HID: hid-lg: Allow for custom device-specific properties to be stored in priv drvdata This patch adds support for custom device-specific properties which can now be stored as private driver data and read/saved using hid_get/set_drvdata().

HID: add driver for the Logitech Flight System G940 Implements a new USB-HID for Force Feedback based on the normal Logitech Force Feedback code and FF-Memless. Currently only supports the FF_CONSTANT effect although the joystick appears to support additional non-standard ones.

HID: lg4ff - Fix misleading info in Kconfig The description of lg4ff driver has to be changed to reflect the fact that the driver now handles a lot more Logitech wh the Wii.

#ifdef CONFIG_LOGIWHEELS_FF
HID: hid-lg4ff: Adjust X axis input value accordingly to selected range. Range limiting command for the Driving Force Pro wheel is only a FF_SPRING effect so that the wheel creates resistance when the user tries to turn it past the limit. It is however possible to overpower the FFB motors quite easily which leads to the X axis value exceeding the expected limit. This confuses games which dynamically adjust calibration using the highest/lowest min and max values reported by the wheel. Joydev device driver also doesn't take in account any changes in an axis range after the joystick device is created. This patch recalculates received ABS_X axis value so it is always in <0; 16383> range where 0 is the left limit and 16383 the right limit. Logitech driver for Windows does the same thing. As for any concerns about possible loss of precision, I compared a large set of raw/adjusted values generated by "mult_frac" to values returned by the Windows driver and I got a 100% match. Other Logitech wheels will probably need a similar fix, but I currently lack the information needed to write one.

HID: Add support for Logitech Speed Force Wireless gaming wheel The following patch adds support for the Logitech Speed Force Wireless gaming wheel. Originally designed for the WII console. Details on the protocol: http://wiibrew.org/wiki/Logitech_USB_steering_wheel This patch relies on previous patch: "Don't Send Feature Reports on Interrupt Endpoint" Logitech as produce a very similar wheel for the PS2/PS3, it is expected that this patch could also support the PS2/PS3 wheel if the USB ID's are added and (if required) the HID descriptor is modified.

HID: lg4ff - Add range setting support and sysfs interface Wheel range of certain Logitech wheels - namely Driving Force GT, Driving Force Pro, G25 and G27 can be adjusted. Minimu is 40 degrees, maximum 900. DFGT, G25 and G27 all use a common command, DFP uses another one. Range can be set from userspace by writing to "/sys/module/hid_logitech/drivers/hid:logitech/<dev>range". The driver use list to store range of each connected wheel; it's not possible to use driver_data in hid_device struct as it's already b hig-lg driver.
