ARM: dts: at91: Configure I2C SCL gpio as open drain
Browse files Browse the repository at this point in the history 
The SCL gpio pin used by I2C bus for recovery needs to be configured as
open drain.

Fixes: 455fec9 ("ARM: dts: at91: sama5d2: add i2c gpio pinctrl")
Fixes: a4bd8da ("ARM: dts: at91: sama5d3: add i2c gpio pinctrl")
Fixes: 8fb82f0 ("ARM: dts: at91: sama5d4: add i2c gpio pinctrl")
