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
records and struct clk records to omit clockdomain information if the
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
6c4a057bff ("ARM: OMAP4: clock data:

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.

While I was at it, I also made the dtb generation more generic, i.e. if
the platform is enabled then all dtbs for that platform will be created.

The real time counter also called master counter, is a free-running
counter. It produces the count used by the CPU local timer peripherals
in the MPU cluster. The timer counts at a rate of 6.144 MHz.
The ratio registers needs to be configured based on system clock
only onetime. After initialisation, hardware takes care of adjusting
the clock in different low power modes to keep counter rate constant.

Enable pinctrl dummy states for all OMAP platforms that don't

pinctrl data. These platforms already have pinmuxes configured

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.

At some point we were planning to pass the bootloader information
with custom atags that did not work out too well.
There's no need for these any longer as the kernel has been booting
fine without them for quite some time. And Now we have device tree
support that can be used instead.

Clean up and standardize several parts of

These can now be moved to be local headers in mach-omap2.
Note that this patch removes arch/arm/plat-omap/devices.c as it
will get removed anyways with Paul Walmsley's patch
"ARM: OMAP: split OMAP1, OMAP2+ RNG device registration".
Signed-off-by: Tony Lindgren <tony@atomide.com>
As the plat and mach includes need to disappear for single zImage work,
we need to remove plat/hardware.h.
Do this by splitting plat/hardware.h into omap1 and omap2+ specific files.
The old plat/hardware.h already has omap1 only defines, so it gets moved
to mach/hardware.h for omap1. For omap2+, we use the local soc.h
that for now just includes the related SoC headers to keep this patch more
readable.
Note that the local soc.h still includes plat/cpu.h that can be dealt
with in later patches. Let's also include plat/serial.h from common.h for
all the board-*.c files. This allows making the include files local later
on without patching these files again.
Note that only minimal changes are done in this patch for the
drivers/watchdog/omap_wdt.c driver to keep things compiling. Further
patches are needed to eventually remove cpu_is_omap usage in the drivers.
Also only minimal changes are done to sound/soc/omap/* to remove the
unneeded includes and to define OMAP44XX_MCPDM_L3_BASE locally so there's
no need to include omap44xx.h.
While at it, also sort some of the includes in the standard way.

As the interrupts should only be defined in the platform_data, and
eventually coming from device tree, there's no need to define them
in header files.
Let's remove the hardcoded references to irqs.h and fix up the includes
so we don't rely on headers included in irqs.h. Note that we're
defining OMAP_INTC_START as 0 to the interrupts. This will be needed
when we enable SPARSE_IRQ. For some drivers we need to add
#include <plat/cpu.h> for now until these drivers are fixed to
remove cpu_is_omapxxxx() usage.
While at it, sort som of the includes the standard way, and add
the trailing commas where they are missing in the related data
structures.
Note that for drivers/staging/tidspbridge we just define things
locally.

format "dcan.X", where 'X' is the dcan instance number.
On other side, driver may request for clock with/without con_id
and dev_id, and it is expected that platform should respect this
request and return the requested clock handle.
Now, when using device tree, the format of the device name created
by OF layer is different, "<reg-address>.<device-name>",
assuming that the device-tree "reg" property is specified.
This causes the look-up failure for clock node in dcan driver
To fix this add new dcan clock alias for using device-tree.

This patch adds HWMOD data for all the peripherals of
AM335X device and also hooks up to the existing OMAP framework.
hwmod data has been already been cleaned up for the recent
changes in clocktree, where all leaf nodes have been removed,
since with modulemode based control, both clock and hwmod
interface does same thing. This reduces the code size to large
extent and also avoids duplication of same control.
So instead of specifying module's leaf node as a main_clk,
now we are relying on parent clock of module's functional clock.

With the new devices (like, AM33XX and OMAP5) we now only support
DT boot mode of operation and now it is the time to start killing
slowly the dependency on hwmod, so with this patch, we are starting
with device resources.
The idea here is implemented considering to both boot modes -
- DT boot mode
OF framework will construct the resource structure (currently
does for MEM & IRQ resource) and we should respect/use these
resources, killing hwmod dependency.
If pdev->num_resources > 0, we assume that MEM & IRQ resources
have been allocated by OF layer already (through DTB).
Once DMA resource is available from OF layer, we should
kill filling any resources from hwmod.
- Non-DT boot mode
Here, pdev->num_resources = 0, and we should get all the
resources from hwmod (following existing steps)

/* Associate all the IRQs to boot CPU like GIC init does. */
for (i = 0; i < max_irqs; i++)
