/*
* DO NOT change the device Ids. The naming is intentionally specific as both
* the PMIC and CODEC parts of this chip are instantiated separately as I2C
* devices (both have configurable I2C addresses, and are to all intents and
* purposes separate). As a result there are specific DA9055 ids for PMIC
* and CODEC, which must be different to operate together.
