Daniel Mack 31e1391af2 video: fbdev: pxafb: Add support for lcd-supply regulator
Optionally obtain a lcd-supply regulator during probe and use it in
__pxafb_lcd_power() to switch the power supply of LCD panels.

This helps boards booted from DT to control such voltages without
callbacks.

PXA LCD Controller
------------------
Required properties:
- compatible : one of these
"marvell,pxa2xx-lcdc",
"marvell,pxa270-lcdc",
"marvell,pxa300-lcdc"
- reg : should contain 1 register range (address and length).
- interrupts : framebuffer controller interrupt.
- clocks: phandle to input clocks
Optional properties:
- lcd-supply: A phandle to a power regulator that controls the LCD voltage.
Required nodes:
- port: connection to the LCD panel (see video-interfaces.txt)
This node must have its properties bus-width and remote-endpoint set.
If the panel is not a TFT color panel, then a "lcd-type" property in
the panel should specify the panel type.
This panel node should be in the board dts.
Example:
lcd-controller@40500000 {
compatible = "marvell,pxa2xx-lcdc";
reg = <0x44000000 0x10000>;
interrupts = <17>;
clocks = <&clks CLK_LCD>;
port {
lcdc_out: endpoint {
remote-endpoint = <&panel_in>;
bus-width = <16>;
};
};
};
