Hi Mark

These are bugfix patches for Renesas sound SSI driver.
SSI1 can share clock pin with SSI0, and then, I had assumed that
SSI0 clock output needs SSICR::EN bit.
But, it wasn't. SSI0 clock output for SSI1 needs other settings
which already sets, but EN was not needed.
Because of this assumption, and SSICR::EN operation bug, it gets
underrun error in some sound route. This patch solves this issue.

Kuninori Morimoto (3):
  ASoC: rsnd: control SSICR::EN correctly
  ASoC: rsnd: move rsnd_ssi_config_init() execute condition into it.
  ASoC: rsnd: rsnd_ssi_can_output_clk() macro
