From 2317b87a2a6fb9e1fff3144b72330ba551856721 Mon Sep 17 00:00:00 2001 From: Rajendra Nayak Date: Fri, 17 Apr 2020 00:00:43 -0700 Subject: [PATCH] arm64: dts: qcom: db820c: Add vdd_gfx and tie it into mmcc Add the SPMI regulator node in the PMI8994, use it to give us VDD_GX at a fixed max nominal voltage for the db820c and specify this as supply for the MMSS GPU_GX GDSC. With the introduction of CPR support the range for VDD_GX should be expanded.
