This combo has support for multiple devices but, for a start, only the following have been implemented: - Regulators (two instances, one in MT6331, one in MT6332) - RTC (MT6331) - Keys (MT6331) - Interrupts (MT6331 also dispatches MT6332's interrupts) There's more to be implemented, especially for MT6332, which will come at a later stage.
