condition to check bit-format is always false
because TEGRA20_I2S_CTRL_BIT_FORMAT_I2S is zero.

i2s bitclk for dsp mode was kept 4 times the minimum requirement
for bcm4330 bt chip on whistler we require only 2 times the minimum
requirement because modem is also configured similarly and for bt call
both the bit clocks should match

Set I2s FIFO attention level based on sample size and channel count.
Also set playback DMA destination bus width and capture DMA source bus
width based on sample size. These changes are needed to have proper
BT SCO playback and record which uses 16bit-mono format.

when system resumes from suspend state the i2s/das/spdif registers
have power on reset values, this change restores the registers
with their prior values from cache

Add support for Tegra20 mono playback/capture. Mono is only supported
using DSP mode.
Also reduce minimum period bytes limit to 128 to have an acceptable
latency value for 8kHz-mono playback/capture.

Remove redundant ref counting for I2s and AHUB clocks.
For Tegra30 enable AHUB clocks before I2s registers are accessed.
Disable clocks when they are not in use.

Rename these files so they include a specific hardware version in their
filenames. The contents is only touched minimally so that git's rename
tracking operates correctly; renaming all symbols in the files results
in a diff so large that the rename detection fails.
