2010-09-15Input: hid-input - allow mapping unknown usagesDmitry Torokhov
Currently HID layer only allows to remap keycodes for known usages, and responds with -EINVAL when user tries to map new usage code. This precludes us form relying on udev/keymap for establishing correct mappings and forces us to write dummy HID drivers responsible only for setting up keymaps. Let's allow remapping not only usages that have been set up as keys (usage->type == EV_KEY) but also yet-unmapped usages (usage->type == 0).

2010-09-12Input: wacom - request tablet data for Bamboo PensChris Bagwell
Bamboo P&T need to use second form of usb_set_report() to ask to report tablet data. With previous addition of Bamboo Touch, BTN_TOOL_TRIPLETAP is now used for both TABLETPC2FG and BAMBOO_PT types. So reduced check to match type=TABLETPC2FG. This change shows redundant check for !TABLETPC2FG in else statement.

2010-09-09Input: add support for large scancodesMauro Carvalho Chehab
Several devices use a high number of bits for scancodes. One important group is the Remote Controllers. Some new protocols like RC-6 define a scancode space of 64 bits. The current EVIO[CS]GKEYCODE ioctls allow replace the scancode/keycode translation tables, but it is limited to up to 32 bits for scancode. Also, if userspace wants to clean the existing table, replacing it by a new one, it needs to run a loop calling the ioctls over the entire sparse scancode space. To solve those problems, this patch extends the ioctls to allow drivers handle scancodes up to 32 bytes long (the length could be extended in the future should such need arise) and allow userspace to query and set scancode to keycode mappings not only by scancode but also by index. Compatibility code were also added to handle the old format of EVIO[CS]GKEYCODE ioctls. Folded fixes by: - Dan Carpenter: locking fixes for the original implementation - Jarod Wilson: fix crash when setting keycode and wiring up get/set handlers in original implementation. - Dmitry Torokhov: rework to consolidate old and new scancode handling, provide options to act either by index or scancode.

2010-09-05Input: wacom - add a quirk for low resolution Bamboo devicesHenrik Rydberg
The Bamboo Touch reports a sub-screen resolution of 480x320. The signal-to-noise ratio is only about 100, so filtering is needed in order to reduce the jitter to a usable level. However, the low resolution leads to round-off errors in the EWMA filter, resulting in extremely jerky pointer motion. This patch explicitly sets a higher resolution for those devices, and tells this to the completion handler via a low-resolution quirk.

2010-09-01Staging: mrst-touchscreen - fix channel allocationArjan van de Ven
The touch screen driver tries to find a range of free channels (which are an array of bytes), by scanning for the "end of used channel" marker. However it tries to be WAAAAY too smart and does 32 bit logic on 8 bit quantities, and in the process completely gets it wrong (repeatedly read the same register instead of incrementing in the loop, assuming that if any of the 4 bytes in the 32 byte quantity is free, all four are free, returning the channel number divided by 4 rather than the actual first free channel number) On the setting side, the same mistakes are made by and large; changed this to just use the byte SCU write functions.... With these fixes we go from a completely non detected touchscreen to something that appears to completely get detected.
