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 Milo Kim (4): ARM: dts: sun8i: Add PWM pin in H3 ARM: dts: sun8i: Add PWM controller node in H3 pinctrl: sunxi: Remove unsupported PWM channel pinmux in H3 pwm: sunxi: Add H3 support Documentation/devicetree/bindings/pwm/pwm-sun4i.txt | 1 + arch/arm/boot/dts/sun8i-h3.dtsi | 15 +++++++++++++++ drivers/pinctrl/sunxi/pinctrl-sun8i-h3.c | 1 - drivers/pwm/pwm-sun4i.c | 9 +++++++++ 4 files changed, 25 insertions(+), 1 deletion(-) -- 2.9.3 -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
