Subject: [PATCH v2 0/5] Add i2c bus recovery support for Atmel SoCs

Some Atmel SoCs actually doesn't support the clear command for recovery.
This patch serie merge the two support for both i2c bus recovery
mechanism (clear command and gpio/pinctrl).

Codrin Ciubotariu (1):
  i2c: at91: Send bus clear command if SCL or SDA is down

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
