[PATCH v3 1/1] dt-bindings: trivial-devices: add fsl,mc1323

[Frank.Li]

From: Frank Li <Frank.Li@nxp.com>

Add freescale 2.4 GHz IEEE® 802.15.4/ZigBee mc1323 to fix the below
CHECK_DTBS warnings.
  arch/arm/boot/dts/nxp/imx/imx53-smd.dtb: /soc/bus@50000000/spba-bus@50000000/spi@50010000/mc1323@0: failed to match any schema with compatible: ['fsl,mc1323']

Since the i.MX53 platform is more than 20 years old, it is difficult to
find detailed information about how the MC1323 was used on the i.MX53 SMD
board, as the functionality depended on firmware.

Thank you for your contribution! Sashiko AI review found 1 potential issue(s) to consider:
- [Low] The complex 802.15.4/ZigBee transceiver (Freescale MC1323) is being incorrectly added to trivial-devices.yaml.

dt-bindings: trivial-devices: add fsl,mc1323

This commit adds the Freescale MC1323 2.4 GHz IEEE 802.15.4/ZigBee
transceiver to the trivial-devices binding. This change is intended to
resolve dtbs_check warnings on the legacy i.MX53 SMD platform where the
device was used.

[Severity: Low]
Is it appropriate to add the Freescale MC1323 to trivial-devices.yaml?

The trivial-devices schema is strictly intended for simple I2C/SPI components
that genuinely require no hardware properties other than a compatible string,
reg, and optionally a single interrupt. 

Since the MC1323 is a complex IEEE 802.15.4 MAC/PHY SoC, does using
trivial-devices.yaml as a workaround for sparse legacy device tree nodes
create a regression in binding purity? 

Would it be better to create a dedicated minimal schema in
Documentation/devicetree/bindings/net/ieee802154/ instead, even if it
initially only lists the minimal properties needed to validate the legacy
i.MX53 SMD device tree?

Applied, thanks!
