Paul Walmsley 694606c4ef OMAP2+: powerdomain: add pwrdm_can_ever_lose_context()
Some drivers wish to know whether the device that they control can
ever lose context, for example, when the device's enclosing
powerdomain loses power.  They can use this information to determine
whether it is necessary to save and restore device context, or whether
it can be skipped.  Implement the powerdomain portion of this by
adding the function pwrdm_can_ever_lose_context().  This is not for
use directly from driver code, but instead is intended to be called
from driver-subarch integration code (i.e., arch/arm/*omap* code).

Currently, the result from this function should be passed into the
driver code via struct platform_data, but at some point this should
be part of some common or OMAP-specific device code.

While here, update file copyrights.

Trivial fix to remove the unused function declaration
from the powerdomain header.

Kevin Hilman 7f595674e0 OMAP2+: powerdomain: add API to get context loss count
Add new powerdomain API

    u32 pwrdm_get_context_loss_count(struct powerdomain *pwrdm)

for checking how many times the powerdomain has lost context.  The
loss count is the sum of the powerdomain off-mode counter, the
logic off counter and the per-bank memory off counter.

Paul Walmsley 72e06d0872 OMAP2+: powerdomain: move header file from plat-omap to mach-omap2
The OMAP powerdomain code and data is all OMAP2+-specific.  This seems
unlikely to change any time soon.  Move plat-omap/include/plat/powerdomain.h
to mach-omap2/powerdomain.h.  The primary point of doing this is to remove
the temptation for unrelated upper-layer code to access powerdomain code
and data directly.

As part of this process, remove the references to powerdomain data
from the GPIO "driver" and the OMAP PM no-op layer, both in plat-omap.
Change the DSPBridge code to point to the new location for the
powerdomain headers.  The DSPBridge code should not be including the
powerdomain headers; these should be removed.
