul Walmsley 6f8b7ff5b0 OMAP clock/hwmod: fix off-by-one errors
Fix loop bailout off-by-one bugs reported by Juha Leppänen
<juha_motorsportcom@luukku.com>.

This second version incorporates comments from Russell King

Tomi Valkeinen 640f9ca5fd OMAP: Add support for VRFB rotation engine
VRFB rotation engine is a block in OMAP2/3 that offers 12 independent
contexts that can be used for framebuffer rotation.

Each context has a backend area of real memory, where it stores the
pixels in undisclosed format. This memory is offered to users via 4
virtual memory areas, which see the same memory area in different
rotation angles (0, 90, 180 and 270 degrees).

Tomi Valkeinen afedec183e OMAP: Add VRAM manager
Add a Video RAM manager for OMAP 2 and 3 platforms. VRAM manager is used
to allocate large continuous blocks of SDRAM or SRAM. The features VRAM
manager has that are missing from dma_alloc_* functions are:

- Support for OMAP2's SRAM
- Allocate without ioremapping
- Allocate at defined physical addresses
- Allows larger VRAM area and larger allocations

The upcoming DSS2 uses VRAM manager.

VRAM area size can be defined in kernel config, board file or with
kernel boot parameters. Board file definition overrides kernel config,
and boot parameter overrides kernel config and board file.

Paul Walmsley 13a0322957 omap3: drop all IVA-related address base definitions
All of the OMAP3 IVA physical address macros in
plat-omap/include/plat/omap34xx.h are wrong[1]:

OMAP34XX_IVA_INTC_BASE: The IVA interrupt controller does not appear
to be accessible from the L3 interconnect, and in any case is
definitely not at 0x40000000; the latter address appears to be the
internal IVA physical address base for the OMAP2420's interrupt control[2].

OMAP34XX_DSP_BASE: The section of L3 physical address space mapped to
the IVA starts at 0x5c000000, not 0x58000000.

OMAP34XX_DSP_MEM_BASE: It's not clear what this refers to, but it's not
in the L3 IVA address space.

OMAP34XX_DSP_IPI_BASE: The Intrusive Port Interface is a relic from
the OMAP2420 days and no longer applies to OMAP3.

OMAP34XX_DSP_MMU_BASE: The DSP MMU is mapped at 0x5d000000, not 0x5a000000.


Nothing that uses these can possibly be working, so drop them.  When
future code needs these, correct versions can be added in.

Nishanth Menon 2456a10fb3 omap3: Introduce OMAP3630
OMAP3630 is the latest in the family of OMAP3 devices
and among the changes it introduces are:

New OPP levels for new voltage and frequency levels. a bunch of
Bug fixes to various modules feature additions, notably with ISP,
sDMA etc.

Details about the chip is available here:
http://focus.ti.com/general/docs/wtbu/wtbuproductcontent.tsp?templateId=6123&navigationId=12836&contentId=52606

Strategy used:
Strategy to introduce this device into Linux was discussed here:
Ref: http://marc.info/?t=125343303400003&r=1&w=2

Two approaches were available:
a) Consider 3630 generation of devices as a new family of silicon
b) Consider 3630 as an offshoot of 3430 family of devices

As a common consensus, (b) seems to be more valid for 3630 as:
* There are changes which are easily handled by using "FEATURES"
  infrastructure.
  For details how to do this, see thread:
  http://marc.info/?t=125050998500001&r=1&w=2
* Most of existing 34xx infrastructure can be reused(almost 90%+)
	- so no ugly if (cpu_is_omap34xx() || cpu_is_omap36xx())
	  all over the place
	- lesser chance of bugs due to reuse of proven code flow
	- 36xx specific handling can still be done where required
	  within the existing infrastructure

NOTE:
* If additional 34xx series are added, OMAP3430_REV_ESXXXX can be
  added on top of the existing 3630 ones are renumbered

This patch was tested on SDP3430, boot tested on 3630 platform using
3430sdp defconfig

Cory Maccarrone 490a566522 omap1: mmc: Add platform init for omap7xx
The MMC mux pins normally used by omap chips in devices.c
are different from what is needed by omap7xx chips.  This
change adds a conditional around the mux setup code to
enable the correct mux pins.

The omap730 and omap850 both use a different clock for the "fck"
clock of the MMC interface than other omap processors based on the
SOFT_REQ_REG, pin 12.  The "ick" clock is the same as that used
by other omap processors.

* Added the missing clock definition as mmc3_ck to clock.h
* Added the clock definition to omap_clks in clock.c
* Added CK_7XX to the mmci-omap.0 "ick" clock already in clock.c

With these changes, it is now possible to initialize and use MMC
cards with omap730 and omap850 devices.

vikram pandita d9f5007491 omap: introduce OMAP_LL_DEBUG_NONE DEBUG_LL config
Zoom2/Zoom3 kind of boards do not use omap uarts for console.
These use external debug board for console.

So these boards should not have "Uncompressing Kernel...."
log put on omap uarts.

By interoducing OMAP_LL_DEBUG_NONE option,
unnecessary writes to omap uarts is avoided.

In future, the DEBUG_LL interface will be enhanced
to use external debug board.

Alexander Shishkin 9d30b99f35 omap: Eliminate OMAP_MAX_NR_PORTS
Eliminate OMAP_MAX_NR_PORTS

Note that also the null terminator entry for omap1
serial_platform_data needs to be now removed to avoid
oopsing.

Note that mach-omap1 uses struct plat_serial8250_port
array, which requires a null terminator at the end,
and that's why we need to use ARRAY_SIZE - 1. This
is not needed on mach-omap2 as the array used is
struct omap_uart_state, and does not use a null
terminator.

Rajendra Nayak f265dc4c5d OMAP3: PM: Program SDRC to send self refresh on timeout of AUTO_CNT
Due to an OMAP3 errata (1.142), on HS/EMU devices SDRC should be
programed to issue automatic self refresh on timeout
of AUTO_CNT = 1 prior to any transition to OFF mode.
This is needed only on sil rev's ES3.0 and above.

This patch enables the above needed WA in the SDRC power register
value stored in scratchpad, so that ROM code restores this value
in SDRC POWER on the wakeup path.
The original SDRC POWER register value is stored and restored back
in omap_sram_idle() function.

This fixes some random crashes observed while stressing suspend
on HS/EMU devices.
