Subject: [PATCH v2 0/4] enable flexspi support on imx8mp


This series enables support for the SPI NOR on the
imx8mp based phyboard-pollux-rdk board.

Patches new in v2:
"spi: fspi: enable fspi driver for on imx8mp"
which adds own compatible entry for imx8mp

and seperate in own patch the documentation entry in
patch "dt-bindings: spi: add compatible entry for imx8mp in FlexSPI controller"
as checkpatch says:

warning: DT binding docs and includes should be a separate patch. See: Documentation/devicetree/bindings/submitting-patches.rst


Changes in v2:
- work in comments from Marco
  add own compatible entry for imx8mp
- work in comments from Marco
  - add own compatible entry "nxp,imx8mp-fspi"
  - reworked order of properties as Marco mentioned
- work in comments from Marco and Teresa
  - rename node into "'som_flash: flash@0 { }"
  - compatible is now first entry
  - removed #size-cells and #address-cells
    as no child node. If bootloader adds them bootloader
    can add them too.

Heiko Schocher (4):
  spi: fspi: enable fspi driver for on imx8mp
  dt-bindings: spi: add compatible entry for imx8mp in FlexSPI
    controller
  arm64: dts: imx8mp: add flexspi node
  arm64: imx8mp: imx8mp-phycore-som enable spi nor
