[PATCH v1 0/36] dt-bindings: display: convert remaning panel bindings to DT Schema

[PATCH v1 0/36] dt-bindings: display: convert remaning panel bindings to DT Schema

[Sam Ravnborg]

Convert remaining(*) panel bindings to DT Schema.

To prepare for the migration a few preparations
patches was required:

- te-gpios is now added to panel-common - as this
  property is used by a few bindings.

- The slave part of spi-controller.yaml was migrated to a
  new file spi-slave.yaml.
  This was done so spi slaves in panel/ could include
  this file rather than duplicate property names.
  => Please review this carefully!


The original author of the panel bindings are listed as maintainer
in the DT Schema. In the few cases the panel binding was also
listed in MAINTAINERS I checked that there was a match.
It was done manually so I may have missed someone.

All bindings pass dt_binding_check with no warnings.

- "dt-bindings: display: convert ilitek,ili9322 to DT"
  The .txt file listed some constrains that I did not manage
  to capture in the DT Schema.
  And some properties looks like that could be dropped.
  => Please take a closer look.

- "dt-bindings: display: convert sharp,lq101r1sx01 to DT Schema"  
  The .txt file describes some constrains, as some properties
  are mandatory for the main challen, but not allowed
  for the secondary channel.
  These constraints are not matched in the DT Schema.
  => Any hints how to do this would be appreciated.


Patches made on top of drm-misc-next as of today with no other patches.

(*) Two .txt files reamins:
- display-timing.txt, points to display-timings.yaml
- panel-dsi-cm.txt, conversion is included in another patch-set

[PATCH v1 01/36] dt-bindings: display: add te-gpios to panel-common

[Sam Ravnborg]

Several bindings specifies a "te-gpios" for tearing effect signal.
Add this to panel-common so we have a shared definition.

[PATCH v1 02/36] dt-bindings: spi: support non-spi bindings as SPI slaves

[Sam Ravnborg]

Independent bindings can be SPI slaves which for example is
the case for several panel bindings.

Move SPI slave properties to spi-slave.yaml so the independent
SPI slave bindings can include spi-slave.yaml rather than
duplicating the properties.

[PATCH v1 06/36] dt-bindings: display: convert ilitek, ili9322 to DT Schema

[Sam Ravnborg]

The .txt binding explains:

"
    The following optional properties only apply to
    RGB and YUV input modes and
    can be omitted for BT.656 input modes:
"

This constraint is not implmented in the DT Schema.

The original binding from the .txt file referenced
properties that is included in panel-timing.yaml.
These properties are kept here as we want as close to a 1:1
conversion as we can. If the properties should be dropped
from the binding then this is a follow-up patch.

The properties in question are:
  - pixelclk-active
  - de-active
  - hsync-active
  - vsync-active

[PATCH v1 09/36] dt-bindings: display: convert innolux, p079zca to DT Schema

[Sam Ravnborg]

As the binding matches panel-simple, added the compatible to the
panel-simple list.
With this change enable-gpios is now optional.

[PATCH v1 14/36] dt-bindings: display: convert kingdisplay, kd097d04 to DT Schema

[Sam Ravnborg]

kingdisplay,kd097d04 matches the panel-simple-dsi binding.
The only difference is that enable-gpios is now an optional
property.

[PATCH v1 27/36] dt-bindings: display: convert sitronix, st7701 to DT Schema

[Sam Ravnborg]

The old binding documented that a number of properties is
required only for a specific panel.
The binding supports only one panel so they are now
unconditionally required.

[PATCH v1 30/36] dt-bindings: display: convert sharp, ls043t1le01 to DT Schema

[Sam Ravnborg]

The txt binding specified the property "power-supply".
But the example and the actual implementation in the linux-kernel
uses "avdd-supply".
So the binding is adjusted to use avdd-supply as this seems
to be the correct choice.
There are no DT files in the linux kernel to check.

[PATCH v1 31/36] dt-bindings: display: convert sharp, lq101r1sx01 to DT Schema

[Sam Ravnborg]

This bindings describes a panel with a secondary channel.

A few of the properties are only required for the
main (non-secondary) node.
This is properly described in the binding.

A few properties are only valid for the main node,
this is not described in the binding.
I failed to find a way to describe it.

-Sharp Microelectronics 10.1" WQXGA TFT LCD panel

-This panel requires a dual-channel DSI host to operate. It supports two modes:
-- left-right: each channel drives the left or right half of the screen
-- even-odd: each channel drives the even or odd lines of the screen
-
-Each of the DSI channels controls a separate DSI peripheral. The peripheral
-driven by the first link (DSI-LINK1), left or even, is considered the primary

-to the peripheral driven by the second link (DSI-LINK2, right or odd).
-
-Note that in video mode the DSI-LINK1 interface always provides the left/even
-pixels and DSI-LINK2 always provides the right/odd pixels. In command mode it
-is possible to program either link to drive the left/even or right/odd pixels
-but for the sake of consistency this binding assumes that the same assignment
-is chosen as for video mode.
-
-Required properties:
-- compatible: should be "sharp,lq101r1sx01"
-- reg: DSI virtual channel of the peripheral
-
-Required properties (for DSI-LINK1 only):
-- link2: phandle to the DSI peripheral on the secondary link. Note that the

-  This pin is the RESB pin as specified in the LS037V7DW01.pdf file.
-- mode-gpios: a GPIO
-  ordered MO, LR, and UD as specified in the LS037V7DW01.pdf file.
-
-Required nodes:

To me it seems like you are creating the common SPI slave
bindings? Maybe the commit message should be about that.

255? Or am I wrong?

Apart from that it looks good to me.

Sorry about that. They should be dropped, but certainly it
is fine to do with a follow up patch.

I changed my mind - lets try to avoid too many patches.
So if you do not mind I will do it in this patch - and note it in the
changelog.

Isn't this also compatible with panel-simple bindings? 'label' is the only one not in panel-simple, 
but that's optional and has never been used by the panel driver.

The panel is a SPI slave - which is not too obvious from the old
binding.

The new DT Schema includes spi/spi-slave.yaml to give the binding
proper access to the spi slave properties.

That would not be possible with panel-simple binding as no further
properties are allowed with the panel-simple binding.

I hope this explains why there is a dedicated binding for this panel.

Hmm, but how is this different than, say, DSI panels? There are DSI panels in panel-simple bindings, 
and those might require DSI bus parameters ('reg' in the minimum).

We have panel-simple-dsi for DSI simple based panels.
This binding includes the reg property.

If we have included DSI panels in panel-simple.yaml, and we likely have
by accident, then they should be moved to panel-simple-dsi.yaml.

If they requires anything else then they shall have their
own binding.

panel-simple.yaml and panel-simple.dsi.yaml are on purpose
only for the simple panels and they have:
"additionalProperties: false" to avoid that a lot
of extra sneaks in.

I actually considered shortly a panel-simple-spi.yaml,
but the few panels I looked at had different names
for the power-supply so that did not fly.
I did not check them all - we have today (with this patch-set)
9 bindings that references spi-slave.yaml.

Okay, I understand now. Makes sense.

panel-simple.c has dsi_of_match, which lists DSI panels. I was looking at that when I said 
panel-simple binding has DSI panels. At least auo,b080uan01 and osddisplays,osd101t2045-53ts are 
there, and earlier in this series you moved osddisplays,osd101t2587-53ts to panel-simple bindings.

What is an "independent binding"?

Please submit patches using subject lines reflecting the style for the
subsystem, this makes it easier for people to identify relevant patches.
Look at what existing commits in the area you're changing are doing and
make sure your subject lines visually resemble what they're doing.
There's no need to resubmit to fix this alone.

Hi Mark.

For several panels we have device trees that looks like this:

spi {
    #address-cells = <1>;
    #size-cells = <0>;

    panel@0 {
        compatible = "kingdisplay,kd035g6-54nt";
        reg = <0>;

        spi-max-frequency = <3125000>;
        spi-3wire;
        spi-cs-high;
	...


The bindings are child of the spi controller node, but not specified
in the same binding file as the spi controller node.

A lot of bindings repeats the descriptions of (some of) the
pi-slave properties.
To avoid introducing yet another set of redundant and maybe incomplete
SPI slave property descriptions I moved the relevant properties
from spi-controller.yaml to spi-slave.yaml.

So SPI slaves can now reference spi-slave.yaml to get access to
the SPI slave properties - and the copies can be avoided.
Likewise spi-controller.yml now references spi-slave.yaml.

This was the best way I saw it could be done.

This approach is used in several bindings in this patch set.

So what you're trying to do is define a generic class for SPI slaves
which are just normal children of SPI nodes?  I really can't get to
there from your changelog so we need some work there - in particular
"non-spi bindings" is *very* confusing as as far as I can see these are
bindings for SPI devices.

Of course not, this how all buses work isn't it?

Rob didn't do the binding conversion but he did review it - I'm a bit
surprised that there's issues here?

Also shouldn't there be some constraint that these devices have to be
the child of a SPI controller or something?  Just including a file
doesn't look right for something like class definition.

For panels we have panel-common.yaml that list all the
typical properties used by a panel - so the individual
panel bindings shall not repeat them.
This is also aligned with the principle of re-using properties rather
than inventing new properties all over.

And with a number of bindings describing HW that is SPI slaves
the idea is to do something like we do for panels.

I look forward for Rob's feedback - but as he is on vacation this week
we may have to wait a week for that.

The simple way forward had been to do like we do in many other places
and include a few SPI properties and be done with it.
This is an attempt to do something better.
If there is push-back or a nack, then we can always do like we do in
other places and just duplicate the properties.

It was the best I could come up with - and this patch was called out
for review in the hope there is a better way than this patch.

We have similar examples like:
  - pincfg-node.yaml
  - regulatro.yaml
  - dma-common.yaml

They are not exactly 1:1 to what we do with spi-slave.yaml, but they
served as inspiration.

It definitely seems like a useful thing, just a bit surprised it's not
already there and if this is the best way to do it.

I'm curious what properties your consumers have for regulators - I'd
expect them to just have simple pointers to the regualtors with no
configuration.

I can see what you're trying to do, but you don't really need to.

All the SPI devices will be declared under a spi controller node that
will validate its child nodes (and thus the devices) already.

Doing it this way would actually make all the checks happen twice,
once as part of the SPI controller, once as part of the SPI device
binding, without any good reason.

This was the missing piece - thanks.
And as Mark put it "why is this suddenly an issue"?
Turns out this is already properly handled and I made up an issue.
Maybe Mark tried to explian it to me already...

I had focus on validating the example in the binding
file and not the full picture.

One thing I do not see properly addressed, but maybe I just miss it.
What triggers that we catch properties that are not supposed to be
present?

If we see a unsupported property "foobar":

spi {
    ...
    panel {
       ....
       foobar = <1>;
    };
};

somewhere in a SPI slave binding we should catch this.
If for no other reasons that it could be a simple spelling mistake
that otherwise could go undetected for a long time.
But maybe this is really not feasible to do?

Yeah, the schemas multi-layering thing is pretty difficult to get used

So you have multiple things here you can do.

Like I said, the schemas are all run as some kind of layers, and each
schema must validate, so you'll want to make a schema that will
validate only what's it supposed to be validating.

Let's use your SPI panel as an example. The SPI controller schema has
a description of what a controller is supposed to look like, and the
properties that are useful to that controller in the devices (things
like the chip-select number, phase settings, etc).

However, at the controller level, you have no idea what devices are
connected, and thus you cannot limit the number of properties a child
is going to have.

The second layer that comes in is the device binding itself. Here,
you'll know what the device itself needs, but you don't really care
about the SPI controller setting itself, since you could have pretty
much each combination in various DTs.

The main property to restrict the allowed properties is
additionalProperties, and setting it to false will raise an error for
each property encountered that isn't part of the *current*
schema. This means that we can't set it for the spi controller
binding, and we would need to duplicate the list of all the generic
SPI properties in each and every binding to avoid spurious error
messages: this is not really ideal, but some (early) schemas are doing
this.

The next spec of the schema language introduces a new property though
that is unevaluatedProperties, which works pretty much like
additionalProperties, but will emit an error only if no schema defines
it. Like I said, the library implementing the schema validation logic
doesn't implement that new spec yet, but the tools allow that property
to be set (but it's ignored). It would be best to simply use
unevaluatedProperties in your panel patch, and when the tools will be
updated you'll get the behaviour you want.

No, I didn't actually understand how it worked - I was just pretty sure
that it should and trusted that Rob and Maxime had got it right.

if:

then:
  not:
    required:
      - power-supply

Test that though as sometimes I still write crap for json-schema.

Uhhh, it's looking for dsi-controller(@.*)? which is not the common 
case found in dts files. We should fix that to dsi(@.*)?.

I've gone rather quickly thru the series. Other than what I commented 
on, the rest look fine generally. There may be a couple with similar 
comments.

Thanks.
Some of this was trivial stuff I should have fixed while converting -
great with an extra pair of eyes.

I will re-spin and try to spot similar issues in the other bindings when
I do so.

This binding can specify up to three GPIOs like this:


> > +        mode-gpios = <&gpio5 26 GPIO_ACTIVE_HIGH        /* gpio154, lcd MO */
> > +                      &gpio1 2 GPIO_ACTIVE_HIGH         /* gpio2, lcd LR */
> > +                      &gpio1 3 GPIO_ACTIVE_HIGH>;       /* gpio3, lcd UD */

They are in the linux kernel driver accessed like this:

    devm_gpiod_get_index(&pdev->dev, "mode", 2, GPIOD_OUT_LOW);

The following is OK in the DT file:

    mode-gpios = <&gpio5 26 GPIO_ACTIVE_HIGH>;

    mode-gpios = <&gpio5 26 GPIO_ACTIVE_HIGH
                  &gpio1 2 GPIO_ACTIVE_HIGH>;
		  
    mode-gpios = <&gpio5 26 GPIO_ACTIVE_HIGH
                  &gpio1 2 GPIO_ACTIVE_HIGH
                  &gpio1 3 GPIO_ACTIVE_HIGH>;

But the following is not OK:
    mode-gpios = <&gpio5 26 GPIO_ACTIVE_HIGH>, <&gpio1 2 GPIO_ACTIVE_HIGH>;

Any hints how to specify the binding to prevent the above?
I have tried a few combinations - but they do not catch this.
So my binding attempts are not restrictive enough.

Any hints how to describe this properly?

So it should be:

minItems: 1
maxItems: 3

With the above, the 2nd 2 should fail...

And this should pass. We want phandle+arg type properties to be
bracketed like this.

If that's not working, then it's a bug in the tooling. Please confirm
and I'll investigate.

OK, so if I get you right you say that we should accept the:
<phandle+arg>, <phandle+arg> ... syntax.

And then ignore that current DT files uses:
<phandle+arg phandle+arg>


A binding like this:
 mode-gpios:
    minItems: 1
    maxItems: 3
    description: |
      GPIO ordered MO, LR, and UD as specified in LS037V7DW01.pdf
      This panel can have zero to three GPIOs to configure to


Do not error out when the example looks like this:

        mode-gpios = <&gpio5 26 GPIO_ACTIVE_HIGH        /* gpio154, lcd MO */
                      &gpio1 2 GPIO_ACTIVE_HIGH         /* gpio2, lcd LR */
                      &gpio1 3 GPIO_ACTIVE_HIGH>;       /* gpio3, lcd UD */

So if I get you right this is a bug in the tooling.
I have updated the tooling a few days ago, should be on the latest.

In the actual example I go for the snip you see above.

That's because we can't distinguish between this and 1 entry as the
schema doesn't have visibility of what #gpio-cells value is. dtc does
check that the cell sizes are correct. We'll need to somehow combine
that and the schema to check this form correctly.

Limitation I guess. I thought you where saying the bracketed form was
not working.
