Microsoft published the protocol specification of HID over i2c:

This patch introduces an implementation of this protocol.

This implementation does not includes the ACPI part of the specification.
This will come when ACPI 5.0 devices enumeration will be available.

Once the ACPI part is done, OEM will not have to declare HID over I2C
devices in their platform specific driver.

Hi Guys,

here is the v3 of the HID over I2C driver.

Changes in v3:
* fix i2c_hid_alloc_buffers when allocation failed
* fix error messages to be more "human"
* fix i2c_hid_set_report as it didn't followed the protocol
* remove i2c_hid_write_out_report (hid-core doesn't present the callback that
could use this feature of the protocol)
* reject HID_OUTPUT_REPORT in i2c_hid_get_raw_report
* fix output report id in i2c_hid_output_raw_report and reject HID_INPUT_REPORT

Benjamin,

I am now queuing this in for-3.8/i2c-hid branch, so please send any 
potential followup patches on top of that.

Thanks a lot for all your work on this so far.
