Hi, NXP (freescale) support expert,

I try to light my lvds panel by a wandboard solo board, I edit the dts and get the error " ldb ldb.13: crtc not specified or invalid",

I think the reason is i place the script: crtcs = <0xf 0x0>; i think it is not correct ,so pls tell me how to write it, looking forward to reply, thanks.

my dts is the following, :

	fb@0 {
	compatible = "fsl,mxc_sdc_fb";
	disp_dev = "ldb";
	interface_pix_fmt = "RGB24";
	mode_str = "LP101WH4-SLAA";
	default_bpp = <0x20>;
	int_clk = <0x0>;
	late_init = <0x0>;
	status = "okay";

    };

		ldb@020e0008 {
			#address-cells = <0x1>;
			#size-cells = <0x0>;
			gpr = <0xa>;
			status = "okay";
			compatible = "fsl,imx6dl-ldb", "fsl,imx53-ldb";
			clocks = <0x2 0x87 0x2 0x88 0x2 0x27 0x2 0x28 0x2 0x29 0x2 0xb8 0x2 0xb9 0x2 0xd1 0x2 0xd2 0x2 0xd3 0x2 0xd4>;
			clock-names = "ldb_di0", "ldb_di1", "di0_sel", "di1_sel", "di2_sel", "ldb_di0_div_3_5", "ldb_di1_div_3_5", "ldb_di0_div_7", "ldb_di1_div_7", "ldb_di0_div_sel", "ldb_di1_div_sel";

			lvds-channel@0 {
				reg = <0x0>;
				status = "okay";
				crtcs = <0xf 0x0>;
				fsl,data-mapping = "spwg";
				fsl,data-width = <0x18>;

				display-timings {
					native-mode = <0x10>;

					LP101WH4-SLAA {
						clock-frequency = <0x44aa200>;
						hactive = <0x556>;
						vactive = <0x300>;
						hfront-porch = <0x50>;
						hback-porch = <0x30>;
						hsync-len = <0x20>;
						vback-porch = <0xe>;
						vfront-porch = <0x3>;
						vsync-len = <0x5>;
						hsync-active = <0x0>;
						vsync-active = <0x0>;
						linux,phandle = <0x10>;
						phandle = <0x10>;
					};
				};
			};

			lvds-channel@1 {
				reg = <0x1>;
				status = "disabled";
			};

Hi wz

one can look at "crtcs" linux documentation and example:

http://git.freescale.com/git/cgit.cgi/imx/linux-2.6-imx.git/tree/arch/arm/boot/dts/imx6dl-sabresd.dt...

http://git.freescale.com/git/cgit.cgi/imx/linux-2.6-imx.git/tree/Documentation/devicetree/bindings/s...

Best regards

igor
