Merge branch 'wacom' into next

2014-08-07T06:31:48+00:00

Merge large update to Wacom driver, converting it from USB to a HID
driver and unifying wired and bluetooth support, from Benjamin
Tissoires.

Input: wacom - move the USB (now hid) Wacom driver in drivers/hid

2014-07-26T01:55:38+00:00

wacom.ko is now a full HID driver, we have to move it into the proper
subdirectory: drivers/hid.

Input: wacom - keep wacom_ids ordered

2014-07-26T01:53:56+00:00

No Functional changes, just some reordering.

Input: wacom - remove field pktlen declaration in the list of devices

2014-07-26T01:53:56+00:00

pktlen is now overwritten by the driver directly by reading the hid
report descriptor. There is no need to declare it statically.
We also move down the position of the field in the struct so that
we can keep the current declaration of Wacom devices.

Input: wacom - use hidinput_calc_abs_res instead of duplicating its code

2014-07-26T01:53:55+00:00

This may infer a small difference with the previous implementation
due to the DIV_ROUND_CLOSEST() in the hid implementation.

Input: wacom - use in-kernel HID parser

2014-07-26T01:53:55+00:00

HID already parses the report descriptor, so use it instead of implementing
our own.  The special case for Bamboo PT 3rd gen is also removed and
handled in the same way Intuos 5 is treated, by hardcoding it in the
driver.  Last, the unit_exponent stored into the hid field already is
signed, so there is no need to handle a two's complement anymore.

Input: wacom - register power device at the HID level

2014-07-26T01:53:53+00:00

Use the HID device as the parent for the power device when dealing with
a wireless receiver.
Removes one more usb dependency and does not break user space.

Input: wacom - remove usb dependency for siblings devices

2014-07-26T01:53:53+00:00

Wacom tablets can share different physical sensors on one physical device.
These are called siblings in the code. The current way of implementation
relies on the USB topology to be able to share data amongs those sensors.

We can replace the code to match a HID subsystem, without involving the USB
topology:
- the first probed sensor does not find any siblings in the list
  wacom_udev_list, so it creates its own wacom_hdev_data with its own
  struct hid_device
- the other sensor checks the current list of siblings in wacom_hdev_data,
  and if there is a match, it associates itself to the matched device.

To be sure that we are not associating different sensors from different
physical devices, we also check for the phys path of the hid device which
contains the USB topology.
