This patch fix a bug in the register indexing for GPIOs numbers > 31
to get the relevant hardware registers of tnetv107x to control the GPIOs.
In the structure tnetv107x_gpio_regs:
struct tnetv107x_gpio_regs {
u32 idver;
u32 data_in[3];
u32 data_out[3];
u32 direction[3];
u32 enable[3];
};
The GPIO hardware register addresses of tnetv107x are stored.
The chip implements 3 registers of each entity to serve 96 GPIOs,
each register provides a subset of 32 GPIOs.
The driver provides these macros: gpio_reg_set_bit, gpio_reg_get_bit
and gpio_reg_clear_bit.
The bug implied the use of macros to access the relevant hardware
register e.g. the driver code used the macro like this:
'gpio_reg_clear_bit(®->data_out, gpio)'
But it has to be used like this:
'gpio_reg_clear_bit(reg->data_out, gpio)'.
The different results are shown here:
- ®->data_out + 1 (it will add the full array size of data_out i.e. 12 bytes)
- reg->data_out + 1 (it will increment only the size of data_out i.e. only 4 bytes)

Set up the GPTIMER hwmod used for the clockevent source immediately
before it is used. This avoids the need to set up all of the hwmods
until the boot process is further along. (In general, we want to defer
as much as possible until late in the boot process.)
This second version fixes a bug pointed out by Santosh Shilimkar
<santosh.shilimkar@ti.com>, that would cause the kernel to use an
incorrect timer hwmod name if the selected GPTIMER was not 1 or 12 -
thanks Santosh. Also, Tarun Kanti DebBarma <tarun.kanti@ti.com>
pointed out that the original patch did not apply cleanly; this has

Add omap_hwmod_setup_one(), which is intended for use early in boot to
selectively setup the hwmods needed for system clocksources and
clockevents, and any other hwmod that is needed in early boot.
omap_hwmod_setup_all() can then be called later in the boot process.
The point is to minimize the amount of code that needs to be run
early.

Previously, if a hwmod had already been set up, and the code attempted
to set up the hwmod again, an error would be returned. This is not
really useful behavior if we wish to allow the OMAP core code to setup
the hwmods needed for the Linux clocksources and clockevents before
the rest of the hwmods are setup. So, instead of generating errors,
just ignore the attempt to re-setup the hwmod.

Move the code that looks for the MPU initiator hwmod to run during
the individual hwmod _register() function. (Previously, it ran after
all hwmods were registered in the omap_hwmod_late_init() function.)
This is done so code can late-initialize a few individual hwmods --
for example, for the system timer -- before the entire set of hwmods is
initialized later in boot via omap_hwmod_late_init().

Migrating to clkdev has several advantages:
* Less code in mach-msm/clock.c
* A more robust clk_get() implementation
* clk_add_alias() support
* clk_get_sys() support
In general, this will help board authors setup clock aliases and
break the dependency on device pointers in the clock tables.

Not all devices use proc_comm and determining if a clock is local
vs. remote is fragile when done by comparing clk_ops pointers.
Instead, implement an is_local() function for all clk_ops to
determine if the clock is local. Doing this allows us to remove
the last references to clk_ops_pcom from clock.c and compile it
for targets with CONFIG_MSM_PROC_COMM=n.
We don't need to set the clk_ops at runtime until 7x30 local
clock detection comes in. Right now it's just complicating things
so just set the ops pointer statically.

There's no longer any reason why we should prevent multiple
calls to omap_hwmod_init(). It is now simply used to register an
array of hwmods.
This should allow a subset of hwmods (e.g., hwmods
handling the system clocksource and clockevents) to be registered
earlier than the remaining mass of hwmods.

They noticed when only 4 bytes were set to 0 instead of 8,
everything worked correctly.
Mathew pointed out:

| We're supposed to be resetting trampoline_phys_low and
| trampoline_phys_high here, which are two 16-bit values.
| Writing 64 bits is definitely going to overwrite space

We currently presume a 4x expansion to guess the decompressed kernel size
in order to determine if the decompressed kernel is in conflict with
the location where zImage is loaded. This guess may cause many issues
by overestimating the final kernel image size:
- This may force a needless relocation if the location of zImage was
fine, wasting some precious microseconds of boot time.
- The relocation may be located way too far, possibly overwriting the
initrd image in RAM.
- If the kernel image includes a large already-compressed initramfs image
then the problem is even more exacerbated.
And if by some strange means the 4x guess is too low then we may overwrite
ourselves with the decompressed image.
So let's use the exact decompressed kernel image size instead. For that
we need to rely on the stat command, but this is hardly a new build
dependency as the kernel already depends on many external commands
to be built provided by the coreutils package where stat is found.
