arch/arm/mach-omap2/gpmc.c passes a return value from ioremap() as the
fifth argument to request_irq() without casting it.  This causes
sparse to generate the following warning:

arch/arm/mach-omap2/gpmc.c:759:63: warning: incorrect type in argument 5 (different address spaces)
arch/arm/mach-omap2/gpmc.c:759:63:    expected void *dev
arch/arm/mach-omap2/gpmc.c:759:63:    got void [noderef] <asn:2>*static [toplevel] [assigned] gpmc_base

It turns out that it's not necessary to pass this.  gpmc_base is a
file-scoped static variable, the ISR is located in the same file ... and
the ISR doesn't even touch the passed-in variable.  So, just replace it with
NULL in request_irq().

pwrdm_state_switch() does wait for the powerdomain transition which is
not the case.  The missing wait for the powerdomain transition
violates the sequence which the hardware expects, which causes power
management failures on some devices.

Commit 2a9f5a4d "OMAP3 clock: remove unnecessary duplicate of dpll4_m2_ck,
added for 36xx" consolidated dpll4 clock structures between 34xx and 36xx,
but left 34xx CLKSEL masks for most dpll4 related clocks, which causes
clock code to not behave correctly when booting on DM3730 with higher
(36xx only) divisors set:

If transceiver is attached to a MMC host of ES2.1 OMAP35xx, it seems
2.1.1.128 erratum doesn't apply and there is no data corruption,
probably because of different signal timing. The workaround for this
erratum disables multiblock reads, which causes dramatic loss of
performance (over 75% slower), so avoid it when transceiver is present.

 - Boards that declare their own regulator cannot use this function.
 - Multiple calls to this function require special handling.
 - Boards that declare id's other than '0' need special handling.

On platforms such as OMAP3, certain variants may not have IVA, SGX
or some specific component. We currently have a check to aid fixing
wrong population of OPP entries for issues such as typos. This however
causes a conflict with valid requirement where the SoC variant does
not actually have the module present.

So, reduce the severity of the print to a debug statement and skip

It appears that the error paths were overlooked when the
omap3_pm_init() routine had the prcm chain handler code
added.  Fix this by adding a goto target and reordering
the error handling code.  Also fix how the irq argument
for free_irq() is determined.

On OMAP4, recently a synchronisation bug is discovered by hardware
team, which leads to incorrect timer value read from 32K sync timer
IP when the IP is comming out of idle.

The issue is due to the synchronization methodology used in the SYNCTIMER IP.
The value of the counter register in 32kHz domain is synchronized to the OCP
domain register only at count up event, and if the OCP clock is switched off,
the OCP register gets out of synch until the first count up event after the
clock is switched back -at the next falling edge of the 32kHz clock.

Further investigation revealed that it applies to gptimer1 and watchdog timer2
as well which may run on 32KHz. This patch fixes the issue for all the
applicable modules.

The BUG has not made it yet to the OMAP errata list and it is applicable to
OMAP1/2/3/4/5. OMAP1/2/3 it is taken care indirectly by autodeps.

By enabling static depedency of wakeup clockdomain with MPU, as soon as MPU
is woken up from lowpower state(idle) or whenever MPU is active, PRCM forces
the OCP clock to be running and allow the counter value to be updated properly
in the OCP clock domain.

The bug is going to fixed in future OMAP versions.

With the introduction of dynamically allocated IRQ in the twl6030 driver,
the board files can no longer rely of static IRQ defines like before.

Retrieve the value dynamically allocated from the mmc -> twl6030 init
callback.

Note: The Panda board does not seems to use the card detect IRQ.

Commit d1589f09 (ARM: OMAP2+: Mark
omap_hsmmc_init and omap_mux related functions as __init) changed DSI
muxing functions to __init. This doesn't work, as the muxing functions
are used every time a DSI display is enabled or disabled.

This patch removes the __inits from DSI mux functions that were
accidentally marked as __init, and makes omap4_hdmi_mux_pads __init
like it should be.

Several platforms create IOMEM defines for casting to 'void __iomem *',
and other platforms are incorrectly using __io() macro for the same
purpose. This creates a common definition and removes all the platform
specific versions. Rather than try to make linux/io.h and asm/io.h
assembly safe, the assembly version of IOMEM is moved into
asm/assembler.h.
