The omap_device_[enable|idle|shutdown] functions print a warning
when called from an invalid state. Print the invalid state in
the warning messages. This also uses __func__ to get the function
name.
Also, move the entire print string onto a single line to facilitate
grepping or error messages. Recent discussions on LKML show
strong preference for grep-able code vs. strict 80 column limit.

The omap_device struct contains a 'struct platform_device'. Normally,
converting a platform_device pointer to an omap_device pointer
consists of simply doing a container_of(), as is done currently by the
to_omap_device() macro.
However, if this is attempted when using platform_device that has not
been created as part of the omap_device creation, the container_of()
will point to a memory location before the platform_device pointer
which will contain random data.
Therefore, we need a way to detect valid omap_device pointers. This
patch solves this by using the simple magic number approach.

When both blocking and completion callbacks are queued for lock,
the dlm would always deliver the completion callback (cast) first.
In some cases the blocking callback (bast) is queued before the
cast, though, and should be delivered first. This patch keeps
track of the order in which they were queued and delivers them
in that order.
This patch also keeps track of the granted mode in the last cast
and eliminates the following bast if the bast mode is compatible
with the preceding cast mode. This happens when a remotely mastered
lock is demoted, e.g. EX->NL, in which case the local node queues
a cast immediately after sending the demote message. In this way
a cast can be queued for a mode, e.g. NL, that makes an in-transit
bast extraneous.

In order to have TWL6030 CODEC driver as a platform driver, codec data
should be passed through twl_platform_data structure.
For twl6030 audio codec, the following data may be passed:
- audpwron_gpio: gpio line used to power-up/down the codec. A low-to-high
transition powers codec up. Setting audpwron_gpio to a negative value
means that codec will use manual power sequence instead of automatic
sequence
- naudint_irq: irq line for audio interrupt. twl6030 drives NAUDINT line
to low when an interrupt (codec ready, plug insertion/removal, etc) is
detected
However, codec driver can operate if any or none of them are passed.

Physical DSI bus is protected by a mutex. This patch changed the mutex to
a semaphore, so that we can lock and unlock the bus_lock from different
threads.
This is needed as the update process is started by user space program, and
thus the lock is acquired in that context, but the lock can be released in
different context, a work thread via irq.

I create wrong asm code but none test shows that this part of code is wrong.
I am not convinces that were good idea to create asm optimized macros
for caches. The reason is that there is not optimization with previous code
that's why make sense to add old code and do some benchmarking which
functions are faster.

This fixes suspend/resume problem with the driver caused by the
fact that ACPI _DIS method would completely power off the SP3
module leaving the output lines (including IRQ lines) in an
undefined state. This could cause spurious interrupts and requires
reinitializing hardware from scratch during resume.

This will save ~15ms boot time.
The first 10ms sleep was introduced in commit d2595d86e5 for (buggy)
Cxt codecs, so better to limit the sleep to the problem hardware.
For the second 10ms sleep, the HDA spec says:
Power State[1:0]:
00: Node Power state (D0) is fully on.
01: Node Power state (D1) allows for (does not require) the lowest possible power consuming state from which it
can return to the "fully on" state (D0) within 10 ms, excepting analog pass through circuits (e.g., CD analog
playback) which must remain fully on.
10: Node Power state (D2) allows for (does not require) the lowest possible power consuming state from which it
can return to the "fully on" state (D0) within 10 ms. For modems, this is the "wake on ring" power state.
11: Node Power state (D3) allows for (does not require) lowest possible power consuming state under software
control. Note that any low power state set by software must retain sufficient operational capability to properly
respond to subsequent software Power State command.
So 10ms is actually the max wait time. It should be safe to
remove/reduce it and rely on the loop of 1ms-sleeps.
