Subject: [PATCH] soc: mediatek: mtk-regulator-coupler: Add support for MT8189
Date: Thu, 3 Sep 2026 14:21:24 +0800 [thread overview]
Message-ID: <20260903062142.1025443-1-justin.yeh@mediatek.com> (raw)
MT8189 couples its GPU supply (buck_vgpu) with the GPU SRAM supply
(ldo_sram_gpu), which is exactly the GPU<->SRAM relationship this
coupler already handles for MT8183, MT8186, MT8188 and MT8192.
Register the coupler on MT8189 as well so that both supplies stay
voltage-balanced.
