title: Renesas Expanded Serial Peripheral Interface (xSPI)

description: |
  Renesas xSPI allows a SPI flash connected to the SoC to be accessed via
  the memory-mapping or the manual command mode.

  The flash chip itself should be represented by a subnode of the XSPI node.
  The flash interface is selected based on the "compatible" property of this
  subnode:
  -  "jedec,spi-nor";
