Subject: arm64: dts: imx8mq-librem5-devkit: Use 0.9V for VDD_GPU
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=76eceb0f3696a2021f407a5e649aa36d08a61be5;p=linux.git

arm64: dts: imx8mq-librem5-devkit: Use 0.9V for VDD_GPU

According to the imx8mq data sheet running VDD_GPU at 0.9V is enough
when not overclocking to 1GHz (which we currently don't do).
