[PATCH 0/2] dt-bindings: Add SpacemiT K1 PDMA request-number header and use it in DT

Posted by Guodong Xu 9 hours ago

Currently, K1 device trees specify PDMA peripheral requests as raw numbers.
Add a dt-bindings header naming those request lines, point the binding's
dma-cells description at it, and convert the current user (the K1 SPI3
node) to the new K1_PDMA_* macros.

Patch 1 adds include/dt-bindings/dma/spacemit,k1-pdma.h with the
  K1_PDMA_* request-number macros and update the spacemit,k1-pdma binding's
  dma-cells description.
Patch 2 updates the current pdma user in k1.dtsi to use these request
  number macros.
