[PATCH v2 01/10] arm64: dts: mt8183: Fix Mali GPU clock

From: AngeloGioacchino Del Regno <angelogioacchino.delregno@collabora.com>
Date: 2022-09-15 07:25:27
Also in: linux-clk, linux-devicetree, linux-mediatek, lkml
Subsystem: arm/mediatek soc support, the rest · Maintainers: Matthias Brugger, AngeloGioacchino Del Regno, Linus Torvalds

From: Chen-Yu Tsai <wenst@chromium.org>

The actual clock feeding into the Mali GPU on the MT8183 is from the
clock gate in the MFGCFG block, not CLK_TOP_MFGPLL_CK from the TOPCKGEN
block, which itself is simply a pass-through placeholder for the MFGPLL
in the APMIXEDSYS block.

Fix the hardware description with the correct clock reference.
