When iicbus is attached as child of Designware I2C controller it scans all ACPI nodes for "I2C Serial Bus Connection Resource Descriptor" described in section 19.6.57 of ACPI specs. If such a descriptor is found, I2C child is added to iicbus, it's I2C address, IRQ resource and ACPI handle are added to ivars. Existing ACPI bus-hosted child is deleted afterwards. The driver also installs so called "I2C address space handler" which is disabled by default as nontested. Set hw.iicbus.enable_acpi_space_handler loader tunable to 1 to enable it.
