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". > >> + description: >> + Specifies the CMB(Continuous Multi-Bit) element size supported by >> + the monitor.

I will continue to use the property name "qcom, cmb-element-size" in order to be consistent with "qcom, dsb-element-size". Let me know if you have any concerns about this.
