Subject: arm64: dts: mediatek: mt8183-kukui: Assign sram supply to mfg_async pd
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=63859d711a13c7dd96f499b921793363db1a76dd;p=linux.git

arm64: dts: mediatek: mt8183-kukui: Assign sram supply to mfg_async pd

Add a phandle to the MT8183_POWER_DOMAIN_MFG_ASYNC power domain and
assign the GPU VSRAM supply to this in mt8183-kukui: this allows to
keep the sram powered up while the GPU is used.
