The HDLCD is an RGB streamer that reads the data from a framebuffer and sends it to a single digital encoder (DVI or HDMI). properties: compatible: const: arm,hdlcd reg: maxItems: 1 interrupts: maxItems: 1 clock-names: const: pxlclk clocks: maxItems: 1 description: The input reference for the pixel clock. memory-region: maxItems: 1 description: Phandle to a node describing memory to be used for the framebuffer.
