title: Freescale i.MX93 specific extensions to Synopsys Designware MIPI DSI

maintainers:

description: |
  There is a Synopsys Designware MIPI DSI Host Controller and a Synopsys
  Designware MIPI DPHY embedded in Freescale i.MX93 SoC.  Some configurations
  and extensions to them are controlled by i.MX93 media blk-ctrl.
