// Package am335x exposes functionality for the Texas Instruments Sitara AM335x
// processor family.
//
// This processor family is found on the BeagleBone. PRU-ICSS functionality is
// implemented in package pru.
//
// The GPIO pins of the AM335x CPU are grouped into 3 groups of 32 pins: GPIO0,
// GPIO1, and GPIO2. The CPU documentation refers to GPIO in the form of
// GPIOx_y. To get the absolute number, as exposed by sysfs, use 32*x+y to get
// the absolute number.
