- mods kernel do not enable audio related configs in kernel
- tegra_is_voice_call_active() is defined only when audio
related configs are enabled
- this commit adds a default implementation for tegra_is_voice_call_active()
which can be called from generic pm code in mach-tegra
- it also makes the default implementation inline

Add required ioctl constants for i2s loopback tests.
Audio test framework is using these ioctls for setting
pcm format paramters for I2S loopback test.

-- Ignore kfifo thresholds on recording and playback and adjust the delays.
-- Take out the code from TEGRA_AUDIO_IN_STOP into a separate function
stop_recording_nosync()
-- Rename stop_recording() to wait_for_recording_to_stop().
-- add ioctl(TEGRA_AUDIO_OUT_FLUSH), which blocks the caller until the output
fifo is drained. While the caller is blocked, pending write() calls will
return immediately with whatever data they had managed to queue up.
-- removed ioctl(TEGRA_AUDIO_OUT_PRELOAD_FIFO)
-- since TEGRA_AUDIO_OUT_FLUSH and TEGRA_AUDIO_IN_STOP act similarly, moved
audio_driver_state::recording_cancelled to audio_stream::stop and changed
the code accordingly. Renamed functions wait_for_recording_to_stop() and
stop_recording_nosync() to wait_till_stopped() and request_stop_nosync()
since they handle both playback and recording.
-- print errors on close() if wakelocks are still held
-- Call request_stop_nosync() on close() of a recording file handle
-- Do not use struct audio_stream::active for playback streams. Instead,
where applicable, use kfifo_len(). As a consequence, playback kfifo
underruns are no longer reported. These were bogus anyway, as we really
need the DMA engine to tell us if there are underruns.
-- Because of above item, had to rework tx_fifo_atn_store(),
rx_fifo_atn_store(), and __attr_fifo_atn_write().
-- Set struct audio_stream::active for a recording stream to true when a
recording starts, and set it to false when recording get stopped. Do not
set/clear it within the body of read(), because just being within read()
does not mean that recording is in progress.
-- In tegra_audio_read(), check for stop == true before calling
start_recording_if_necessary(); this makes sure that if a user calls read()
after calling ioctl(TEGRA_AUDIO_IN_STOP), recording will not resume unless
ioctl(TEGRA_AUDIO_IN_START) gets called, or the file is closed and
re-opened.
-- Fixed TEGRA_AUDIO_IN_START
-- In PIO mode, enabled FIFOs before enabling interrupts as specified in the
TRM.
-- Added missing break in tegra_audio_ioctl().
-- Silenced some debug spew

Added an ioctl to set the bit format for I2S between "DSP"/"PCM" mode and
normal mode (set by board file)

This patch replaces the error counter with two separate error counters, one for
late dma callbacks, and another for overruns (during recording) or underruns
(during playback). The ioctls TEGRA_AUDIO_IN_GET_ERROR_COUNT and
TEGRA_AUDIO_OUT_GET_ERROR_COUNT now take a pointer to a struct containing both
error counters.

Add an ioctl to allow the TX fifo to be loaded with data before playback
starts. Playback can then be started by calling write() on the FIFO, even
with a length of 0. This will cause the pending data to be played out.

-- 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
be read back & reset through an ioctl

-- Add ioctls for configuring buffer, threshold, and DMA-transaction sizes from
user space.
-- Buffer sizes are provided in orders of magnitude.
-- 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()
immediately after writing to the fifo. Otherwise, when the fifo size is
smaller than what the user is trying to write, the user will block before
playback is started.
-- Silenced printk spew on spinning on i2s registers after transactions are
completed.
-- Cleaned up a 80-col style violation in downsample()

downsampling:
-- add ioctl()s to downsample recorded data
-- supported frequencies are 8kHz, 11.025kHz, 22.05kHz, and 44.1kHz
-- downsamping to stereo and mono
-- default is 11.025kHz mono
fixes:
-- fix crashes from dequeuing DMA requests twice
