Yes, I have. It's Nano Pi M1 which was derived from Orange Pi PC.
The board DTS is ready to be sent out, but I'm not sure which is better.

	a) Send new board DTS file in other patch thread

	[PATCH v3 0/4] Add PWM feature in Allwinner H3
	[PATCH v3 1/4] ARM: dts: sun8i: Add PWM pin in H3
	..
	[PATCH v3 4/4] pwm: sunxi: Add H3 support

	[PATCH] ARM: dts: sun8i: Add Nano Pi M1 support

Or

	b) Include the DTS in next patch-set v3
	[PATCH v3 0/4] Add PWM feature in Allwinner H3
	[PATCH v3 1/4] ARM: dts: sun8i: Add PWM pin in H3
	[PATCH v3 2/4] ARM: dts: sun8i: Add PWM controller node in H3
	[PATCH v3 3/4] ARM: dts: sun8i: Add Nano Pi M1 support
	...

I'd like to have your opinion.

Best regards,
Milo
