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"; |

};
