[PATCH v2 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@60000000/tve@63ff0000: failed to match any schema with compatible: ['fsl,imx53-tve']

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 2 potential issue(s) to consider:
- [Medium] The commit message incorrectly cites a CHECK_DTBS warning for a TV encoder ('fsl,imx53-tve') instead of the ZigBee transceiver ('fsl,mc1323') that the patch actually adds.
- [Low] A complex ZigBee radio transceiver is incorrectly classified as a trivial device, masking an incomplete device tree node.

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 bindings list to resolve dtbs_check 
warnings on the i.MX53 SMD board.

[Severity: Medium]
Is the CHECK_DTBS warning cited here correct for this patch?

The warning mentions a TV encoder ('fsl,imx53-tve') at a different node,
but this patch adds the ZigBee transceiver ('fsl,mc1323'). 

It looks like the wrong error log might have been pasted into the commit
message.

[Severity: Low]
Should a complex ZigBee radio transceiver be classified as a trivial device?

The trivial-devices.yaml schema is intended for simple devices requiring
only compatible, reg, and optionally interrupts properties. As an IEEE
802.15.4 MAC/PHY transceiver, wouldn't the MC1323 inherently require other
hardware resources like clocks or regulators?

Adding it to the trivial list seems to bypass proper DT validation and
could mask an incomplete device tree node.

Sorry, paste wrong error log here, should be

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']
