[Sound-open-firmware] [PATCH v2 0/7] SSP: baytrail 24 bits support

[Keyon Jie]

This series is created to change the SSP format setting
for both Tx and Rx, and it is verified on MinnowMax +
ALC5651 codec with I2S stereo both SSP_CLK_EXT and
SSP_CLK_AUDIO mode. Changes including:
1. change ssp clock from 25M to 19.2M;
2. add 16bit <==> 24bit volume converting functions;
3. change to get dai format from host;
4. change to get ssp stream format from host;
5. remove the shim SSP divider and use SSCR0.SCR
for BCLK generating.

changes from v1:
1. change to make dai format configurable;
2. change to make ssp stream format configurable;
3. clean shim SSP divider code;
4. optimize volume copy functions.

Keyon Jie (7):
  ssp: switch to use SCR for BCLK generation.
  platform: switch default ssp clock to 19.2M
  volume: add 16bit<==>24bit volume copy function and mapping
  ssp: switch dai format form PCM B mode to normal I2S mode
  intel-ipc: get dai format from ipc
  dai: add stream_format to dai_data for codec stream
  intel-ipc: change to get ssp stream format from ipc
