[Marc Kleine-Budde]

Hello netdev-team,

this is a pull request of 7 patches for net-next/main.

This series by Quchaosheng, converts the textual device tree bindings
description of the bosch,cc770, ifi,canfd, holt,hi311x,
fsl,mpc5xxx-mscan and the aeroflexgaisler,grcan devices from pure text
to yaml format.

regards,
Marc

[PATCH net-next 1/7] dt-bindings: net: can: ifi,canfd-1.0: Convert to DT schema

[Marc Kleine-Budde]

From: Quchaosheng <quchaosheng000406@163.com>

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 net-next 2/7] dt-bindings: net: can: bosch,cc770: Convert to DT schema

[Marc Kleine-Budde]

From: Chaosheng Qu <quchaosheng000406@163.com>

Convert the Bosch CC770 and Intel AN82527 controller binding from
free-form text to DT schema, and reference the common can-controller.yaml
schema.

The driver reads one more property than the old text documented:
"bosch,no-comperator-bypass", which is checked at cc770_platform.c:94.
It is documented here so that it can be used. Its spelling is kept as
the driver spells it.

The interrupt is obtained with platform_get_irq(), so interrupts is
required. The register window is described with the chip select, the
address offset and the size, as the original text and the existing
device trees on the local bus use three cells. The size is usually 0x80.

unevaluatedProperties is used rather than additionalProperties so that
properties provided by can-controller.yaml, such as termination-gpios,
remain usable.

[PATCH net-next 3/7] dt-bindings: net: can: holt,hi311x: Convert to DT schema

[Marc Kleine-Budde]

From: Quchaosheng <quchaosheng000406@163.com>

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.

[PATCH net-next 5/7] dt-bindings: net: can: fsl,mpc5xxx-mscan: Convert to DT schema

[Marc Kleine-Budde]

From: Quchaosheng <quchaosheng000406@163.com>

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.

[PATCH net-next 6/7] dt-bindings: net: can: convert grcan to DT schema

[Marc Kleine-Budde]

From: Quchaosheng <quchaosheng000406@163.com>

grcan.txt is the only CAN controller binding whose device does not have a
compatible string.  There are no device tree source files for LEON SPARC,
and the nodes are built by the PROM from the AMBA plug&play information,
which carries a core name and a register window but no compatible.  The
driver matches on the node name instead.

It is the last of the five CAN controller bindings that were still written
as free-form text; the other four are posted separately.

A binding without a compatible string is not selected by dtbs_check,
because nodes are matched through their compatible values.  The schema
therefore needs an explicit select on the node name.  This is the same
mechanism ethernet-phy.yaml uses for optional-compatible nodes, and
without it the schema would never be applied to anything.

Two further details are worth pointing out, because the text binding got
them wrong or left them implicit:

  - "systemid" is not a property of the controller node.  The driver and
    arch/sparc/kernel/leon_kernel.c both read it from the "/ambapp0" node,
    so it is described in the description rather than in properties.  The
    binding is stricter than the text file here, and dtbs_check now
    rejects a controller node that carries it.

  - The node name format is "<core name>@<irq>,<address>", as built by
    ambapp_path_component() in arch/sparc/kernel/prom_32.c from the "name"
    and "reg" properties of the AMBA plug&play core.  The select pattern
    and the example follow that format.

The "name" property of the text binding is not described: dtc enforces
that it equals the base node name and then deletes it from the output, so
it never reaches a compiled devicetree.

This binding does not reference can-controller.yaml, unlike the other CAN
controller schemas.  That common schema constrains the node name to
"^can(@.*)?$", which these nodes cannot satisfy -- they are named after
the AMBA plug&play core.  Referencing it makes every valid node fail.

No functional change.  The driver comment is updated by a separate patch.

IMHO this is outdated information. Since d4563201f33a ("Documentation:
simplify and clarify DCO contribution example language")
submitting-patches.rst requires a "known identity" not a real name.

Bad bot! The commit message says the meaning of the 3rd value of the
interrupts property is unchanged, it's the standard meaning as defined
in "dt-bindings/interrupt-controller/irq.h". The example lists only one
example, not all possibilities.
