Subject: [PATCH] FROMLIST(v1): drm/meson: add shutdown function to meson_drv
Problem: random stucks on reboot stage about 1/20 stuck/reboots
// debug kernel log
[ 4.496660] reboot: kernel restart prepare CMD:(null)
[ 4.498114] meson_ee_pwrc c883c000.system-controller:power-controller: shutdown begin
[ 4.503949] meson_ee_pwrc c883c000.system-controller:power-controller: shutdown domain 0:VPU...
...STUCK...
Solution: add shutdown function to meson_drm driver
// debug kernel log
