We'll connect a LCD panel.
In MX6DL_SABRE-SDP, there are the following control signals.
DI0_PIN2 => DISP0_HSYNCH
DI0_PIN3 => DISP0_VSYNCH
DI0_PIN4 => DISP0_CNTRST
DI0_PIN15 => DISP0_DRDY
These signals aren't explained in "Pin Assignments" of a reference manual(IMX6SDLRM.pdf).
However, in IOMUX tool, these signals are assigned to ALT1 mode.
Can these signals be used in ALT1 mode?
Or is the GPIO function used as these signals?
