[alsa-devel] [PATCH 0/20] ASoC: rsnd: add Synchronous SRC and U/O error salvage support

[Kuninori Morimoto]

Hi Mark.

These patches adds [1] Synchronous SRC, [2] under/over run error salvage
support to Renesas sound driver.

1) - 16) : prepare cleanup/tidyup for 17) - 19)
17)      : Synchronous SRC
18)- 19) : salvage support for under/over run error
20)      : cleanup for 18) - 19)

Current Renesas sound can use Asynchronous/Synchronous sampling rate convert.
Asynchronous sampling rate convert is already supported on upstream.
("feature" is supported, "DT" bindings is not yet supported)
17) adds Synchronous sampling rate convert.

Renesas sound has HW bug (?) which switches L/R channel if
under/over run error had occurred.
18) - 19) adds salvage supported for it.

20) is cleanup patch which is based on 18)-19) patch

Kuninori Morimoto (20):
       1. ASoC: rsnd: add .fallback callback
       2. ASoC: rsnd: add callback status check method
