Hi,
This patch series aims to add BOE EV121WXM-N10-1850 panel support
in the DRM simple panel driver.
Patch 1/2 adds dt-bindings support for the panel.
Patch 2/2 adds the panel support in the DRM simple panel driver.

NXP i.MX93 mediamix blk-ctrl contains one DISPLAY_MUX register which
configures parallel display format by using the "PARALLEL_DISP_FORMAT"
field. Add a DRM bridge driver to support the display format configuration.

With all previous preparations done to make it possible for the
single LCDIF embedded in i.MX93 SoC to drive multipledisplays
simultaneously, add i.MX93 LCDIF compatible string as the last
step of adding i.MX93 LCDIF support.
