Convert all the 'simple' panels which either use the single
'power-supply' property or don't say and just reference
simple-panel.txt. In the later case, bindings are clear as to which
properties are required or unused.

We could perhaps consolidate a bunch of these, but I have no idea how 
accurate some of these are WRT what's required or not. Seems strange 
that 'backlight' is optional unless the backlight is tied full on for 
example. If that's the case, then should backlight ever be required?

Hi Rob.

Thanks for doing this boring, trivial and tiresome task.

So Thierry and I ended up as Maintianes for them all.
I gues thats OK as we look after the panel stuff anyway.

I do not really follow you here.
Looking through the patch set things looks normal to me.

What do I miss here?


I did not find anything I consider bugs. It is mostly small
inconsistencies.

- Almost all new .yaml files ends with "..."
  Except one file: nec,nl12880b20-05.yaml


- When there is more than one compatible the extra compatible is specified
  in two ways:

  Like this with consts:
    properties:
    +  compatible:
    +    items:
    +      - const: bananapi,lhr050h41
    +      - const: ilitek,ili9881c
    +

  Link this with enum:
    +properties:
    +  compatible:
    +    enum:
    +      - urt,umsh-8596md-t
    +      - urt,umsh-8596md-1t
    +      - urt,umsh-8596md-7t
    +      - urt,umsh-8596md-11t
    +      - urt,umsh-8596md-19t
    +      - urt,umsh-8596md-20t

- My OCD prefer only one method to list more than
  one compatible. Using "enum" syntax above seems to be the common
  case - and the simple syntax.

- In several cases the original binding provided an example
  which is now dropped. Is this on purpose?
  This is very simple examples - so I am happy to see them go.
  They really did not provide anything extra.
  I have mentioned it for some - but I stopped as I think
  they are left out on purpose.
  The changelog should mention this.

- There are some bindings that list a reg property.
  I have noted that their comment is not keept.

- It seems inconsistent what is listed as properties and mandatory.
  Most, but not all, include "enable-gpios: true" in properties.
  And the listed mandatory properties sometimes
  differ even when the description does not give a hint why.
  Maybe this was needed to verify existing bindings?

See a few comments in the following.

	Sam

This looks like an unrelated change - drop?

This comment is lost. It does not provide much info so the value of the

The binding for nec,nl4827hc19-05b.txt should list the original
maintainers:
M:      Stefan Agner <stefan@agner.ch>
M:      Alison Wang <alison.wang@nxp.com>


I did not check all - but the files I checked did not have an explicit

It was somewhat scripted at least...

I'm saying a bunch of these could just be a single schema doc with a
long list of compatibles. The variation is in what properties are
required or not.

This means 'compatible' must have 2 strings in the order specified.

This means 'compatible' is a single string of one of the above.

Okay.

These are all DSI panels. Linus' DSI controller binding defines what
'reg' is, so I prefer not duplicating that everywhere.

That's partly what my comment above on 'backlight' was about. I don't
really know what's just copy-n-paste inconsistencies vs. actual h/w
differences.

I just maintained what was documented before and haven't checked each
one against usage in in-tree dts files. This is why I've tried to
enforce that folks list which 'simple panel' properties they use.

For example, there's 3 cases for a panel with 'enable-gpios':
- No enable input
- Enable input line is tied off to active state
- Enable input line is connected to GPIO

What's written for the binding probably depends on the board design
the person writing the binding is using. Arguably, 'enable-gpios'
should always be optional because of the 2nd case unless the h/w
always needs s/w control of the enable line.

It's not because the example starts failing when the schema validates
it. I can split it out though if you prefer.

It would be just wonderful if we could have only a few
dt-bindings for the simple panels.
Like you I cannot see why enable-gpios should be required.

We could end up with something like three classes of bindings:

+required:
+  - compatible
+  - power-supply

+required:
+  - compatible
+  - port
+  - power-supply

+required:
+  - backlight
+  - compatible
+  - port
+  - power-supply

The port part is to my best understanding a way to
connect the panel to the display driver.
So it should be more how the connect in the binding
that decides if port is used or not.
And the panel should not require it.

I may use it with display drivers that do not support it
in their binding.

And then we have backlight - which can hardly be mandatory.
The panel could hard-wire it to provide backligt if it wanted
and the binding should continue to work.
I think you had the same argument.

So we are down to two required properties:
+required:
+  - compatible
+  - power-supply

Could we put all simple panels in one binding file
with only this - that would be great.
Hopefully scripted somehow...

Then adding new simple panels would be a matter of
adding a new compatible.
And if they are sorted this should not cause many merge issues either.

I hope I understood you correct.

Yes, though it's also initially panels were just the child of the
controller before 'port' came along. We still allow both ways though
'port' is preferred.

Yes. The issue would be enforcing the big disclaimer of "Do not add
your panel here unless it has a single power rail." (And anything else
we think of). Between a single line add vs. a whole new doc, you know
what people will pick. I guess panels could still be moved out of the
common doc later on. We'd also have to be fighting off the "let me add
just one new property for my panel".

You did. I'd like to hear Thierry's thoughts on this before going down
this path.

If the panel cannot be supported by the panel-simple driver then
this is a good sign that it does not belong in the bindings file.
Or something like this.

I do not see it as a 1:1 for all panels but I guess most panels
supported by panel-simple would go in a single bindings file.

Seconded, Thierry?
