2021-01-28dt-bindings: i2c: mv64xxx: Add H616 compatible stringAndre Przywara
Add the obvious compatible name to the existing I2C binding, and pair it with the existing A31 fallback compatible string, as the devices are compatible. On the way use enums to group all compatible devices together.

2021-01-17i2c: i2c-mux-gpio: Enable this driver in ACPI landEvan Green
Enable i2c-mux-gpio devices to be defined via ACPI. The idle-state property translates directly to a fwnode_property_*() call. The child reg property translates naturally into _ADR in ACPI. The i2c-parent binding is a relic from the days when the bindings dictated that all direct children of an I2C controller had to be I2C devices. These days that's no longer required. The i2c-mux can sit as a direct child of its parent controller, which is where it makes the most sense from a hardware description perspective. For the ACPI implementation we'll assume that's always how the i2c-mux-gpio is instantiated.
