From Nicolas Ferre:
An important revert on at91rm9200 platform related
to timers that prevented the platform to boot properly.
Then one pinctrl adjustments for SPI CS and a couple of
trivial typos.

* tag 'at91-fixes' of git://github.com/at91linux/linux-at91:
  ARM: at91: rm9200 fix time support
  ARM: at91: dts: request only spi cs-gpios used on sama5d3x cpu module
  ARM: at91/trivial: typo in GEM compatible string
  ARM: at91/trivial: fix model name for SAM9X25-EK
