RE: [PATCH v3 1/2] spi: cadence: add dt-bindings documentation for Cadence XSPI controller

quoted

Isn't stating that validation need against spi-controller.yaml as well as
this schema sufficient ? Can you please point an example how to make
controller binding a "subclass" of spi-controller.yaml binding ?

I just showed you. You need to add the below lines:

Oh, my bad. I already added that dependency in my local patches for next version,
I thought you are suggesting something else.

I think spi-controller.yaml uses wildcard for the name of a device node,
so anything in string@hexvalue: should work.

Sure, but mtd.yaml (which the SPI NOR binding depends on) requires it.

Ok, using "jedec,spi-nor" creates dependency on spi-nor schema, otherwise
I was not seeing any issue in " make dt_binding_check" with just "spi-nor".

This will be taken care in next version of patch set.
