An API which translates a standard hwmod name to corresponding
platform_device is useful for drivers when they need to look up the
device associated with a hwmod name to map back into the device
structure pointers. These ideally should be used by drivers in
mach directory. Using a generic hwmod name like "gpu" instead of
the actual device name which could change in the future, allows
us to:
a) Could in effect help replace apis such as omap2_get_mpuss_device,
omap2_get_iva_device, omap2_get_l3_device, omap4_get_dsp_device,
etc..
b) Scale to more devices rather than be restricted to named functions
c) Simplify driver's platform_data from passing additional fields
all doing the same thing with different function pointer names
just for accessing a different device name.

Remove OMAP4_USBC1_ICUSB_PWRDNZ_MASK during enable/disable PWRDNZ mode for
MMC1_PBIAS and associated extended-drain MMC1 I/O cell. This is in accordance
with the control module programming guide. This fixes a bug where if trying to
use gpio_98 or gpio_99 and MMC1 at the same time the GPIO signal will be
affected by a changing SDMMC1_VDDS.

Software must keep MMC1_PBIAS cell and MMC1_IO cell PWRDNZ signals low whenever
SDMMC1_VDDS ramps up/down or changes for cell protection purposes.

MMC1 is based on SDMMC1_VDDS whereas USBC1 is based on SIM_VDDS therefore
they can operate independently.

That flag no longer makes sense, since we don't look up automount points
as eagerly any more.  Additionally, it turns out that the NO_AUTOMOUNT
handling was buggy to begin with: it would avoid automounting even for
cases where we really *needed* to do the automount handling, and could
return ENOENT for autofs entries that hadn't been instantiated yet.

With our new non-eager automount semantics, one discussion has been
about adding a AT_AUTOMOUNT flag to vfs_fstatat (and thus the
newfstatat() and fstatat64() system calls), but it's probably not worth
it: you can always force at least directory automounting by simply
adding the final '/' to the filename, which works for *all* of the stat
family system calls, old and new.

So AT_NO_AUTOMOUNT (and thus LOOKUP_NO_AUTOMOUNT) really were just a
result of our bad default behavior.

The concensus seems to be that system calls such as stat() etc should

This generalizes the omap2_mcbsp1_mux_clkr_src and omap2_mcbsp1_mux_fsr_src
implementation between generic McBSP and OMAP2 specific McBSP code. These
functions are used to select source for CLKR and FSR signals on OMAP2+.

Start generalizing the code by implementing an optional mux_signal function
pointer in platform data that will implement the actual muxing and which is
called now from omap2_mcbsp1_mux_clkr_src and omap2_mcbsp1_mux_fsr_src.
These functions are to be removed later and cleanup the API so that

Implement generalization by having an optional set_clk_src function pointer

pass higher level source clock name (later coming from client driver) that
platform specific code will map to platform specific clock name.
