According to the latest datasheet, H3 has single PWM channel. H3 PWM controller has same register layout as sun4i driver, so it works by adding H3 specific data. And the second PWM channel is not supported, so the pinctrl function is removed.
Datasheet: http://linux-sunxi.org/File:Allwinner_H3_Datasheet_V1.2.pdf
Test environment: Tested on Nano Pi M1 board, but PA5 pin is assigned for UART0. So the debug console should be changed to other port like UART1.
Ex) aliases { serial0 = &uart1; };
&uart1 { pinctrl-names = "default"; pinctrl-0 = <&uart1_pins_a>; status = "okay"; };
v2: Split v1 patch-set into several patches
