LCD not working on custom i.mx6q board

Question asked by jiaoka010 on Nov 6, 2013

Hi, I'm a newbie in Linux kernel. Recently I try to port a working kernel (3.0.68) to mainline kernel (3.12), but somehow the LCD is not working. By not working I mean the LCD doesn't display meaningful output but the backlight is on and I can see some artifacts on the screen. The LCD model is PM070WL4. I modified the dtsi files from Sabre SD dtsi because from what I understand, they use the same connection, so I just modify the LCD parameters in my dtsi. Is this correct? my I attach the old board.h and board.c files along with the dts and dtsi files.
