Ping! And now Linus' tree is broken. If you can't be bothered to fix
this, perhaps it should be reverted.

This breaks linux-next and you didn't test with 'make dt_binding_check':

/builds/robherring/linux-dt-bindings/Documentation/devicetree/bindings/spi/spi-fsl-lpspi.yaml:
properties:fsl,spi-only-use-cs1-sel: {'description': 'spi common code
does not support use of CS signals discontinuously. i.MX8DXL-EVK board
only uses CS1 without using CS0. Therefore, add this property to
re-config the chipselect value in the LPSPI driver.'} is not valid
under any of the given schemas (Possible causes of the failure):
 
/builds/robherring/linux-dt-bindings/Documentation/devicetree/bindings/spi/spi-fsl-lpspi.yaml:
properties:fsl,spi-only-use-cs1-sel: 'not' is a required property

The problem is you need a type definition for a vendor specific
property. In this case 'type: boolean'.

[PATCH V2 4/4] dt-bindings: lpspi: New property in document DT bindings for LPSPI

2020-07-26 Thread Clark Wang
Add "fsl,spi-only-use-cs1-sel" to fit i.MX8DXL-EVK.
Spi common code does not support use of CS signals discontinuously.
It only uses CS1 without using CS0. So, add this property to re-config
chipselect value.
