From: Tomi Valkeinen <tomi.valkei...@ti.com> [ Upstream commit 4842379cbe6e851de914a7132f76f4e200b9a98b ]
tc358767 driver does not set DRM bus_flags, even if it does configures the polarity settings into its registers. This means that the DPI source can't configure the polarities correctly. Add sync flags accordingly.
