From deebc79b28d6e9ec4d5086bbf1766b65aadcb531 Mon Sep 17 00:00:00 2001 From: Bjorn Andersson Date: Thu, 25 Jan 2024 13:05:09 -0800 Subject: [PATCH] clk: qcom: gpucc-sc8280xp: Add external supply for GX gdsc On SA8295P and SA8540P the GFX rail is powered by a dedicated external regulator, instead of the rpmh-controlled "gfx.lvl". Define the "vdd-gfx" as the supply regulator for the GDSC, to cause the gdsc logic to look for, and control, this external power supply.
