[PATCH] dt-bindings: dma: qcom,bam: require one of control methods

From: Krzysztof Kozlowski
Date: Mon Jun 26 2023 - 10:56:55 EST


The BAM DMA resources can be controlled remotely (e.g. by trusted
environment; needs qcom,powered-remotely or qcom,controlled-remotely
properties) or locally. In the latter case we need to provide its
clock.

Require one of methods of such control to properly validate DTS.
