1 Device-Tree bindings for tilcdc DRM driver
4 - compatible: value should be one of the following:
5 - "ti,am33xx-tilcdc" for AM335x based boards
6 - "ti,da850-tilcdc" for DA850/AM18x/OMAP-L138 based boards
7 - interrupts: the interrupt number
8 - reg: base address and size of the LCDC device
10 Recommended properties:
11 - interrupt-parent: the phandle for the interrupt controller that
12 services interrupts for this device.
13 - ti,hwmods: Name of the hwmod associated to the LCDC
16 - max-bandwidth: The maximum pixels per second that the memory
17 interface / lcd controller combination can sustain
18 - max-width: The maximum horizontal pixel width supported by
20 - max-pixelclock: The maximum pixel clock that can be supported
21 by the lcd controller in KHz.
22 - blue-and-red-wiring: Recognized values "straight" or "crossed".
23 This property deals with the LCDC revision 2 (found on AM335x)
25 - "straight" indicates normal wiring that supports RGB565,
26 BGR888, and XBGR8888 color formats.
27 - "crossed" indicates wiring that has blue and red wires
28 crossed. This setup supports BGR565, RGB888 and XRGB8888
30 - If the property is not present or its value is not recognized
31 the legacy mode is assumed. This configuration supports RGB565,
32 RGB888 and XRGB8888 formats. However, depending on wiring, the red
33 and blue colors are swapped in either 16 or 24-bit color modes.
37 - port/ports: to describe a connection to an external encoder. The
38 binding follows Documentation/devicetree/bindings/graph.txt and
39 suppors a single port with a single endpoint.
41 - See also Documentation/devicetree/bindings/display/tilcdc/panel.txt and
42 Documentation/devicetree/bindings/display/tilcdc/tfp410.txt for connecting
43 tfp410 DVI encoder or lcd panel to lcdc
45 [1] There is an errata about AM335x color wiring. For 16-bit color mode
46 the wires work as they should (LCD_DATA[0:4] is for Blue[3:7]),
47 but for 24 bit color modes the wiring of blue and red components is
48 crossed and LCD_DATA[0:4] is for Red[3:7] and LCD_DATA[11:15] is
49 for Blue[3-7]. For more details see section 3.1.1 in AM335x
