2013-08-19hid: roccat-kone: convert class code to use bin_attrs in groupsGreg Kroah-Hartman
Now that attribute groups support binary attributes, use them instead of the dev_bin_attrs field in struct class, as that is going away soon. Cc: Jiri Kosina <jkosina@suse.cz> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2013-08-19HID: roccat: convert class code to use dev_groupsGreg Kroah-Hartman
The dev_attrs field of struct class is going away soon, dev_groups should be used instead. This converts the roccat class code to use the correct field. Cc: Jiri Kosina <jkosina@suse.cz> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2013-07-23HID: replace strict_strtoul() with kstrtoul()Jingoo Han
The usage of strict_strtoul() is not preferred, because strict_strtoul() is obsolete. Thus, kstrtoul() should be used. Signed-off-by: Jingoo Han <jg1.han@samsung.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>

2011-09-07HID: roccat: cleaned up code for Kone and fixed wrong initialization valueStefan Achatz

2011-06-13HID: roccat: fix NULL pointer dereference, add range checksStefan Achatz
On rare occassions raw events can be triggered before drvdata gets set up which leads to NULL pointer dereferences. This was only observed with pyra on 2.6.39, but is fixed for all devices now to play it save. kovaplus returned wrong actual values when profile change was initiated from host. Added range checks for setting actual profile on all devices. Signed-off-by: Stefan Achatz <erazor_de@users.sourceforge.net> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
2011-06-13HID: roccat: correction and cleanup of HID feature reportsStefan Achatz
Removed analog feature report enums and modified code in roccat_common to reflect this. Non standard conform Kone got its own copy of the old code. That helps extracting more generalizations for newer devices. Signed-off-by: Stefan Achatz <erazor_de@users.sourceforge.net> Signed-off-by: Jiri Kosina <jkosina@suse.cz>

2011-02-03HID: roccat: Fix NULL pointer dereference when unloading moduleStefan Achatz
Class was destroyed before starting the unregistering driver chain. Disconnecting a device from roccat chardev in this process then raised a NULL pointer dereference. Fixed this by destroying class after unregistering driver. Signed-off-by: Stefan Achatz <erazor_de@users.sourceforge.net> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
2011-02-03HID: roccat: Add ioctl command to retreive report size from chardevStefan Achatz
Roccat chardev was reworked to support only a defined report size per device and this can be retreived by an ioctl now to enable future changes in report definitions. Header was moved/renamed from drivers/hid to include/linux for accessibility. Signed-off-by: Stefan Achatz <erazor_de@users.sourceforge.net> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
2011-02-03HID: roccat: Introduce module hid-roccat-commonStefan Achatz
Module hid-roccat-common contains functions used by roccat device driver modules to reduce code duplication. At the moment it contains just two wrapper methods for usb_control_msg that ensure that the buffer used for transfer is dma capable which wasn't the case before. The kconfig option is not visible to the user but will be selected by the device specific drivers.

2011-01-08HID: roccat: use class for char device for sysfs attribute creationStefan Achatz

2010-06-21HID: roccat: remove obsolete kone_abi_version sysfs attributeStefan Achatz
The newest version of the accompanying userland tools cuts backward compatibility and uses libudev to find its devices superseding the quirky kone_abi_version sysfs attribute.

2010-05-25HID: roccat: propagate special events of roccat hardware to userspaceStefan Achatz
Module roccat is a char device used to report special events of roccat hardware to userland. These events include requests for on-screen-display of profile or dpi settings or requests for execution of macro sequences that are not stored in device. The information in these events depends on hid device implementation and contains data that is not available in a single hid event or else hidraw could have been used. It is inspired by hidraw, but uses only one circular buffer for all readers. The device is as generic as possible so that the functionality is usable by all (kone and upcomming) roccat device drivers.

2010-03-22HID: add driver for Roccat Kone gaming mouseStefan Achatz
This Patch adds support for Kone gaming mouse from Roccat. It provides access to profiles, settings, firmware, weight, actual settings etc. through sysfs attributes. Event handling of this mouse differs from standard hid behaviour in that tilt button press is reported in each move event which results in strange behaviour if not handled by the driver. This is a heavily reworked version of the previously introduced driver. The changes include most of the previously raised concerns, memory leak and other fixes, code cleanups, adoption of additional achieved knowlege about the hardware and is (IMHO) a much better version than before even when I exchanged reduced USB-IO with a bigger memory consumption. I refused to implement one mentioned point: Removing the 'just-because-we-can' attributes. Motivation: Reading the clipped in weight: I'm no gamer and can't determine the usefulness of this feature but if the manufacturer implements such a feature it might make sense to someone and I would unwillingly limit the functionality besides its such a small feature. Reading the actual profile and dpi settings: Here I can testify that one can get lost of the actual settings when switching back and forth. The manufacturers windows driver has the ability for on-screen-display of the values and there is a mouse in the market that has an lcd on the underside of it to show these values. So I think this feature makes sense not only for me and shouldn't be removed. Signed-off-by: Stefan Achatz <erazor_de@users.sourceforge.net> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
