Subject: dt-bindings: dma: allwinner,sun50i-a64-dma: Add compatibles for A523
|
|
|
|
There are two DMA controllers on the A523, one in the main system area
|
|
and the other for the MCU. These are the same as the one found on the
|
|
A100. The only difference is the DMA endpoint (DRQ) layout.
|
|
|
|
Since the number of channels and endpoints are described with additional
|
|
generic properties, just add new A523-specific compatible strings and
|
|
fallback to the A100 one.
