Sometime we power-on the device. LVDS panel is black and no infomation on LVDS panel.
Check the dmesg, there've "MXCFB_WAIT_FOR_VSYNC: timeout" message always repeate.
We've already disable "CONFIG_MX6_CLK_FOR_BOOTUI_TRANS" in kernel , but it seems no help.
Have any method to solve this problem ? Thanks!!
