Merge tag 'mtk-soc-for-v6.11' of https://git.kernel.org/pub/scm/linux/kernel/git/mediatek/linux into soc/drivers
MediaTek driver updates for v6.11
This adds the previously missed Tone Curve Conversion (TCC)
MuteX bit to enable the same in MDP3 on the the MT8188 SoC,
disables 9-bit Alpha for display HDR support in MT8195 and
adds math operation support in the Global Command Engine for
all MediaTek SoCs, which will be used in the near future in
the ISP driver.
* tag 'mtk-soc-for-v6.11' of https://git.kernel.org/pub/scm/linux/kernel/git/mediatek/linux:
soc: mtk-cmdq: Add cmdq_pkt_logic_command to support math operation
soc: mediatek: Disable 9-bit alpha in ETHDR
soc: mediatek: mtk-mutex: Add MDP_TCC0 mod to MT8188 mutex table
