The GPU SRAM supply is supposed to be always at least 0.1V higher than the GPU supply. However when the DT was upstreamed, the spread was incorrectly set to 0.01V.

Fixes: 8855d01fb81f ("arm64: dts: mediatek: Add MT8186 Krabby platform based Tentacruel / Tentacool") Cc: stable@vger.kernel.org Signed-off-by: Chen-Yu Tsai wenst@chromium.org --- Noticed this while trying to align the downstream Mali driver to the upstream device tree and binding.
