I have LVDS working on apq8064, but it requires fixes in the MMCC driver, in the MDP4 driver and in DTS. I need to clean up them first before even attempting to send them out. Also a PWM/LPG driver would help as otherwise the power supply is quick to be overloaded by the backlight. Nevertheless, LVDS/LCDC-only MDP4 is a valid usecase, but it has to be handled in the driver rather than in the core lib. -- With best wishes Dmitry
