Subject: [PATCH] arm64: dts: imx8mn-venice-gw7902: disable gpu
Date: Thu, 16 Dec 2021 08:12:27 -0800 [thread overview]
Message-ID: <20211216161227.31960-1-tharvey@gateworks.com> (raw)
Since commit 99aa29932271 ("arm64: dts: imx8mn: Enable GPU")
imx8mn-venice-gw7902 will hang during kernel init because it uses
a MIMX8MN5CVTI which does not have a GPU.
Disable pgc_gpumix to work around this. We also disable the GPU devices
that depend on the gpumix power domain and pgc_gpu to avoid them staying
in a probe deferred state forever.
