Subject: [PATCH v2 0/3] Add bindings for slave-specific SPI controller properties

Hi,

This series adds bindings for slave-specific SPI controller properties.
See patch 1 for more info on the motivations behind this.

This is the best approach that I came up with with my limited knowledge
of JSON schema. It has some limitations that are mentioned in patch 1. I
don't know of any better ways to model this. Suggestions are welcome!

Changes in v2:
- Move other subnode properties listed in spi-controller.yaml to
  spi-slave-props.yaml
- Move the Cadence controller-specific properties out of
  spi-slave-props.yaml. They will be added in a separate file.
- Add a reference to spi-slave-props.yaml in spi-controller.yaml.
- Update description.

  spi: dt-bindings: add schema listing slave-specific properties
  spi: dt-bindings: cdns,qspi-nor: Move slave-specific properties out
  dt-bindings: mtd: spi-nor: Add a reference to spi-slave-props.yaml
