[PATCH v2 01/10] dt-bindings: pwm: allwinner,sun4i-a10: Add F1C100s compatible

[Andre Przywara]

The PWM controller in the Allwinner F1C100s series of SoCs is the same
as in the A20 SoCs, so allow using that as the fallback name.

Join the V3s compatible string in an enum on the way.

[PATCH v2 02/10] ARM: dts: suniv: f1c100s: add PWM node

[Andre Przywara]

The Allwinner F1C100s family of SoCs contain a PWM controller compatible
to the one used in the A20 chip.
Add the DT node so that any users can simply enable it in their board
DT.

I checked "by hand" that this matches the modified binding in patch
01/10. 

Reviewed-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de>

I assume the whole series will go in via a tree different from the PWM
tree? While this is Thierry's area of maintenance, I'd be surprised if
he had concerns about that.

Best regards
Uwe

Yeah, it's probably best for the Allwinner maintainers to pick this up
into their tree so that the bindings changes go along with the DT
changes.

Yeah, that's the plan. I'll merge it in following days.
