This adds a driver for the Pegasus Notetaker Pen. When connected, this uses the Pen as an input tablet. This device was sold in various different brandings, for example "Pegasus Mobile Notetaker M210", "Genie e-note The Notetaker", "Staedtler Digital ballpoint pen 990 01", "IRISnotes Express" or "NEWLink Digital Note Taker". Here's an example, so that you know what we are talking about: http://www.genie-online.de/genie-e-note-2/ https://pegatech.blogspot.com/ seems to be a remaining official resource. This device can also transfer saved (offline recorded handwritten) data and there are userspace programs that do this, see https://launchpad.net/m210 (Well, alternatively there are really fast scanners out there :) It's *really* fun to use as an input tablet though! So let's support this for everybody. Signed-off-by:

For devices that are incapable of reporting per-contact distance and can only report ABS_DISTANCE, just distance is not enough for upper layers of OS to determine whether contact is leaving the area or if it is continuing hovering, we need BTN_TOOL_FINGER for that: Contact State Inactive Hovering Active (far away) (inside hover area) (touching surface) BTN_TOUCH 0 0 1 BTN_TOOL_FINGER 0 1 1 ABS_DISTANCE N/A 1 0 Signed-off-by:

We should not be ignoring -EPROBE_DEFER reported by devm_gpiod_get_optional(), but report it as any other error to the upper layers. While we are at it simplify check for the presence of reset GPIO and instead of using IS_ERR_OR_NULL just use boolean. Also do not return -ENOMEM from suspend handler when the device in bootloader mode as that does not make sense and switch to -EBUSY instead. Reported-by:

This change creates a second input device which will handle input from a Surface Pen. The Surface Pen supplies a different packet header than touch events, so it is simple to handle one or the other. This patch handles both the newer Surface Pen with one button, and the older variant with a second button to switch to Eraser mode. Signed-off-by:

This is a basic driver for the Surface 3. I am not so sure it will work with any firmwares as most values are encoded, but given that I only have access to my current device with its firmware and I don't have the datasheet, it should be OK for now. The Surface Pen is not supported (if it is supposed to be). I'll work on this when I get one. Tested-by:

Commit 4369c64c ("Input: Send events one packet at a time") significantly reduced amount of entropy input core was feeding to the rest of the system, because only the very first event in the event block would be used as source of entropy. With this change we will be calling add_input_randomness() for every event that is not filtered by the input core as a duplicate. In addition, all EV_SYN events are ignored. Acked-by:

The CM109 driver reported key press events of volume up / down and record / playback mute buttons, but no release events. Report those events properly by handling volume and mute keys seperately. For the record and playback mute buttons, only presses are registered by the CM109, therefore simulate press-n-release. This fixes the volume control buttons of various USB headsets. Signed-off-by:

Instead of doing the dance with macro that either resolves to a pointer or NULL, let's switch to using SIMPLE_DEV_PM_OPS(). Also let's mark suspend and resume methods as __maybe_unused instead of guarding them with an #ifdef and rely on linker to drop unused code. Doing so should allow better compile coverage.
