The patches were generated from the RPi repo with the following command: git format-patch v6.6.34..rpi-6.1.y Some patches needed rebasing and, as usual, the applied and reverted, wireless drivers, Github workflows, READMEs and defconfigs patches were removed.

Subject: [PATCH 1118/1135] ASoC: da7213: Add a set_bclk_ratio method
|
|
|
|
Following [1], it becomes harder for the CPU DAI to know the correct
|
|
BCLK ratio. We can either bake the same knowledge into the sound card
|
|
driver, or implement and use set_bclk_ratio on the codec. This commit
|
|
does the latter.
|
|
|
|
[1] commit c89e652e84f6 ("ASoC: da7213: Add support for mono, set
|
|
frame width to 32 when possible")
