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.

What are the units? Use '-bits' suffix.
Yes, its unit should be bit.
Do you mean that you prefer to use "qcom, cmb-element-size-bits"?
Do I also need to replace "qcom, dsb-element-size" with "qcom, dsb-element-size-bits".

Specifies the CMB(Continuous Multi-Bit) element size supported bythe monitor. The associated aggregator will read this size before itis enabled. CMB element size currently only supports 32-bit and 64-bit.The enum says 8-bit is supported.
Yes, 8-bit is supported. I will update the description in the next patch series.
Best,
