[PATCH v2 0/4] spi: dw: Add basic runtime PM support

[Gareth Williams <gareth.williams.jx@xxxxxxxxxxx>]

The Renesas RZ/N1 SPI Controller is based on the Synopsys DW SSI. This
series enables power mode in the driver so the clock domain will enable
the bus clock, adds the compatible string and updates the associated bindings
documentation.

v2:
 - Note that pclk should be renamed when using a clock domain in the
   bindings documentation.
 - Set spi_controller.auto_runtime_pm instead of using
   pm_runtime_get_sync.
 - Added pm_runtime_disable calls to dw_spi_remove_host and the error
   condition of dw_spi_add_host.
