Missing new power domains, no?

[PATCH 2/3] dt-bindings: power: qcom,rpmhpd: Add new power domains and new levels

[Fenglin Wu]

Add definitions for the new power domains which present in Hawi SoC:
 - RPMHPD_DCX (Display Core X): supplies VDD_DISP for the display
   subsystem
 - RPMHPD_GBX (Graphics Box): supplies VDD_GFX_BX for the GPU/graphics
   subsystem

Also, add constants for new power domain levels that supported in Hawi
SoC, including: LOW_SVS_D3_0, LOW_SVS_D1_0, LOW_SVS_D0_0, SVS_L2_0,
TURBO_L1_0/1/2, TURBO_L1_0/1/2.

This belongs to the binding change. Unless you are not doing it for
Hawi...

Add the RPMh power domains required for the Hawi SoC. This includes
new definitions for domains supplying specific hardware components:
- DCX: supplies VDD_DISP
- GBX: supplies VDD_GFX_BX

So, should it be just mmcx or mmcx_w_cx_parent ?

It is mmcx.

There is no such requirement to vote cx before voting mmcx on Hawi SoC.
