Remove the SoC restriction code from the OMAP RNG driver. The
integration code in arch/arm/*omap* should handle this. The device
shouldn't be created if it doesn't exist on the currently-booted SoC.
This allows us to remove some OMAP-specific cpu_is_omap*() calls from
the driver. Also, if other OMAP chips have RNGs that can be used
by Linux, there will be no need to modify the driver.

Move the OMAP1-specific RNG device creation off to mach-omap1/devices.c,
and create a omap_device-backed registration function for OMAP2+ devices
in mach-omap2/devices.c.
As a nice side-benefit, we can also get rid of
arch/arm/plat-omap/devices.c, thanks to some recent changes from Tony.
One change from the previous behavior is that the RNG devices are now
registered unconditionally. This should allow the RNG drivers to be
loaded as modules, even if the original kernel was not built that way.

Some IP blocks might not be using/controlling more than one
reset line, this check loosens the restriction to fully use
hwmod framework for those drivers.
E.g.: ipu has reset lines: mmu_cache, cpu0 and cpu1.
- As of now cpu1 is not used and hence (with previous check) the
IP block isn't fully enabled by hwmod code.
- Usually ipu and dsp processors configure their mmu module first
and then enable the processors, this involves:
* Deasserting mmu reset line, and enabling the module.
* Deasserting cpu0 reset line, and enabling the processor.
The ones portrayed in this example are controlled through
rproc_fw_boot in drivers/remoteproc/remoteproc_core.c
While at it, prevent _omap4_module_disable if all the hardreset
lines on an IP block are not under reset.
This will allow the driver to:
a. Deassert the reset line.
b. Enable the hwmod through runtime PM default callbacks.
c. Do its usecase.
d. Disable hwmod through runtime PM.
e. Assert the reset line.

Currently hwmod only provides the offset for the context lose
register, and if we attempt to share the same register between two or
more hwmods, the resulting context loss counts get wrong. Thus, we
need a way to specify which bits are used for the context loss
information for each. This is accomplished by adding a new field to
the omap4 prcm struct, 'lostcontext_mask', which specifies a bit-mask
to use for filtering the register.
Mark the affected hwmods appropriately. 'l4_abe' hwmod uses the
LOSTMEM_AESSMEM bit of RM_ABE_AESS_CONTEXT register, as l4_abe doesn't
have its own dedicated register for this purpose. This register is
shared with 'aess' hwmod, thus both hwmods must also specify which
bits of the register are used for them.
This patch only adds the hwmod data, but a future patch should add
code support such that only the specified bits are read and cleared by
the context lose counter update code. If a hwmod doesn't specify
'lostcontext_mask' (default behavior), the whole contents of the
context register should be used without any filtering.

On OMAP4, there is no support to read previous logic state
or previous memory state achieved when a power domain transitions
to RET. Instead there are module level context registers.
In order to support the powerdomain level logic/mem_off_counters
on OMAP4, instead use the previous power state achieved (RET) and
the *programmed* logic/mem RET state to derive if a powerdomain lost
logic or did not.
If the powerdomain is programmed to enter RET state and lose logic
in RET state, knowing that the powerdomain entered RET is good enough
to derive that the logic was lost as well, in such cases.

The decision was made a few months ago to allow struct omap_hwmod

clockdomain is not software-controllable. See for example commit
868c157df9 ("ARM: OMAP2+: hwmod: remove
prm_clkdm, cm_clkdm; allow hwmods to have no clockdomain").
So convert an existing pr_warning() to a pr_debug() (regarding missing
clockdomains in clocks), and add a pr_debug() for missing hwmod
clockdomains. It's still useful to enable these messages for
debugging, since missing clockdomains can cause hard-to-debug problems
with power management; see for example commit

As part of Common Clk Framework (CCF) the clk_enable() operation
was split into a clk_prepare() which could sleep, and a clk_enable()
which should never sleep. Similarly the clk_disable() was
split into clk_disable() and clk_unprepare(). This was
needed to handle complex cases where in a clk gate/ungate
would require a slow and a fast part to be implemented.
None of the clocks below seem to be in the 'complex' clocks
category and are just simple clocks which are enabled/disabled
through simple register writes.
Most of the instances also seem to be called in non-atomic
context which means its safe to move all of those from
using a clk_enable() to clk_prepare_enable() and clk_disable() to
clk_disable_unprepare().
For some others, mainly the ones handled through the hwmod framework
there is a possibility that they get called in either an atomic
or a non-atomic context.
The way these get handled below work only as long as clk_prepare
is implemented as a no-op (which is the case today) since this gets
called very early at boot while most subsystems are unavailable.
Hence these are marked with a *HACK* comment, which says we need
to re-visit these once we start doing something meaningful with
clk_prepare/clk_unprepare like doing voltage scaling or something
that involves i2c.
This is in preparation of OMAP moving to CCF.

For OMAP4, the dmtimers are located in the Wake-up, ABE and Peripheral (PER)
power domains. Hence, when the dmtimer is configured to use the "timer_sys_ck"
as its functional clock the actual clock used is different depending on whether
the clock is in the Wake-up, ABE or PER domain. So when we look-up the dmtimer's
"timer_sys_ck" we need to specify the timer device name as well as clock alias
to find the right clock.
Currently, the device names for the timers have the format "omap_timer.X" where
X is the timer instance number. When using to device tree, the format of the
device name created by device-tree is different and has the format
"<reg-address>.<device-name>" (this is assuming that the device-tree "reg"
property is specified). This causes the look-up for the OMAP4 "timer_sys_ck" to
fail. To fix this add new timer clock alias for using device-tree.
Please note that adding a 2nd set of clock aliases for the same clocks to only
temporary until device-tree migration is complete. Then we can remove the legacy
aliases. Hence, I have marked the legacy aliases with a "TODO" to remove them.

Merge tag 'cleanup-fixes-for-v3.7' into test_v3.6-rc6_cff3.7_odaf3.7
These fixes are needed to fix non-omap build breakage for
twl-core driver and to fix omap1_defconfig compile when
led driver changes and omap sparse IRQ changes are merged
together. Also fix warnings for omaps not using pinctrl
framework yet.
Merge of the LED related changes with omap sparse IRQ and
hardware.h related changes causes a build issue otherwise:
arch/arm/mach-omap1/board-h2.c:319: error: implicit declaration of function ‘OMAP_MPUIO’
arch/arm/mach-omap1/board-h2.c:319: error: initializer element is not constant
arch/arm/mach-omap1/board-h2.c:319: error: (near initialization for ‘h2_gpio_led_pins[1].gpio’)

Enable pinctrl dummy states for all OMAP platforms that don't
populate DT. This allows drivers to be converted to pinctrl
and not generate new warnings on platforms that do not provide
pinctrl data. These platforms already have pinmuxes configured
before the drivers probe.

Commit 7d7e1eba (ARM: OMAP2+: Prepare for irqs.h removal) broke
compile for non-omap as include plat/cpu.h was added. This header
was indirectly included earlier when SPARSE_IRQ was not set, but
does not exist on most platforms.
Fix the problem by removing the cpu_is_omap usage that should
not exist in drivers at all. We can do this by adding proper
clock aliases for the twl-core.c drivers, and drop separate
handling for cases when clock framework is not available as
the behaviour will stay the same.
Note that we need to add a platform device to avoid using the
i2c provided names that may be different on various omaps.

- A tps65217 build error fix.
- A lcp_ich regression fix caused by the MFD driver failing to initialize the
watchdog sub device due to ACPI conflicts.
- 2 MAX77693 interrupt handling bug fixes.
- An MFD core fix, adding an IRQ domain argument to the MFD device addition
API in order to prevent silent and potentially harmful remapping behaviour
changes for drivers supporting non-DT platforms.
