Kunihiko Hayashi Nov. 29, 2022, 10:35 a.m. UTC 
  Add devicetree binding schema for the system controller implemented on
Socionext Uniphier SoCs.

This system controller has multiple functions such as clock control,
reset control, internal watchdog timer, thermal management, and so on.

As Rob's bot pointed, you need to update here examples in other
bindings, so they will pass. Otherwise it is not bisectable change.

All of them can have children or only some?

I've got it. I should also update other examples.

In case of this system controller,
all SoCs has clock-controller, reset-controller and watchdog.

However, some SoCs don't have thermal-sensor and
their register addresses are reserved.

What about this one? What SoC is this? Looks too generic.

It's the same one as soc-glue, so it should be placed as follows.

items:
   - enum:
       - ...
       - ...
   - const: socionext,uniphier-sysctrl

However, currently it is no use for now. I'll drop it.

Thank you,
