[PATCH 0/6] ASoC: rsnd: add CTU support

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi Mark

These patches adds CTU (= Channel Transfer Unit) support to
Renesas R-Car sound driver.
It can exchange channel order
	ex) channel {0,1,2,3} -> channel {3,2,1,0}
And it can add/reduce each channels sound
	ex) (input 0th ch x 0.5) + (input 2nd ch x 0.5) = output 1st ch
You need to check R-Car datasheet for each detail settings,
or check 6) patch

      1) ASoC: rsnd: don't call update callback if it was NULL
      2) ASoC: rsrc-card: add convert channels support
      3) ASoC: rsnd: tidyup rsnd_ssiu_init_gen2()
      4) ASoC: rsnd: add CTU basic support
      5) ASoC: rsnd: add rsnd_runtime_channel_xxx()
      6) ASoC: rsnd: add CTU support
