Hi Simon,

I am trying to coverting mxsfb.c to support dm.

But met the following issue.
"
mxsfb_lcd_bind: Frame buffer size 200400
Video device 'lcdif at 021c8000' cannot allocate frame buffer memory -ensure the device is set up before relocation
"

I add "u-boot, dm-pre-reloc" in dts as the following, but no help.

&lcdif {
	pinctrl-names = "default";
	pinctrl-0 = <&pinctrl_lcdif_dat
		     &pinctrl_lcdif_ctrl
		     &pinctrl_lcdif_reset>;
	display = <&display0>;
	status = "okay";
	u-boot,dm-pre-reloc;

	display0: display {
		bits-per-pixel = <16>;
		bus-width = <24>;
		u-boot,dm-pre-reloc;
		status = "okay";

		display-timings {
			native-mode = <&timing0>;
			u-boot,dm-pre-reloc;
			timing0: timing0 {
			u-boot,dm-pre-reloc;
			clock-frequency = <9200000>;
			hactive = <480>;
			vactive = <272>;
			hfront-porch = <8>;
			hback-porch = <4>;
			hsync-len = <41>;
			vback-porch = <2>;
			vfront-porch = <4>;
			vsync-len = <10>;

			hsync-active = <0>;
			vsync-active = <0>;
			de-active = <1>;
			pixelclk-active = <0>;
			};
		};
	};
};
