On the imx7d dev board, there is an EPD connector J13 that has i2c, interrupt, which seems like I could customize the device tree to talk to touch panels with a common FT5x16 6 pin interface. Seems overkill though to buy a 120 pin connector and use 6 of them. Is there a better way to bring those signals in and customize them during development?
I thought of using the I2C pins connected to the LCD 50 pin connector but there doesn't seem to be any pin available I could use as the interrupt. Anyone have a better way to solve this or is using J13 the best way to go?
