Subject: [PATCH 228/277] ASoC: pcm512x: revert downstream changes
|
|
|
|
This partially reverts commit 185ea05465aac8bf02a0d2b2f4289d42c72870b7
|
|
which was added by https://github.com/raspberrypi/linux/pull/1152
|
|
|
|
The downstream pcm512x changes caused a regression, it broke normal
|
|
use of the 24bit format with the codec, eg when using simple-audio-card.
|
|
|
|
The actual bug with 24bit playback is the incorrect usage
|
|
of physical_width in various drivers in the downstream tree
|
|
which causes 24bit data to be transmitted with 32 clock
|
|
cycles. So it's not the pcm512x that needs fixing, it's the
|
|
soundcard drivers.
