From: Nina Wu <Nina-CM.Wu@mediatek.com>
For new ICs, there are multiple devapc HWs for different subsys. We add a field 'vio-idx-num' in DT to indicate the number of devices controlled by each devapc. To be backward compatible with old ICs which have only one devapc HW, this field is not required. The 'vio-idx-num' info will be set in compatible data instead.
