X-Git-Tag: v6.6.17~3937^2~23^2~705
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=55cac10739d57b94de4626bcb009bcdafaa781af;p=platform%2Fkernel%2Flinux-rpi.git

drm/bridge: tc358762: Set pre_enable_prev_first

Set the "pre_enable_prev_first" as provided by commit 4fb912e5e190
("drm/bridge: Introduce pre_enable_prev_first to alter bridge init
order"). This should allow us to revert commit ec7981e6c614
("drm/msm/dsi: don't powerup at modeset time for parade-ps8640") and
commit 7d8e9a90509f ("drm/msm/dsi: move DSI host powerup to modeset
time").
