Subject: [PATCH v3 1/2] dt-bindings: dma: fsl-edma: remove 'clocks' from required
fsl,imx8qm-adma and fsl,imx8qm-edma don't require 'clocks'. Remove it from
required and add 'if' block for other compatible string to keep the same
restrictions.
Acked-by: Krzysztof Kozlowski <krzysztof.kozlowski@...aro.org>
Signed-off-by: Frank Li <Frank.Li@....com>

Notes:
Change from v2 to v3
- rebase to dmaengine/next
Change from v1 to v2
- add Krzysztof's ACK.
