The integration of the Designware SPI controller on Microsemi SoCs requires an extra register set to be able to give the IP control of the SPI interface. Cc: Rob Herring <robh+dt@xxxxxxxxxx> Signed-off-by: Alexandre Belloni <alexandre.belloni@xxxxxxxxxxx> --- Changes in v4: - changed subject to be prefixed by spi: dw: - documented possible <soc> values. jaguar2 support will be added later to the driver.
