Adding support for max-pixelclock and max-width device tree entries. As some devices that use the tilcdc hardware module have restrictions on the allowed/tested values. Also update DT bindings document to reflect new parameters.

Device-Tree bindings for tilcdc DRM driver
|
|
|
|
Required properties:
|
|
- compatible: value should be "ti,am33xx-tilcdc".
|
|
- interrupts: the interrupt number
|
|
- reg: base address and size of the LCDC device
|
|
|
|
Recommended properties:
|
|
- interrupt-parent: the phandle for the interrupt controller that
|
|
services interrupts for this device.
|
|
- ti,hwmods: Name of the hwmod associated to the LCDC
|
|
|
|
Optional properties:
|
|
- max-bandwidth: The maximum pixels per second that the memory
|
|
interface / lcd controller combination can sustain
|
|
- max-width: The maximum horizontal pixel width supported by
|
|
the lcd controller.
|
|
- max-pixelclock: The maximum pixel clock that can be supported
|
|
by the lcd controller in KHz.
|
|
|
|
Example:
|
|
|
|
fb: fb@4830e000 {
|
|
compatible = "ti,am33xx-tilcdc";
|
|
reg = <0x4830e000 0x1000>;
|
|
interrupt-parent = <&intc>;
|
|
interrupts = <36>;
|
|
ti,hwmods = "lcdc";
|
|
};
