X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=347155d1fa85972ac19d1bf58ae3f3ce95e51a5d;p=linux.git

arm64: dts: imx8mn: remove GPU power domain reset

The PGC (power gating controller) already handles the reset for the
GPUMIX power domain. By specifying it within the device tree the reset
it issued a 2nd time. This confuses the hardware during power up and
sporadically hangs the SoC. Fix this by removing the reset property and
let the hardware handle the reset.
