Input: wacom - fix compiler warning if !CONFIG_PM

2014-08-12T16:59:29+00:00

If CONFIG_PM is not set:

drivers/hid/wacom_sys.c:1436: warning: ‘wacom_reset_resume’ defined but
not used

Protect the unused functions by #ifdef CONFIG_PM to fix this.

Input: wacom - only register once the MODULE_* macros

2014-08-06T22:14:55+00:00

Putting the various MODULE_* makes them appear several times in modinfo
because wacom.h is used both in wacom_sys.c and wacom_wac.h.
Having the macros near the module declaration makes them appear only once.

Add also MODULE_VERSION(DRIVER_VERSION) to export the current version
number.

Input: wacom - remove passing id for wacom_set_report

2014-08-06T22:14:53+00:00

Every call of wacom_set_report was passing "id" as a separate parameter
and buffer also passed the same information. We can use first u8 of the
buffer instead of "id"

Input: wacom - check for bluetooth protocol while setting OLEDs

2014-08-06T22:14:52+00:00

Bluetooth Intuos 4 use 1-bit definition while the USB ones use a 4-bits
definition. This changes the size of the raw image we receive, and thus
the kernel will only accept 1-bit images for Bluetooth and 4-bits for
USB.

Input: wacom - handle Intuos 4 BT in wacom.ko

2014-08-06T22:14:34+00:00

A good point of this change is that now, the Intuos4 bluetooth can handle
the different tools (artpen, airbrush, mice), and we get a common interface
between USB and BT for accessing the LEDs/OLEDs.

Input: wacom - prepare the driver to include BT devices

2014-08-06T21:18:10+00:00

Now that wacom is a hid driver, there is no point in having a separate
driver for bluetooth devices. This patch prepares the common paths of
Bluetooth devices in the common wacom driver. It also adds the sysfs file
"speed" used by Bluetooth devices.

Input: wacom - register an ac power supply for wireless devices

2014-07-26T01:55:54+00:00

This is used by HID Bluetooth devices but also add some more information
to the USB Wireless Receiver.
We are just porting the bits from hid-wacom.c to the common driver here.

Input: wacom - use a uniq name for the battery device

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

The current implementation uses "wacom_battery" as a generic name for
batteries. This prevents us to have two Wacom devices with a battery
attached as the power system will complain about the name which is already
registered.

Use an incremental name for each battery attached.

Input: wacom - enhance Wireless Receiver battery reporting

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

- Reports the current status of the battery (discharging, charging, full).
- Also notify the upower daemon when there is a change in the battery
  value.
- keep the battery value as a percentage, not the raw value
- add WACOM_QUIRK_BATTERY to easily add a battery to a device (required
  for Bluetooth devices)
