Subject: [PATCH] ASoc: wm8731: add 32bit mode.
|
|
|
|
commit cf5ef3a299ba32f6ac24c3c6ba18c1b7f1b5475f upstream.
|
|
|
|
This patch adds 32 bit word capability to the wm8731 driver. The wm8731
|
|
codec is capable of handling 32 bit word sizes, however that has not
|
|
previously been activated in the codec driver.
