   1 Device-Tree bindings for tilcdc DRM driver
   2
   3 Required properties:
   4  - compatible: value should be "ti,am33xx-tilcdc".
   5  - interrupts: the interrupt number
   6  - reg: base address and size of the LCDC device
   7
   8 Recommended properties:
   9  - interrupt-parent: the phandle for the interrupt controller that
  10    services interrupts for this device.
  11  - ti,hwmods: Name of the hwmod associated to the LCDC
  12
  13 Optional properties:
  14  - max-bandwidth: The maximum pixels per second that the memory
  15    interface / lcd controller combination can sustain
  16  - max-width: The maximum horizontal pixel width supported by
  17    the lcd controller.
  18  - max-pixelclock: The maximum pixel clock that can be supported
  19    by the lcd controller in KHz.
  20
  21 Optional nodes:
  22
  23  - port/ports: to describe a connection to an external encoder. The
  24    binding follows Documentation/devicetree/bindings/graph.txt and
  25    suppors a single port with a single endpoint.
  26
  27  - See also Documentation/devicetree/bindings/display/tilcdc/panel.txt and
  28    Documentation/devicetree/bindings/display/tilcdc/tfp410.txt for connecting
  29    tfp410 DVI encoder or lcd panel to lcdc
