Subject: [PATCH 00/10] spi: Adding support for Microchip Sparx5 SoC

This is an add-on series to the main SoC Sparx5 series
(Message-ID: <20200513125532.24585-1-lars.povlsen@...rochip.com>).

The series add support for Sparx5 on top of the existing
ocelot/jaguar2 spi driver.

It spins off the existing support for the MSCC platforms into a
separate driver, as adding new platforms from the MSCC/Microchip
product lines will further complicate (clutter) the original driver.

New YAML dt-bindings are provided for the resulting driver.

It is expected that the DT patches are to be taken directly by the arm-soc
maintainers.

Lars Povlsen (10):
  spi: dw: Add support for polled operation via no IRQ specified in DT
  spi: dw: Add support for RX sample delay register
  spi: dw: Add support for client driver memory operations
  dt-bindings: spi: Add bindings for spi-dw-mchp
  spi: spi-dw-mmio: Spin off MSCC platforms into spi-dw-mchp
  dt-bindings: spi: spi-dw-mchp: Add Sparx5 support
  spi: spi-dw-mchp: Add Sparx5 support
  arm64: dts: sparx5: Add SPI controller
  arm64: dts: sparx5: Add spi-nor support
  arm64: dts: sparx5: Add spi-nand devices
