This is an add-on series to the main SoC Sparx5 series
(Message-ID: <20200615133242.24911-1-lars.povlsen@xxxxxxxxxxxxx>
The series add support for the Sparx5 SoC SPI controller in the
spi-dw-mmio.c spi driver.
v3 changes:
- Added mux support for controlling SPI bus interface. This is new mux
driver, bindings and added to sparx5 base DT.
- Removed "microchip,spi-interface2" property in favour of
"mux-controls" property in SPI controller (sparx5 only).
- Changed dw_spi_sparx5_set_cs() to use the mux control instead of
directly acessing "mux" register. Associated code/defines moved to mux
driver.
- Changed dw_spi_sparx5_set_cs() to match other similar functions in
signature and avoid explicit CS toggling.
- Spun off duplicated NAND device DT chunks into separate DT file.
v2 changes:
- Moved all RX sample delay into spi-dw-core.c, using
the "snps,rx-sample-delay-ns" device property.
- Integrated Sparx5 support directly in spi-dw-mmio.c
- Changed SPI2 configuration to per-slave "microchip,spi-interface2"
property.
- Added bindings to existing snps,dw-apb-ssi.yaml file
- Dropped patches for polled mode and SPI memory operations.
