[PATCH v2 1/8] dt-bindings: arm: Add support for CMB element size

From: Tao Zhang
Date: Tue Oct 24 2023 - 22:54:34 EST


Add property "qcom,cmb-elem-size" to support CMB(Continuous
Multi-Bit) element for TPDM. The associated aggregator will read
this size before it is enabled. CMB element size currently only
supports 32-bit and 64-bit.
