Subject: [PATCH 239/277] Revert downstream wm8804 changes
|
|
|
|
The format change from S24_LE to S24_3LE effectively disables 24-bit
|
|
mode as S24_3LE isn't supported by bcm2835-i2s. This causes issues
|
|
with drivers that want to use wm8804 in 24-bit mode.
|
|
|
|
Adding the S32_LE format is also incorrect, according to the datasheet
|
|
only 16-24 bit formats are supported.
