[PATCH 0/4] Enable pwm support for IPQ5332 & IPQ9574 SoCs

[PATCH 0/4] Enable pwm support for IPQ5332 & IPQ9574 SoCs

[Devi Priya]

Enable pwm support for IPQ5332 & IPQ9574 SoCs and document the
pwm compatibles.
While at it, use qcom,ipq6018-pwm as the fallback compatible and extend the
simple-mfd support for ipq5332 & ipq9574 targets.

This series depends on the below series which adds support
for the PWM driver on IPQ targets:

Given this dependency, I suggest you add the patches from this series to
the next revision of the IPQ base series.

I've kept this series in my inbox, hoping that you would work out the DT
bindings with the maintainers. Dropping them now, please resend the DTS
patches once the bindings are in order.
