[PATCH 0/2] arm64: dts: fsl-lx2162a-som: add description for rtc

[Josua Mayer]

Add description for an on-som rtc that was missed in original submission
of device-tree.

Also update the clearfog reference carrier board aliases to include the
previously disabled i2c bus with this rtc.

[PATCH 2/2] arm64: dts: fsl-lx2162a-clearfog: add alias for i2c bus iic6

[Josua Mayer]

SoM dts has enabled  i2c bus IIC6 (dts i2c5), but defines no aliases.

LX2162A Clearfog dts has aliases for all i2c buses to ensure predictable
numbering for userspace. Add an additional alias for this extra bus.

My bot found new DTB warnings on the .dts files added or changed in this
series.

Some warnings may be from an existing SoC .dtsi. Or perhaps the warnings
are fixed by another series. Ultimately, it is up to the platform
maintainer whether these warnings are acceptable or not. No need to reply
unless the platform maintainer has comments.

If you already ran DT checks and didn't see these error(s), then
make sure dt-schema is up to date:

  pip3 install dtschema --upgrade


New warnings running 'make CHECK_DTBS=y freescale/fsl-lx2162a-clearfog.dtb' for 20240312-lx2162-rtc-v1-0-1f4cd431b1cf@solid-run.com:

arch/arm64/boot/dts/freescale/fsl-lx2162a-clearfog.dtb: i2c@2050000: Unevaluated properties are not allowed ('clock-names' was unexpected)
	from schema $id: http://devicetree.org/schemas/i2c/i2c-imx.yaml#
