[RESEND PATCH v6 27/27] drm/rockchip: psr: Remove flush by CRTC

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Tomasz Figa <tfiga@xxxxxxxxxxxx>

It is not used anymore after last changes and it was not even correct to
begin with as it assumed a 1:1 relation between a CRTC and encoder,
while in fact a CRTC can be attached to multiple encoders.
