[PATCH v2 1/2] dt-bindings: power: qcom,rpmhpd: Add RPMh power domain for Hawi SoC
From: Fenglin Wu
Date: Thu Apr 02 2026 - 20:44:15 EST
Document the RPMh power domain for Hawi SoC, and 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.
