We're currently working through a modified design based off of the AM335X starter kit. In our current setup, we need to use the pin that is currently labelled on the schematic as AM335X_LCD_DISEN.
Going through the board-am335xevm.c and mux33xx.c file, I can't find any reference to this pin (as it's labeled on the schematic). I've found the GPIO1_28 pin in the mux33xx.c file, but it seems to be declared in the board file as part of MMC2. This makes me wonder, is this pin necessary? Is it being used at all? It seems like in the current AM335X SK the LCD is always on, so my guess is that the pin is set on startup and never changed.
At this point I'm trying to find out if I've missed anything. Is this pin just declared in a funny way? Is it declared at all? Is it being used for something else?
Thanks for any assistance.
