HID: wacom: Intuos4 battery charging changes

2013-07-04T13:04:47+00:00

Intuos4 WL is separately reporting power supply and battery
charging status - now hid-wacom is using that information.
Previously hid-wacom was wrongly treating "battery charging" bit
as "power supply connected". Now it should report battery charging,
battery discharging, battery full and power supply status.

Intuos4 WL sends reports when is in use (obvious) and when unplugging
power supply. If means that if the device is being charged, but it's not
being used it will never report "battery full". The same problem happens
after the device has been connected, but it's not in use - the
battery/ac status will be incorrect. Currently there is no mechanism to
ask the device to send a report containing battery/ac status.

HID: Use module_hid_driver macro

2013-01-03T09:27:31+00:00

Use the new module_hid_driver macro in all HID drivers that have
a simple register/unregister init/exit.

This also converts the hid drivers that test for a failure of
hid_register_driver() and report the failure. Using module_hid_driver
in those drivers removes the failure message.

HID: wacom: Fix wacom_probe error handling

2012-09-19T11:40:56+00:00

OLEDs/LED are not critical for tablet functioning thus ignore OLED/LED
initialisation failures.

This patch does clean up all the sysfs attribute files in error paths.

HID: remove Paul Walmsley's copyright from places where it shouldn't be

2012-09-05T08:46:36+00:00

Paul Walmsley has implemented dynamic quirk handling back in 2007 through
commits:

2eb5dc30eb ("USB HID: encapsulate quirk handling into hid-quirks.c")
8222fbe67c ("USB HID: clarify static quirk handling as squirks")
8cef908235 ("USB HID: add support for dynamically-created quirks")
876b9276b9 ("USB HID: add 'quirks' module parameter")

and as such, his copyright rightly belongs to
drivers/hid/usbhid/hid-quirks.c file.

However when generic HID code has been converted to bus and individual
quirks separated out to individual drivers on the bus, the copyright has
been blindly transfered into all the tiny drivers, which actually don't
contain any of Pauls' copyrighted code.

Remove the copyright from those sub-drivers.

HID: wacom: OLEDs control over sysfs for Intuos4

2012-08-15T08:29:11+00:00

Thsi patch adds ability to control OLED micro displays on Wacom Intuos4
Wireless. The OLEDS are exposed as
/sys/class/hidraw/hidraw*/device/oled{No]_img
where No. is 0 to 7

Setting an image:

dd bs=256 if=img_file of=/sys/class/hidraw/hidraw{No}/device/oled0_img

The image has to contain 256 bytes (64x32px 1 bit). More detailed
description in Documentation/ABI/testing/sysfs-driver-wacom

HID: wacom: Use half of brightness for low state

2012-08-15T08:29:11+00:00

Intuos4 WL leds have 2 states: high and low. With no activity tablet
uses low state; using pen triggers high state. Both can be set
independently, but it would require setting another led device to
control them separately. This patch uses the brightness set through leds
subsytem as high and half of that value as low.

HID: wacom: Unify speed setting

2012-05-16T19:42:16+00:00

This patch unifies speed setting for both supported tablets. Functionality
of "wacom_poke" (used only by Graphire) is now in "wacom_set_features".
Reporting speed for both tablets can be changed by somethinkg like:

echo 1 > /sys/class/bluetooth/hci0/hci0:1/{device No}/speed

Accepted values:
0 - low speed,
1 - high speed.

The way of changing reporting speed is the same for Graphire and Intuos4 WL.

HID: wacom: Add speed setting for Intuos4 WL

2012-05-16T19:42:15+00:00

Add option to change reporting speed for Intuos4 WL. The option is only
internal to the module, but it will be extended to allow control over sysfs,
as it is already implemented for Graphire.

HID: wacom: Move Graphire raport header check.

2012-05-16T19:42:15+00:00

That check is valid only for Wacom Graphire, as the device raports always
start with 0x03. Intuos4 WL high-speed raports begin with 0x04, so
the check would be filtering out valid reports.
