[PATCH] ARM: dts: imx7s-warp: Pass OV2680 link-frequencies

[PATCH] ARM: dts: imx7s-warp: Pass OV2680 link-frequencies

[Fabio Estevam]

From: Fabio Estevam <festevam@denx.de>

Since commit 63b0cd30b78e ("media: ov2680: Add bus-cfg / endpoint
property verification") the ov2680 no longer probes on a imx7s-warp7:

ov2680 1-0036: error -EINVAL: supported link freq 330000000 not found
ov2680 1-0036: probe with driver ov2680 failed with error -22

Fix it by passing the required 'link-frequencies' property as
recommended by:

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 nxp/imx/imx7s-warp.dtb' for 20240328151954.2517368-1-festevam@gmail.com:

So it sounds like that the bindings doc needs an update to include
'link-frequencies'?
