2014-12-11audio: sai: Add Power Management supportAlison Wang
This patch adds Power Management support for SAI. Activate regmap cache with REGCACHE_RBTREE, and use regmap cache code to save and restore registers in suspend and resume. The Transmit Control Register (TCSR) and Receive Control Register(RCSR) should be volatile registers.

2014-12-11ls102xa: audio: Workaround for SAI data transfer endian issueAlison Wang
Transmit Data Register(TDR) used as the destination address of EDMA transaction is in big-endian mode. The audio data in memory and EDMA transaction are in little-endian mode. For S16_LE format data, a workaround is to swap the original 16-bit data, and then write into the higher 16 bit of TDR.
