Subject: [PATCH v2 1/2] dt-bindings: i2c: mv64xxx: add reset-gpios property

Add reset-gpios and reset-delay-us properties to the marvell,mv64xxx-i2c
binding. These can be used to describe hardware where a common reset
GPIO is connected to all downstream devices on and I2C bus. This reset
will be released before the downstream devices on the bus are probed.

Signed-off-by: Chris Packham <>

    Changes in v2:
    - Update commit message
    - Add reset-delay-us property
