Subject: [PATCH 114/146] ASoC: sun4i-i2s: Add compatibility with A64 codec I2S
|
|
|
|
The I2S block used for the audio codec in the A64 differs from other 3
|
|
I2S modules in A64 and isn't compatible with H3. But it is very similar
|
|
to what is found in A10(sun4i). However, its TX FIFO is
|
|
located at a different address.
