[PATCH v2 3/4] dt-bindings: PCI: dwc: rockchip: Add dma properties

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Niklas Cassel <niklas.cassel@xxxxxxx>

Even though rockchip-dw-pcie.yaml inherits snps,dw-pcie.yaml
using:

allOf:
  - $ref: /schemas/pci/snps,dw-pcie.yaml#

and snps,dw-pcie.yaml does have the dma properties defined, in order to be
able to use these properties, while still making sure 'make CHECK_DTBS=y'
pass, we need to add these properties to rockchip-dw-pcie.yaml.
