[PATCH 0/3] ARM: at91/DT: enable SPI for more SoCs

[Nicolas Ferre]

This little series is for enabling the support of SPI on at91sam9n12 and
sama5d3 families.

Nicolas Ferre (3):
  ARM: at91/DT: fix SPI compatibility string
  ARM: at91/DT: sama5d3: add SPI DMA client infos
  ARM: at91/DT: at91sam9n12: add SPI DMA client infos

[PATCH 1/3] ARM: at91/DT: fix SPI compatibility string

[Nicolas Ferre]

In previous version of SPI driver we where using different compatibility stings
for finding SPI features. We are now using the IP revision information.
So we stay with the unique compatibility string for this driver:
"atmel,at91rm9200-spi".
