Subject: [PATCH 0/1] drm/bridge: tc358775: Remove burst mode support

DSI operation mode is configured to support burst mode, but bridge
driver does not correctly implement it. 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:
