Subject: Re: [PATCH] drm: rockchip: add shutdown function to poweroff VOP and
 HDMI TX

Hi,

Just found out that this was patched and reverted before.(lol)
The revert was 3 months ago for RK3399 boards, but other processors
like RK3066 are left without shutdown now.

What's the status for a fix?
Keep using the old patch for now?


drm/rockchip: shutdown drm subsystem on shutdown
https://patchwork.kernel.org/patch/10556151/

[for-4.20] Revert "drm/rockchip: Allow driver to be shutdown on reboot/kexec"
