This patch series add bus format negotiation support for Cadence MHDP8546 bridge driver. The patch series has four patches in the below sequence: 1. drm: bridge: cdns-mhdp8546: Modify atomic_get_input_bus_format bridge function. Return all the input formats supported. 2. drm: bridge: cdns-mhdp8546: Remove setting of bus format using connector info Remove the bus format configuration using connector info structure. 3. drm: bridge: cdns-mhdp8546: Retrieve the pixel format and bpc based on bus format Get the pixel format and bpc based on negotiated output bus format.

[1] https://patchwork.kernel.org/project/dri-devel/cover/20201201121830.29704-1-nikhil.nd@xxxxxx/ Version History: v3: - Modify the atomic_get_input_bus_fmts to return the MEDIA_BUS_FMT_RGB121212_1X36 as default format.along as tidss currently supports only this format. v2: - Remove the Add output bus format negotiation patch from the series, as we use ouput format as MEDIA_BUS_FMT_FIXED and that is the default value if atomic_get_output_bus_fmts function is not implemented. - Return NULL if output format is not MEDIA_BUS_FMT_FIXED. - Return the supported color formats based on the display info structure.
