Why did this go into v5.10-rc3? It's not a fix and now a fix is needed:

/builds/robherring/linux-dt-bindings/Documentation/devicetree/bindings/clock/imx5-clock.example.dt.yaml:
can@53fc8000: compatible: 'oneOf' conditional failed, one must be
fixed:
 ['fsl,imx53-flexcan', 'fsl,p1010-flexcan'] is too long
 Additional items are not allowed ('fsl,p1010-flexcan' was unexpected)
 'fsl,imx53-flexcan' is not one of ['fsl,imx7d-flexcan',
'fsl,imx6ul-flexcan', 'fsl,imx6sx-flexcan']
 'fsl,imx53-flexcan' is not one of ['fsl,ls1028ar1-flexcan']
 'fsl,imx6q-flexcan' was expected
 'fsl,lx2160ar1-flexcan' was expected
 From schema: /builds/robherring/linux-dt-bindings/Documentation/devicetree/bindings/net/can/fsl,flexcan.yaml
/builds/robherring/linux-dt-bindings/Documentation/devicetree/bindings/net/can/fsl,flexcan.example.dt.yaml:

Sorry, this was against the rules and not a good idea.

I've both issues and found two more. See the following thread for details:
