HID: hid-sensor-hub: Processing for duplicate physical ids
In HID sensor hub, HID physical ids are used to represent different sensors. For example physical id of 0x73 in usage page = 0x20, represents an accelerometer. The HID sensor hub driver uses this physical ids to create platform devices using MFD. There is 1:1 correspondence between an phy id and a client driver. But in some cases these physical ids are reused. There is a phy id 0xe1, which specifies a custom sensor, which can exist multiple times to represent various custom sensors. In this case there can be multiple instances of client MFD drivers, processing specific custom sensor. In this case when client driver looks for report id or a field index, it should still get the report id specific to its own type. This is also true for reports, they should be directed towards correct instance. This change introduce a way to parse and tie physical devices to their correct instance. Summary of changes: - To get physical ids, use collections. If a co...
