After tc358768_setup_pll() enables PLL_CKEN and the lock indicator comes up, the DSI register sequence runs near immediately. On TF700T this results in the bridge claiming PLL lock but producing no DSI video output: the panel powers up, the backlight comes on, but the framebuffer is never scanned out.
Insert a small settling delay between PLL setup and the rest of the attach. Svyatoslav Ryhel (1): gpu/drm: bridge: tc358768: Add delay after PLL setup drivers/gpu/drm/bridge/tc358768.c | 3 +++ 1 file changed, 3 insertions(+) -- 2.51.0
