This can be:

clock-names:
  minItems: 1
  maxItems: 2
  items:
    - const: bus
    - const: mod

And the length should be checked based on the compatible value, with
something like

if:
  properties:
    compatible:
      contains:
        const: allwinner,sun50i-h6-ths

then:
  properties:
    clocks:
      maxItems: 1

    clock-names:
      maxItems: 1

else:
  properties:
    clocks:
      maxItems: 2

    clock-names:
      maxItems: 2

This should be checked using an if as well.

You can drop the items and just move the description up one level,
under nvmem-cells

Ditto for the const

Whether clocks, clock-names and resets are thereshould be check using
an if statement as well.

You don't need the label at all, and the node name should be
temperature-sensor according to the DT spec, not ths. This applies to
all you examples.

Additionally, minItems should be 0, since A83T doesn't have bus clock/reset. And
then there should be a special case for A83T too with min/maxItems = 0 for both
resets and clocks.

	o.

That's why I removed clocks, clock-names and resets from required
properties. If they're present min/maxItems should be 1 and 2
accordingly.

Sorry, I don't quite get it. What exactly do you want me to do with
this one? nvmem-cell-names must be "calibration"

Hey Yangtao,

I've already addressed all the comments and fixed patchset is sitting
in https://github.com/anarsoul/linux-2.6/tree/ths-5.4

I'll rebase and submit new version after merge window is closed (in ~1.5 weeks?)

Regards,
Vasily
