This results in bad LVDS timings when bridge is connected to DSI host that sets higher transmission rate on DSI link, than indicated by CRTC pixel clock. TC358775 power up sequence is still broken. This change was tested with Michael's Walle series: https://lore.kernel.org/all/20240506-tc358775-fix-powerup-v1-0-545dcf00b8dd@kernel.org/ Daniel Semkowicz (1): drm/bridge: tc358775: Remove burst mode support drivers/gpu/drm/bridge/tc358775.c | 3 +-- 1 file changed, 1 insertion(+), 2 deletions(-)
