Create separate YAML schema for MDSS devicesd$ (both for MDP5 and DPU
devices). Cleanup DPU schema files, so that they do not contain schema
for both MDSS and DPU nodes. Apply misc small fixes to the DPU schema
afterwards. Add schema for the MDSS and DPU on sm8250 platform.
Changes since v5:
- Dropped the core clock from mdss.yaml. It will be handled in a
separate patchset together with adding the clock itself.
- Fixed a typo in two commit subjects (mdm -> msm).
Changes since v4:
- Created separate mdss-common.yaml
- Rather than squashing everything into mdss.yaml, create individual
schema files for MDSS devices.
Changes since v3:
- Changed mdss->(dpu, dsi, etc.) relationship into the tight binding
depending on the mdss compatible string.
- Added sm8250 dpu schema and added qcom,sm8250-mdss to mdss.yaml
Changes since v2:
- Added a patch to allow opp-table under the dpu* nodes.
- Removed the c&p issue which allowed the @0 nodes under the MDSS
device node.
Changes since v1:
- Renamed DPU device nodes from mdp@ to display-controller@
- Described removal of mistakenly mentioned "lut" clock
- Switched mdss.yaml to use $ref instead of fixing compatible strings
- Dropped mdp-opp-table description (renamed by Krzysztof in his
patchset)
- Reworked DPU's ports definitions. Dropped description of individual
ports, left only /ports $ref and description in dpu-common.yaml.

Split Mobile Display SubSystem (MDSS) root node bindings to the separate
yaml file. Changes to the existing (txt) schema:
- Added optional "vbif_nrt_phys" region used by msm8996
- Made "bus" and "vsync" clocks optional (they are not used by some
platforms)
- Added (optional) "core" clock added recently to the mdss driver
- Added optional resets property referencing MDSS reset
- Defined child nodes pointing to corresponding reference schema.
- Dropped the "lut" clock. It was added to the schema by mistake (it is
a part of mdp4 schema, not the mdss).

Add gcc-bus clock required for the SDM845 DPU device tree node. This
change was made in the commit 111c52854102 ("arm64: dts: qcom: sdm845:
move bus clock to mdp node for sdm845 target"), but was not reflected in
the schema.

Move properties common to all DPU DT nodes to the dpu-common.yaml.
Note, this removes description of individual DPU port@ nodes. However
such definitions add no additional value. The reg values do not
correspond to hardware INTF indices. The driver discovers and binds
these ports not paying any care for the order of these items. Thus just
leave the reference to graph.yaml#/properties/ports and the description.

Move properties common to all MDSS DT nodes to the mdss-common.yaml.
This extends qcom,msm8998-mdss schema to allow interconnect nodes, which
will be added later, once msm8998 gains interconnect support.

Move properties common to all MDSS DT nodes to the mdss-common.yaml.
This extends qcom,msm8998-mdss schema to allow interconnect nodes, which
will be added later, once msm8998 gains interconnect support.

Haven't we been over this already?
You have to define 'port' nodes or else anything is allowed in them
(and endpoint nodes). If you want to define them as pattern, then fine.
But you must have a ref to graph.yaml#/properties/port.

Last time you asked to do this, I did a check. Adding any additional
property results in a schema error. And this is logical.
graph.yaml#/properties/ports already limits the node properties. I
thus do not see a need to define port@[0-9a-f]+$. Did I miss anything?

You have now schema for qcom,sc7180-dpu so just reference it here instead.

OTOH, I think it fits your other uses, so it's ok.

I don't think I said. I thought about it some, as yes, we normally have
done as you suggested. The downside is with a ref we'll do the whole
validation of the child node twice (unless the referenced schema has a
'select: false') whereas here only 'compatible' is validated twice. This
way also complicates checking for unevaluatedProperties/additionalProperties.
So maybe better to keep with the 'normal' way and make this a ref.

Well.. I tried using $ref in the previous iteration, but then I faced
the fact that I can not use it. Using the $ref the node gets validated
even if it is disabled, and we do not want to do this. The nodes are
usually split in way that regulators are specified in the board DT file.
Thus disabled dsi/dsi-phy nodes do not get all the required regulators.
And dt-validate happily dumps tons of warnings for disabled nodes. Thus
I ended up with the compatible rather than $ref.

Only warnings about required properties? Those are supposed to get
filtered out if the node is disabled. Maybe being in a $ref doesn't
work.

Only warnings about required properties? Those are supposed to get
filtered out if the node is disabled. Maybe being in a $ref doesn't
work.

This seems to break regardless it is in $ref or when you directly
reference the schema.
I tested display/msm/dpu-sc7180.yaml on modified DTB when a required
property is missing (I removed reg-names) and:
1. When node is enabled:
c7180-idp.dtb: display-controller@ae01000: 'reg-names' is a required
property
Documentation/devicetree/bindings/display/msm/dpu-sc7180.yaml
rch/arm64/boot/dts/qcom/sc7180-idp.dtb: display-controller@ae01000:
Unevaluated properties are not allowed ('interrupt-parent',
'interrupts', 'operating-points-v2', 'opp-table', 'ports',
'power-domains' were unexpected)
2. When node is disabled the first error disappears (so no clue which
one is missing) but schema does not pass:
qcom/sc7180-idp.dtb: display-controller@ae01000: Unevaluated properties
are not allowed ('interrupt-parent', 'interrupts',
'operating-points-v2', 'opp-table', 'ports', 'power-domains' were
unexpected)
From schema: Documentation/devicetree/bindings/display/msm/dpu-sc7180.yaml
However I think there is no such problem, as Dmitry said, that ref
changes anything. There will be always failure - either from parent
schema (using $ref) or from device child schema (the one which actually
misses the property).
Best regards,
Krzysztof

Initially I stumbled upon this issue with the dsi and dsi_phy nodes
for msm8996 devices. If I have $ref here, dsi1/dsi1_phy nodes will
emit warnings regarding the missing -supply properties despite nodes
being disabled. If I use `compatible' here, the schema checks pass.
Thus I'd prefer to leave `compatible' here. Not to mention that it
also allows specifying a tighter binding than just using the $ref.

I don't think we understood each other. I claim that error will be there
anyway, just from different schema. So your change fixes nothing in
total schema check...

If the node is disabled, there will be no different schema check.

If the node is disabled, there will be no different schema check.

The following results were captured with the following command, with
most of the DSI and MDSS schema files fixed, using the following
command:
$ PATH=~/.local/bin/:$PATH make -C ../build-64/ ARCH=arm64
qcom/sda660-inforce-ifc6560.dtb CHECK_DTBS=y
DT_SCHEMA_FILES=display/msm
As you can see from the example below, when using 'compatible' I'm
getting warnings just for the gpu@5000000 node, while using $ref I
also got warnings for the dsi-phy@c996400 node (disabled in the DT
file).

I did not say anything about msm-mdss. I said you will get errors from
child schema anyway.
From schema:
/home/krzk/dev/linux/linux/Documentation/devicetree/bindings/display/msm/dsi-controller-main.yaml
/home/krzk/dev/linux/linux/out/arch/arm64/boot/dts/qcom/sda660-inforce-ifc6560.dtb:
dsi@c994000: clock-names: ['mdp_core', 'byte', 'byte_intf', 'mnoc',
'iface', 'bus', 'core_mmss', 'pixel', 'core'] is too long
From schema:
/home/krzk/dev/linux/linux/Documentation/devicetree/bindings/display/msm/dsi-controller-main.yaml
/home/krzk/dev/linux/linux/out/arch/arm64/boot/dts/qcom/sda660-inforce-ifc6560.dtb:
dsi@c994000: 'vdda-supply' does not match any of the regexes:
'pinctrl-[0-9]+'
If your child schema fails, the referencing schema fails as well...

I did not say anything about msm-mdss. I said you will get errors from
child schema anyway.
From schema:
/home/krzk/dev/linux/linux/Documentation/devicetree/bindings/display/msm/dsi-controller-main.yaml
/home/krzk/dev/linux/linux/out/arch/arm64/boot/dts/qcom/sda660-inforce-ifc6560.dtb:
dsi@c994000: clock-names: ['mdp_core', 'byte', 'byte_intf', 'mnoc',
'iface', 'bus', 'core_mmss', 'pixel', 'core'] is too long
From schema:
/home/krzk/dev/linux/linux/Documentation/devicetree/bindings/display/msm/dsi-controller-main.yaml
/home/krzk/dev/linux/linux/out/arch/arm64/boot/dts/qcom/sda660-inforce-ifc6560.dtb:
dsi@c994000: 'vdda-supply' does not match any of the regexes:
'pinctrl-[0-9]+'
If your child schema fails, the referencing schema fails as well...
Best regards,
Krzysztof

Although now with DSI-PHY I cannot reproduce it and I am pretty sure I
reproduced it with DPU controllers after modifying the DTS to lack a
property... Hmmm

Thanks for the quick fix!
However I think I'd still stick to the compatible binding for two reasons:
- It doesn't evaluate schema twice for these nodes
- It allows us to tightly link child nodes with the parent compatible,
which I think, was one of the points raised several revisions ago.

I see, what I did miss now. I missed adding properties to individual
/port nodes. Please excuse me. BTW: is there any reason for not
enforcing this in the graph.yaml?
