[PATCH v5 5/6] spi: at91-usart: add driver for at91-usart as spi

This is the driver for at91-usart in spi mode. The USART IP can be configured to work in many modes and one of them is SPI. The driver was tested on sama5d3-xplained and sama5d4-xplained boards with enc28j60 ethernet controller as slave. Signed-off-by: Radu Pirea --- drivers/spi/Kconfig

[PATCH v5 3/6] mfd: at91-usart: added mfd driver for usart

This mfd driver is just a wrapper over atmel_serial driver and spi-at91-usart driver. Selection of one of the drivers is based on a property from device tree. If the property is not specified, the default driver is atmel_serial. Signed-off-by: Radu Pirea Acked-by: Rob Herring --- drivers/mfd
