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

[Kuninori Morimoto]

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
