Subject: [PATCH] arm64: dts: rockchip: Add i2s1 on rk356x
|
|
|
|
This adds the necessary device tree node on rk3566 and rk3568
|
|
to enable the I2S1 TDM audio controller.
|
|
|
|
I2S0 has not been added, as it is connected to HDMI and there is
|
|
no way to test that it's working without a functioning video
|
|
clock (read: VOP2 driver).
