Subject: [PATCH v4 0/4] pwm support for allwinner sun8i R40/V40/T3 SOCs.

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

hao_zhang (4):
  dt-bindings: pwm: binding allwinner R40, V40, T3
  ARM: PWM: add allwinner sun8i R40/V40/T3 pwm support.
  ARM: dts: add pwm node for r40.
  ARM: pinctrl: sunxi-pinctrl: fix pin funtion can not be match
    correctly.
