Previously, Message Processor always generated
CRC byte at end of message.
Now(version 8), this CRC byte is generated only upon request.
To request that a checksum is generated, the MSBit
of the address of the Message Processor object is set to 1.
By default the CRC byte is not generated, reading the CRC byte
will remove new messages from IC causing lost touches.
Added control flag and message size correction for this feature.

Add an ioctl to allow the TX fifo to be loaded with data before playback

-- Use consistently the various state flags:
-- active is set only when there is a read or write in flight
-- recording_canncelled is set only when recording is stopped via the ioctl()
-- dma_has_it is used to determine whether DMA is already in flight; do not
use the state of the fifos for this (e.g., if the TX fifo is empty, do not
assume that playback is stopped)
-- added a stop_completion (implemented for readers only) so that readers
closing a stream can wait until DMA or PIO transactions are stopped
-- Split /dev/audio0_{in,out} into /dev/audio0_{in,in_ctl,out,out_ctl} where the
_ctl versions have the ioctl()s
-- Introduced an error count per audio_stream; error count is reset on open, can

-- Allocate max-sized buffers during probe, and allow the user to resize them
only within the original allocation, to avoid the risk from kmalloc failing
due to kernel-heap fragmentation, and also to avoid race conditions on DMA
shut-down.
-- In tegra_audio_write(), moved the call to start_playback_if_necessary()

smaller than what the user is trying to write, the user will block before
playback is started.

this adds support for dynamically reprogramming the I2C controller's
pin mux on transaction boundaries to enable one controller to be
registered as multiple I2C bus adapters with the kernel. this allows
platform designers an additional tool to resolve clock rate, I/O
voltage and electrical loading restrictions between the platform's
peripherals.
the i2c-tegra platform data is extended to support this; platforms
which use this feature should pass in the number of busses which
should be created for each controller, the starting adapter number
to use and the clock rate and pin mux for each virtual bus.

If you switch the cgroup of a sleeping thread, its vruntime does
not get adjusted correctly for the difference between the
min_vruntime values of the two groups.
This patch adds a new callback, prep_move_task, to struct sched_class
to give sched_fair the opportunity to adjust the task's vruntime
just before setting its new group. This allows us to properly normalize
a sleeping task's vruntime when moving it between different cgroups.

Introduce new platform callback hooks for cpuacct for tracking CPU frequencies
Not all platforms / architectures have a set CPU_FREQ_TABLE defined
for CPU transition speeds. In order to track time spent in at various
CPU frequencies, we enable platform callbacks from cpuacct for this accounting.
Architectures that support overclock boosting, or don't have pre-defined
frequency tables can implement their own bucketing system that makes sense
given their cpufreq scaling abilities.
New file:
cpuacct.cpufreq reports the CPU time (in nanoseconds) spent at each CPU
frequency.
