Subject: [PATCH v3 0/3] Add runtime PM for SAI digital audio interface

First patch fixes a bug by correctly setting is_slave_mode, then
second patch adds support for runtime PM and finally 3rd patch moves
clock handling from startup/shtudown function to runtime PM handlers.

Changes since v2: (after Viorel's comments)
	- no need to check for is_slave_mode when enabling/disabling the clocks
	because sai->mclk_streams is only set when SAI is in master mode.

Changes since v1: (after Nicolin's comments)
	- added patch 1
	- added fsl_sai_remove in order to call pm_runtime_disable
	- only disable/enable mclk when SAI in master mode.

Daniel Baluta (2):
  ASoC: fsl_sai: Update is_slave_mode with correct value
  ASoC: fsl_sai: Add support for runtime pm

Shengjiu Wang (1):
  ASoC: fsl_sai: Move clock operation to PM runtime
