[PATCH 43/43] ASoC: cirrus: edb93xx: Delete driver

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

 



From: Alexander Sverdlin <alexander.sverdlin@xxxxxxxxx>

Can be replaced with "simple-audio-card" for the rates up to 50kHz, refer
to commit "ARM: dts: ep93xx: Add EDB9302 DT".
