I'm still waiting for an official Application Note from TI for the am57xx, but the short answer, don't touch the pinmux registers from linux. > What is the fastest way to read/write to the GPIO on the am57xx? Define them in the device tree, toggle them from userspace, just like the am335x, just don't TOUCH the pinmux...
