The Timer Pulse Unit (TPU) is a 4-channels 16-bit timer used to generate waveforms. This driver exposes PWM functions through the PWM API for other drivers to use. The code is loosely based on the leds-renesas-tpu driver by Magnus Damm and the TPU PWM driver shipped in the Armadillo EVA 800 kernel sources.
