HID: fix unit exponent parsing

2012-11-15T09:07:55+00:00

HID spec details special values for the HID field unit exponent.
Basically, the range [0x8..0xf] correspond to [-8..-1], so this is
a standard two's complement on a half-byte.

HID: round return value of hidinput_calc_abs_res

2012-11-15T09:06:56+00:00

hidinput_calc_abs_res should return the closest int in the division
instead of the floor.
On a device with a logical_max of 3008 and a physical_max of 255mm,
previous implementation gave a resolution of 11 instead of 12.
With 11, user-space computes a physical size of 273.5mm and the
round_closest results gives 250.6mm.
The old implementation introduced an error of 2cm in this example.

HID: export hidinput_calc_abs_res

2012-11-15T09:06:28+00:00

Exporting the function allows us to calculate the resolution in third
party drivers like hid-multitouch.
This patch also complete the function with additional valid axes.

HID: fix incorrect handling of devices with high button count

2012-10-31T15:03:32+00:00

Button names for USB gamepads are currently assigned incorrectly, as the evdev
code assigned to buttons is "BTN_GAMEPAD + code", which on devices with more
then 16 buttons bleeds over into button names reserved for graphic tablets
(BTN_TOOL_PEN, etc.). This causes problems further down the line as the device
are now no longer detected as joystick. This patch fixes that by assigning
buttons outside the range to BTN_TRIGGER_HAPPY (as is already the case for USB
joysticks).

Furthermore this patch corrects the assignment to BTN_TRIGGER_HAPPY, as
currently the first button over 16 is assigned to BTN_TRIGGER_HAPPY17 (i.e.
BTN_TRIGGER_HAPPY+0x10) not BTN_TRIGGER_HAPPY.

HID: Add an input configured notification callback

2012-09-19T17:50:20+00:00

A hid device may create several input devices, and a driver may need
to prepare or finalize the configuration per input device. Currently,
there is no sane way for a driver to know when a device has been
configured. This patch adds a callback providing that information.
