2017-03-30HID: wacom: call _query_tablet_data() for BAMBOO_TOUCHAaron Armstrong Skomra
Commit a544c619a54b ("HID: wacom: do not attempt to switch mode while in probe") introduces delayed work for querying (setting the mode) on all tablets. Bamboo Touch (056a:00d0) has a ghost interface which claims to be a pen device. Though this device can be removed, we have to set the mode on the ghost pen interface before we remove it. After the aforementioned delay was introduced the device was being removed before the mode setting could be executed.

2017-03-30HID: wacom: Don't add ghost interface as shared dataAaron Armstrong Skomra
A previous commit (below) adds a check for already probed interfaces to Wacom's matching heuristic. Unfortunately this causes the Bamboo Pen (CTL-460) to match itself to its 'ghost' touch interface. After subsequent changes to the driver this match to the ghost causes the kernel to crash. This patch avoids calling wacom_add_shared_data() for the BAMBOO_PEN's ghost touch interface.

2017-03-30HID: asus: change mapping from KEY_WLAN to KEY_RFKILLMatjaz Hegedic
The input mapping code incorrectly maps the Airplane Mode button to KEY_WLAN, which stands for WiFi toggle, but doesn't affect Bluetooth (and other active radios) which is expected behavior for Airplane Mode. The fix replaces KEY_WLAN with the more appropriate KEY_RFKILL. The declared usage code 0x88 corresponds to Airplane Mode button on all keyboards handled by hid-asus (I2C netbook keyboards and USB RoG series keyboards), so the fix doesn't introduce any inconsistencies across different models.

2017-03-30HID: asus: ignore declared dummy usagesMatjaz Hegedic
Keyboards handled by hid-asus declare special key functions using a vendor-specific page, however, alongside legitimate key functions, dummy usages with seemingly arbitrary values are also declared and can lead to keyboards being detected as pointer devices by some software (such as X.org). In addition, for the I2C keyboard volume controls are separately declared in a Consumer Usage page, with the same dummy usage problem. The fix in 1989dada7ce0 ("HID: input: ignore System Control application usages if not System Controls") does not mitigate the problem described above, therefore dummy usages need to be ignored in the driver itself. This fix properly ignores dummy usages and introduces a quirk for custom handling of the Consumer Usages on the I2C keyboard.

2017-03-30HID: asus: fix and generalize ambiguous preprocessor macrosMatjaz Hegedic
Before commits a1cbda7a65a7a ("HID: asus: drop dependency on I2C_HID") and 64a403c6555fd ("HID: asus: support Republic Of Gamers special keys") hid-asus only pertained to a single I2C keyboard model found in ASUS X205TA, F205TA, & X200HA. The aforementioned commits expanded this support to other ASUS laptop keyboard models. In order to clarify that existing keyboard and touchpad quirks only apply to the I2C devices, and not ASUS keyboards in general, I2C HID IDs and their corresponding quirk sets have been renamed. In addition, the latter commit introduced special key handling, which also applies to the I2C keyboard, not just Republic of Gamers series. Therefore, the rog_map_key_clear() macro is renamed to asus_map_key_clear() for the sake of generality.

The hid-core driver announces a kernel message which driver is loaded when HID device connected, but hiddev's minor number is always zero.

2017-03-21HID: sony: Remove report descriptor fixup for DS4Roderick Colenbrander
The DS4 in BT mode sends initial input reports through report 1, which is described in the HID report descriptors. When activated after sending a certain feature report, the device uses report 17. Currently the hid-sony driver fixes up the BT HID report descriptors, so the HID layer can manage input reports for report 17. We think it is best to eliminate this fixup and do the handling ourselves, which is what this patch does. The main motivation is that there are various users of DS4 through hidraw, including various cross-platform applications/games, which have their own HID parsing across Linux/Win/OSX. Due to the fixup the descriptors differ, which is causing pain for many developers including major game publishers (who reached out privately). Without the fixup, the Windows titles also have a fighting chance for working on Wine, which provides HID support now. Overall it felt best because of these reasons to remove the fixup.

2017-03-21HID: sony: Report DS4 motion sensors through a separate deviceRoderick Colenbrander
The DS4 motion sensors are currently mapped by the hid-core driver to non-existing axes in between ABS_MISC and ABS_MT_SLOT, because the device already exhausted ABS_X-ABS_RZ. For a part the mapping by hid-core is accomplished by a fixup in hid-sony as the motion axes actually use vendor specific usage pages. This patch makes the DS4 use a separate input device for the motion sensors and reports acceleration data through ABS_X-ABS_Z and gyroscope data through ABS_RX-ABS_RZ. In addition it extends the event spec to allow gyroscope data through ABS_RX-ABS_RZ when INPUT_PROP_ACCELEROMETER is set.

2017-03-21HID: remove initial reading of reports at connectBenjamin Tissoires
It looks like a bunch of devices do not like to be polled for their reports at init time. When you look into the details, it seems that for those that are requiring the quirk HID_QUIRK_NO_INIT_REPORTS, the driver fails to retrieve part of the features/inputs while others (more generic) work. IMO, it should be acceptable to remove the need for the quirk in the general case. On the small amount of cases where we actually need to read the current values, the driver in charge (hid-mt or wacom) already retrieves the features manually. There are 2 cases where we might need to retrieve the reports at init: 1. hiddev devices with specific use-space tool 2. a device that would require the driver to fetch a specific feature/input at plug For case 2, I have seen this a few time on hid-multitouch. It is solved in hid-multitouch directly by fetching the feature. I hope it won't be too common and this can be solved on a per-case basis (crossing fingers). For case 1, we moved the implementation of HID_QUIRK_NO_INIT_REPORTS in hiddev. When somebody starts calling ioctls that needs an initial update, the hiddev device will fetch the initial state of the reports to mimic the current behavior. This adds a small amount of time during the first HIDIOCGUSAGE(S), but it should be acceptable in most cases. To keep the currently known broken devices, we have to keep around HID_QUIRK_NO_INIT_REPORTS, but the scope will only be for hiddev. Note that I don't think hidraw would be affected and I checked that the FF drivers that need to interact with the report fields are all using output reports, which are not initialized by usbhid_init_reports(). NO_INIT_INPUT_REPORTS is then replaced by HID_QUIRK_NO_INIT_REPORTS: there is no point keeping it for just one device.

2017-03-21HID: clamp input to logical range if no null stateTomasz Kramkowski
This patch fixes an issue in drivers/hid/hid-input.c where values outside of the logical range are not clamped when "null state" bit of the input control is not set. This was discussed on the lists [1] and this change stems from the fact due to the ambiguity of the HID specification it might be appropriate to follow Microsoft's own interpretation of the specification. As noted in Microsoft's documentation [2] in the section titled "Required HID usages for digitizers" it is noted that values reported outside the logical range "will be considered as invalid data and the value will be changed to the nearest boundary value (logical min/max)." This patch fixes an issue where the (1292:4745) Innomedia INNEX GENESIS/ATARI reports out of range values for its X and Y axis of the DPad which, due to the null state bit being unset, are forwarded to userspace as is. Now these values will get clamped to the logical range before being forwarded to userspace. This device was also used to test this patch. This patch expands on commit 3f3752705dbd ("HID: reject input outside logical range only if null state is set").

Jonathan mentioned just what I thought in a new project recently. It dosen't make sense to discard 1 bit width/height in general case according to the spec in multi-touch-protocol.txt so I would like to make a slight change here.

2017-03-06HID: reject input outside logical range only if null state is setValtteri Heikkilä
This patch fixes an issue in drivers/hid/hid-input.c where USB HID control null state flag is not checked upon rejecting inputs outside logical minimum-maximum range. The check should be made according to USB HID specification 1.11, section 6.2.2.5, p.31. The fix will resolve issues with some game controllers, such as: https://bugzilla.kernel.org/show_bug.cgi?id=68621 [tk@the-tk.com: shortened and fixed spelling in commit message] Signed-off-by: Valtteri Heikkilä <rnd@nic.fi> Signed-off-by: Tomasz Kramkowski <tk@the-tk.com> Acked-By: Benjamin Tissoires <benjamin.tissoires@redhat.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
2017-03-06HID: i2c-hid: support regulator power on/offBrian Norris
On some boards, we need to enable a regulator before using the HID, and it's also nice to save power in suspend by disabling it. Support an optional "vdd-supply" and a companion initialization delay.

2017-03-06HID: Add quirk driver for NTI USB-SUN adapterJonathan Tomer
These adapters allow pre-USB Sun keyboards to be connected to USB-only machines, but include the wrong maximum keycode in their report descriptor, making most of the keys present on Sun keyboards but not 101-key PC keyboards nonfunctional. This patch implements a quirk that overrides the maximum keycode in the report descriptor.
