Subject: pmdomain: qcom: rpmhpd: Add power domains for Hawi SoC
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=596ca99cf04f339db2ed18a5bb230ee11a47b699;p=thirdparty%2Fkernel%2Flinux.git

pmdomain: qcom: rpmhpd: Add power domains for Hawi SoC

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
