2019-05-16T17:41:19+00:00

[ Upstream commit c01908a14bf735b871170092807c618bb9dae654 ] According to HUT 1.12 usage 0xb5 from the generic desktop page is reserved for switching between external and internal display, so let's add the mapping. Signed-off-by: Dmitry Torokhov Signed-off-by: Sasha Levin

HID: input: add mapping for keyboard Brightness Up/Down/Toggle keys

2019-05-16T17:41:19+00:00

[ Upstream commit 7975a1d6a7afeb3eb61c971a153d24dd8fa032f3 ] According to HUTRR73 usages 0x79, 0x7a and 0x7c from the consumer page correspond to Brightness Up/Down/Toggle keys, so let's add the mappings. Signed-off-by: Dmitry Torokhov Signed-off-by: Sasha Levin

HID: input: add mapping for Expose/Overview key

2019-05-16T17:41:19+00:00

[ Upstream commit 96dd86871e1fffbc39e4fa61c9c75ec54ee9af0f ] According to HUTRR77 usage 0x29f from the consumer page is reserved for the Desktop application to present all running user’s application windows. Linux defines KEY_SCALE to request Compiz Scale (Expose) mode, so let's add the mapping. Signed-off-by: Dmitry Torokhov Signed-off-by: Sasha Levin

[ Upstream commit ce856634af8cda3490947df8ac1ef5843e6356af ] According to HUTRR89 usage 0x1cb from the consumer page was assigned to allow launching desktop-aware assistant application, so let's add the mapping. Signed-off-by: Dmitry Torokhov Signed-off-by: Jiri Kosina Signed-off-by: Sasha Levin

HID: input: Ignore battery reported by Symbol DS4308

2018-12-13T08:16:10+00:00

[ Upstream commit 0fd791841a6d67af1155a9c3de54dea51220721e ] The Motorola/Zebra Symbol DS4308-HD is a handheld USB barcode scanner which does not have a battery, but reports one anyway that always has capacity 2. Let's apply the IGNORE quirk to prevent it from being treated like a power supply so that userspaces don't get confused that this accessory is almost out of power and warn the user that they need to charge their wired barcode scanner.

HID: core: fix grouping by application

2018-09-04T19:31:43+00:00

commit f07b3c1da92d ("HID: generic: create one input report per application type") was effectively the same as MULTI_INPUT: hidinput->report was never set, so hidinput_match_application() always returned null. Fix that by testing against the real application. Note that this breaks some old eGalax touchscreens that expect MULTI_INPUT instead of HID_QUIRK_INPUT_PER_APP. Enable this quirk for backward compatibility on all non-Win8 touchscreens. link: https://bugzilla.kernel.org/show_bug.cgi?id=200847 link: https://bugzilla.kernel.org/show_bug.cgi?id=200849 link: https://bugs.archlinux.org/task/59699 link: https://github.com/NixOS/nixpkgs/issues/45165 Cc: stable@vger.kernel.org # v4.18+ Signed-off-by: Benjamin Tissoires Signed-off-by: Jiri Kosina

HID: input: enable Totem on the Dell Canvas 27

2018-07-17T13:33:47+00:00

The Dell Canvas 27 has a tool that can be put on the surface and acts as a dial. The firmware processes the detection of the tool and forward regular HID reports with X, Y, Azimuth, rotation, width/height. The firmware also exports Contact ID, Countact Count which may hint that several totems can be used at the same time (the FW only supports one). We can tell that MT_TOOL_DIAL will be reported by setting the min/max of ABS_MT_TOOL_TYPE to MT_TOOL_DIAL. This tool is aimed at being used by the system and not the applications, so the user space processing should not go through the regular touch inputs. We set INPUT_PROP_DIRECT which applies ID_INPUT_TOUCHSCREEN to this new type of devices, but we will counter this for the time being with the special udev hwdb entry mentioned above.

HID: input: append a suffix matching the application

2018-04-26T12:17:31+00:00

Given that we create one input node per application, we should name the input node accordingly to not lose userspace. Signed-off-by: Benjamin Tissoires Signed-off-by: Jiri Kosina
