2015-05-19	pwm: img: Impose upper and lower timebase steps value	Naidu Tellapati
	The PWM hardware on Pistachio platform has a maximum timebase steps value to 255. To fix it, let's introduce a compatible-specific data structure to contain the SoC-specific details and use it to specify a maximum timebase. Also, let's limit the minimum timebase to 16 steps, to allow a sane range of duty cycle steps.

2015-01-30	pwm: Imagination Technologies PWM DAC driver	Naidu Tellapati
	The Pistachio SOC from Imagination Technologies includes a Pulse Width Modulation DAC which produces 1 to 4 digital bit-outputs which represent digital waveforms. These PWM outputs are primarily in charge of controlling backlight LED devices.
