Geert Uytterhoeven 41a7458147 Input: wacom - fix compiler warning if !CONFIG_PM
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.

Benjamin Tissoires c704b4ef1a Input: wacom - update the ABI doc according to latest changes
Now the devices show up under hid no matter the connection (for USB
and Bluetooth, not serial nor i2c).

The USB devices can now be easily found under
/sys/bus/hid/devices/<bus>:<vid>:<pid>.<n>

The Bluetooth devices could also be found under this path since their
inclusion (April 2010), so this patch fixes the non-precise "hidraw*" path
for them.

The ABI has been unified while setting the LEDs and OLEDs. So Bluetooth
devices lost their own LED selector but use the USB sysfs attribute.
For OLEDs, Bluetooth devices handle only 1-bit images instead of 4 for USB.
The documentation has been updated to match this.

Benjamin Tissoires 849e2f0678 Input: wacom - check for bluetooth protocol while setting OLEDs
Bluetooth Intuos 4 use 1-bit definition while the USB ones use a 4-bits

Nick Dyer 9d469d033d Input: atmel_mxt_ts - use deep sleep mode when stopped
By writing zero to both the active and idle cycle times the maXTouch device
is put into a deep sleep mode when it consumes minimal power. It is
unnecessary to change the configuration of any other objects (for example
to disable T9 touchscreen).

It is counterproductive to reset the chip on resume, it will result in a
long delay. However it is necessary to issue a calibrate command after the
chip has spent any time in deep sleep.

This patch also deals with the situation where the power configuration is
zero on probe, which would mean that the device never wakes up to execute
commands.

Benjamin Tissoires c757cbafd6 Input: wacom - put a flag when the led are initialized
This solves a bug with the wireless receiver:
- at plug, the wireless receiver does not know which Wacom device it is
  connected to, so it does not actually creates all the LEDs
- when the tablet connects, wacom->wacom_wac.features.type is set to the
  proper device so that wacom_wac can understand the packets
- when the receiver is unplugged, it detects that a LED should have been
  created (based on wacom->wacom_wac.features.type) and tries to remove
  it: crash when removing the sysfs group.

Side effect, we can now safely call several times wacom_destroy_leds().

Benjamin Tissoires 80befa9381 Input: wacom - remove field pktlen declaration in the list of devices
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.
