i2c: i2c-gpio: Support the named GPIO binding 2021-08-22T09:03:55+00:00 Samuel Holland samuel@sholland.org 2021-08-22T00:25:43+00:00 7282b4352eba74e134c7ebba945338e418ec7faf To avoid confusion about the order of the GPIOs, the i2c-gpio binding was updated to use a separate property for each GPIO instead of an array. However, the driver only supports the old binding. Add support for the new binding as well, so the driver continues to work as device trees are updated.
