Subject: [PATCH v2 1/2] dt-bindings: display: bridge: Add NXP i.MX93 parallel display format configuration
NXP i.MX93 mediamix blk-ctrl contains one DISPLAY_MUX register which
configures parallel display format by using the "PARALLEL_DISP_FORMAT"
field. Add device tree bindings for the display format configuration.
