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 DOC: https://github.com/tinalinux/docs/blob/r40-v1.y/Allwinner_R40_User_Manual_V1.0.pdf https://github.com/tinalinux/docs/blob/r40-v1.y/R40_Datasheet_V1.0.pdf Regards;-) Hao Zhang hao_zhang (4): dt-bindings: pwm: binding allwinner R40, V40, T3 ARM: PWM: add allwinner sun8i R40/V40/T3 pwm support.
