| * HID: hid-sensor-hub: fix report sizeSrinivas Pandruvada2013-10-301-5/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Most of the hid sensor field size is reported in report_size field in the report descriptor. For rotation fusion sensor the quaternion data is 16 byte field, the report size was set to 4 and report count field is set to 4. So the total size is 16 bytes. But the current driver has a bug and not taking account for report count field. This causes user space to see only 4 bytes of data sent via IIO interface. The number of bytes in a field needs to take account of report_count field. Need to multiply report_size and report_count to get total number of bytes.

* HID: use hid_hw_wait() instead of direct call to usbhidBenjamin Tissoires2013-02-251-3/+2Star
| | | | | | | | | | | | | | | | | | | | | | | | This removes most of the dependencies between hid drivers and usbhid. The patch was constructed by replacing all occurences of usbhid_wait_io() by its hid_hw_wait() counterpart. Then, drivers not requiring USB_HID anymore have their USB_HID dependency cleaned in the Kconfig file. As of today, few drivers are still requiring an explicit USB layer dependency: * ntrig (a patch is on its way) * multitouch (one patch following and another on its way) * lenovo tpkbd * roccat * sony The last three are two deeply using direct calls to the usb subsystem to be able to be cleaned right now.

* HID: use hid_hw_request() instead of direct call to usbhidBenjamin Tissoires2013-02-251-4/+3Star
| | | | | | | | | | | | | | | | | | | This allows the hid drivers to be independent from the transport layer. The patch was constructed by replacing all occurences of usbhid_submit_report() by its hid_hw_request() counterpart. Then, drivers not requiring USB_HID anymore have their USB_HID dependency cleaned in the Kconfig file. Finally, few drivers still depends on USB_HID. Many of them are requiring the io wait callback. They are found in the next patch.

* HID: sensors: introduce sensor frameworksrinivas pandruvada2012-09-061-0/+695
Adding processing for HID Sensor usage table as defined by HID 1.12, Request #: HUTRR39, dated 05 May, 2011. This driver uses HID driver framework to register, send and receive events. This uses MFD framework, so that actual processing for a specific usage id can be done in a different driver. For example an accelerometer driver can be a separate driver and use the interface provided by this driver to register for events.
