From 66c466dae8a620010df24b636c3cffd15292e2bb Mon Sep 17 00:00:00 2001 From: Fei Shao Date: Tue, 1 Oct 2024 19:27:25 +0800 Subject: [PATCH] arm64: dts: mediatek: mt8188: Move vdec1 power domain under vdec0 The MT8188 video decoder pipeline has two hardware IP blocks: LAT and Core, which are powered by vdec0 and vdec1 power domains, respectively. The hardware design includes a dependency between the vdec0 and vdec1 power domains to ensure that Core is powered down before LAT. Without correctly describing this dependency in DT, the system will fail to suspend. As a comparable reference, MT8192 also uses the LAT + Core decoding pipeline, and it has the correct power domain dependency defined in DT. Update vdec1 as a sub-domain of vdec0 in MT8188 DT to reflect the hardware design. Also, use more specific clock names for both power domains.
