Merge tag 'at91-fixes' of git://github.com/at91linux/linux-at91 into fixes

From  Nicolas Ferre <nicolas.ferre@atmel.com>:

A mix of typos and critical fixes.
The most important ones are a duplicated definition of a Kconfig
variable and the handling of external interrupts for non-DT case.
The new at91sam9g10 was suffering a recognition issue due to an ID
mis-interpreted: this was leading to a kernel panic.

* tag 'at91-fixes' of git://github.com/at91linux/linux-at91: (257 commits)
  ARM: at91: drop duplicated config SOC_AT91SAM9 entry
  ARM: at91/i2c: change id to let i2c-at91 work
  ARM: at91/i2c: change id to let i2c-gpio work
  ARM: at91/dts: at91sam9g20ek_common: Fix typos in buttons labels.
  ARM: at91: fix external interrupt specification in board code
  ARM: at91: fix external interrupts in non-DT case
  ARM: at91: at91sam9g10: fix SOC type detection
  ARM: at91/tc: fix typo in the DT document
