Subject: [WIP] dt-bindings: dma: dw-axi-dmac: Increase DMA channel limit to 16
|
|
|
|
The first DMAC instance in the StarFive JH7100 SoC supports 16 DMA
|
|
channels.
|
|
|
|
FIXME Given there are more changes to the driver than just increasing
|
|
DMAC_MAX_CHANNELS, we probably need a new compatible value, too.
