Subject: [PATCH v4 0/4] pwm support for allwinner sun8i R40/V40/T3 SOCs.
Date: Wed, 13 Dec 2017 22:38:40 +0800 [thread overview]
Message-ID: <20171213143840.GA17754@arx-s1> (raw)
This patchset add pwm support for allwinner sun8i R40/V40/T3 SOCs.
all has been teat on T3 board.
Some features
8 PWM channels outputs(4 PWM pairs)
Supports capturing input
Supports three kinds of output waveforms: continuous waveform, pulse
waveform and complementarity pair
Programmable deadzone generator and controllable dead-time
0% to 100% adjustable duty cycle
Up to 24/100MHz output frequency
Minimum resolution is 1/65536
Supports interrupt for PWM output and capturing input
