[PATCH 0/2] dt-bindings: net: can: cc770: convert the binding, fix the driver comment

[Quchaosheng]

From: Chaosheng Qu <quchaosheng000406@163.com>

Krzysztof dropped the whole thread from the DT patchwork on 09-15: four
patches went out in one thread and confused the tooling.  This is the
same work, sent as one two-patch series with a cover letter, which is
what Marc asked for on the CAN side.

  [1/2] converts cc770.txt to DT schema.
  [2/2] updates the file name in the comment at the top of the platform
        driver, now that the text binding is gone.

Both carry Assisted-by: LLM, which the first posting was missing, and
neither has been reviewed by anyone yet -- the previous thread was
dropped before that could happen.

[PATCH 1/2] dt-bindings: net: can: bosch,cc770: Convert to DT schema

[Quchaosheng]

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.

-Memory mapped Bosch CC770 and Intel AN82527 CAN controller
-
-Note: The CC770 is a CAN controller from Bosch, which is 100%
-compatible with the old AN82527 from Intel, but with "bugs" being fixed.
-
-Required properties:
-
-- compatible : should be "bosch,cc770" for the CC770 and "intc,82527"
-	for the AN82527.
-
-- reg : should specify the chip select, address offset and size required
-	to map the registers of the controller. The size is usually 0x80.
-
-- interrupts : property with a value describing the interrupt source
-	(number and sensitivity) required for the controller.
-
-Optional properties:
-
-- bosch,external-clock-frequency : frequency of the external oscillator
-	clock in Hz. Note that the internal clock frequency used by the
-	controller is half of that value. If not specified, a default
-	value of 16000000 (16 MHz) is used.
-
-- bosch,clock-out-frequency : slock frequency in Hz on the CLKOUT pin.
-	If not specified or if the specified value is 0, the CLKOUT pin
-	will be disabled.
-
-- bosch,slew-rate : slew rate of the CLKOUT signal. If not specified,
-	a reasonable value will be calculated.
-
-- bosch,disconnect-rx0-input : see data sheet.
-
-- bosch,disconnect-rx1-input : see data sheet.
-
-- bosch,disconnect-tx1-output : see data sheet.
-
-- bosch,polarity-dominant : see data sheet.
-
-- bosch,divide-memory-clock : see data sheet.
-
-- bosch,iso-low-speed-mux : see data sheet.
-
-For further information, please have a look to the CC770 or AN82527.
-
-Examples:
-
-can@3,100 {
-	compatible = "bosch,cc770";
-	reg = <3 0x100 0x80>;
-	interrupts = <2 0>;
-	interrupt-parent = <&mpic>;
-	bosch,external-clock-frequency = <16000000>;
-};
