This patch series introduce the kernel i2c-gpio bus recovery mechanism
for the Microchip SoCs. Updated the corresponding dts to add i2c
gpio pinctrl. The bus recovery is configured for the sama5d3/4 xplained
boards in dts.

Kamel Bouhara (4):
  dt-bindings: i2c: at91: document optional bus recovery properties
  i2c: at91: implement i2c bus recovery
  ARM: at91/dt: sama5d3: add i2c gpio pinctrl
  ARM: at91/dt: sama5d4: add i2c gpio pinctrl

Now we have 2 drivers with the same binding and code for using GPIO for 
bus recovery. Perhaps all this should be common.
