#1709209 — [PATCH v3 00/13] Support more devices on rockchip rv1108

This series try to support i2c/spi/pwm/saradc/pmic/watchdog
on rockchip rv1108 soc.

As the clk tree part has been taken from Elaine's series, so
this part will be not included in my series from this version.

This version has no more changes, except the pwm  dt-bindings
followed by Rob's suggestion, and the Acked-by from Rob of other
dt-bindings.

Changes in v3:
- remove the clk tree part
- make the compatible string be: "rockchip,rv1108-pwm", "rockchip,rk3288-pwm"
  for rv1108 pwm

Changes in v2:
- add compatible string "rockchip,rv1108-pwm"
- add compatible string "rockchip,rv1108-saradc"

I don't care super much, but why don't you reuse rk3399_soc_data()?
Or even use the rk3399 compatible as fallback value?

Kind regards,

What do you need the io-channel-ranges for?
I.e. according to the documenation it is meant for when the adc is also
a "bus node" and has children that should inherit channels from it.

In all saradc uses so far we only have separate nodes referencing the
adc controller (like adc-keys etc), so this does not look like it is needed?

     Sorry, I just copied it from the downstream dts. After checked with 
David, he suggested that we could remove it.
