[PATCH v8 0/3] dt-bindings: net: can: convert three bindings to DT schema

[PATCH v8 0/3] dt-bindings: net: can: convert three bindings to DT schema

[Quchaosheng]

Three CAN controller bindings converted from free-form text to DT schema.

One series, one thread.

What changed since v7: v7 dropped the spi-peripheral-props.yaml reference
from holt,hi311x, on the grounds that the example does not use SPI
properties. That was wrong. The HI-3110 is an SPI peripheral, so its node
carries spi-max-frequency, and unevaluatedProperties: false rejects it
without the reference. dt_binding_check against a node carrying
spi-max-frequency fails without the reference and passes with it.

holt,hi311x is therefore back to exactly what Rob reviewed in v6. Only
patch 2/3 differs from v7; the other two are unchanged.

ifi,canfd-1.0
	Unchanged from v7.

holt,hi311x
	Restore the $ref to spi/spi-peripheral-props.yaml. Identical to v6 again.

fsl,mpc5xxx-mscan
	Unchanged from v7.

[PATCH v8 1/3] dt-bindings: net: can: ifi,canfd-1.0: Convert to DT schema

[Quchaosheng]

Convert the IFI CAN-FD controller binding from free-form text to DT
schema.

Reference can-controller.yaml. interrupts is required: the driver obtains
it with platform_get_irq().

The example now uses the GIC and irq header defines instead of raw numbers.
The values are unchanged: GIC_SPI is 0, IRQ_TYPE_NONE is 0 and 1 is
IRQ_TYPE_EDGE_RISING. Rename the example node from canfd to can so that it
matches the $nodename pattern in can-controller.yaml.

[PATCH v8 2/3] dt-bindings: net: can: holt,hi311x: Convert to DT schema

[Quchaosheng]

Convert the Holt HI-311X binding from free-form text to DT schema.

Reference can-controller.yaml and spi/spi-peripheral-props.yaml. The
HI-3110 sits on an SPI bus, so its node carries the standard SPI
properties, spi-max-frequency among them. With unevaluatedProperties:
false and no reference to spi-peripheral-props.yaml, dtbs_check rejects
those properties:

  can@1 (holt,hi3110): Unevaluated properties are not allowed
    ('spi-max-frequency' was unexpected)

Keep the properties and the example as the original text describes them,
including clocks as a required property.

v8:
 - Put back the $ref to spi/spi-peripheral-props.yaml. v7 dropped it as
   redundant, but the HI-3110 is an SPI peripheral and its node carries
   spi-max-frequency. With unevaluatedProperties: false and no reference,
   dt_binding_check reports:

     can@1 (holt,hi3110): Unevaluated properties are not allowed
       ('spi-max-frequency' was unexpected)

   A node carrying spi-max-frequency fails without the reference and passes
   with it, so the reference is required. Reported by sashiko.

   The schema is identical to the v6 that Rob reviewed, so his Reviewed-by
   is kept.

[PATCH v8 3/3] dt-bindings: net: can: fsl,mpc5xxx-mscan: Convert to DT schema

[Quchaosheng]

Convert the Freescale MPC5xxx MSCAN binding from free-form text to DT
schema.

The original text documents fsl,mpc5200-mscan and fsl,mpc5121-mscan in two
separate sections. Keep that split: fsl,mscan-clock-source takes "ip" or
"ref" on fsl,mpc5200-mscan, and "ip", "ref" or "sys" on fsl,mpc5121-mscan.

Add fsl,mpc5200b-mscan as a fallback of fsl,mpc5200-mscan. mpc5200b.dtsi
uses it.

Document clocks and clock-names, which the original text does not describe.
fsl,mpc5121-mscan requires the "ipg", "ips", "sys", "ref" and "mclk"
clocks in that order, as mpc5121.dtsi supplies them. MPC5200 does not use
DT clocks; it takes its frequency from the CDM block.

fsl,mscan-clock-divider divides the selected clock, so value 0 cannot be
used.

Keep the note that the MPC5121 Rev. 1 processor is not supported.

See https://patchwork.kernel.org/project/devicetree/patch/20260922102258.138753-3-quchaosheng000406@163.com

The base for the series is generally the latest rc1. A different dependency
should be noted in *this* patch.

If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure 'yamllint' is installed and dt-schema is up to
date:

pip3 install dtschema --upgrade

Please check and re-submit after running the above command yourself. Note
that DT_SCHEMA_FILES can be set to your schema file to speed up checking
your schema. However, it must be unset to test all examples with your schema.
