2020-11-19HID: logitech-dj: Fix Dinovo Mini when paired with a MX5x00 receiverHans de Goede2-0/+26
Some users are pairing the Dinovo keyboards with the MX5000 or MX5500 receivers, instead of with the Dinovo receivers. The receivers are mostly the same (and the air protocol obviously is compatible) but currently the Dinovo receivers are handled by hid-lg.c while the MX5x00 receivers are handled by logitech-dj.c. When using a Dinovo keyboard, with its builtin touchpad, through logitech-dj.c then the touchpad stops working because when asking the receiver for paired devices, we get only 1 paired device with a device_type of REPORT_TYPE_KEYBOARD. And since we don't see a paired mouse, we have nowhere to send mouse-events to, so we drop them. Extend the existing fix for the Dinovo Edge for this to also cover the Dinovo Mini keyboard and also add a mapping to logitech-hidpp for the Media key on the Dinovo Mini, so that that keeps working too.

2020-11-19HID: logitech-dj: Fix an error in mse_bluetooth_descriptorHans de Goede1-1/+1
Fix an error in the mouse / INPUT(2) descriptor used for quad/bt2.0 combo receivers. Replace INPUT with INPUT (Data,Var,Abs) for the field for the 4 extra buttons which share their report-byte with the low-res hwheel. This is likely a copy and paste error. I've verified that the new 0x81, 0x02 value matches both the mouse descriptor for the currently supported MX5000 / MX5500 receivers, as well as the INPUT(2) mouse descriptors for the Dinovo receivers for which support is being worked on.

2020-11-12HID: Add Logitech Dinovo Edge battery quirkHans de Goede2-0/+4
The battery status is also being reported by the logitech-hidpp driver, so ignore the standard HID battery status to avoid reporting the same info twice. Note the logitech-hidpp battery driver provides more info, such as properly differentiating between charging and discharging. Also the standard HID battery info seems to be wrong, reporting a capacity of just 26% after fully charging the device.

2020-11-12HID: logitech-hidpp: Add HIDPP_CONSUMER_VENDOR_KEYS quirk for the Dinovo EdgeHans de Goede1-0/+6
Like the MX5000 and MX5500 quad/bluetooth keyboards the Dinovo Edge also needs the HIDPP_CONSUMER_VENDOR_KEYS quirk for some special keys to work. Specifically without this the "Phone" and the 'A' - 'D' Smart Keys do not send any events. In addition to fixing these keys not sending any events, adding the Bluetooth match, so that hid-logitech-hidpp is used instead of the generic HID driver, also adds battery monitoring support when the keyboard is connected over Bluetooth.

2020-11-12HID: logitech-dj: Handle quad/bluetooth keyboards with a builtin trackpadHans de Goede1-0/+19
Some quad/bluetooth keyboards, such as the Dinovo Edge (Y-RAY81) have a builtin touchpad. In this case when asking the receiver for paired devices, we get only 1 paired device with a device_type of REPORT_TYPE_KEYBOARD. This means that we do not instantiate a second dj_hiddev for the mouse (as we normally would) and thus there is no place for us to forward the mouse input reports to, causing the touchpad part of the keyboard to not work. There is no way for us to detect these keyboards, so this commit adds an array with device-ids for such keyboards and when a keyboard is on this list it adds STD_MOUSE to the reports_supported bitmap for the dj_hiddev created for the keyboard fixing the touchpad not working. Using a list of device-ids for this is not ideal, but there are only very few such keyboards so this should be fine. Besides the Dinovo Edge, other known wireless Logitech keyboards with a builtin touchpad are: * Dinovo Mini (TODO add its device-id to the list) * K400 (uses a unifying receiver so is not affected) * K600 (uses a unifying receiver so is not affected) Cc: stable@vger.kernel.org BugLink: https://bugzilla.redhat.com/show_bug.cgi?id=1811424 Fixes: f2113c3020ef ("HID: logitech-dj: add support for Logitech Bluetooth Mini-Receiver") Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Benjamin Tissoires <benjamin.tissoires@redhat.com>

2020-11-05HID: mcp2221: Fix GPIO output handlingLars Povlsen1-9/+39
The mcp2221 driver GPIO output handling has has several issues. * A wrong value is used for the GPIO direction. * Wrong offsets are calculated for some GPIO set value/set direction operations, when offset is larger than 0. This has been fixed by introducing proper manifest constants for the direction encoding, and using 'offsetof' when calculating GPIO register offsets. The updated driver has been tested with the Sparx5 pcb134/pcb135 board, which has the mcp2221 device with several (output) GPIO's.

2020-10-29HID: i2c-hid: Put ACPI enumerated devices in D3 on shutdownHans de Goede1-0/+9
The i2c-hid driver would quietly fail to probe the i2c-hid sensor-hub with an ACPI device-id of SMO91D0 every other boot. Specifically, the i2c_smbus_read_byte() "Make sure there is something at this address" check would fail every other boot. It seems that the BIOS does not properly reset/power-cycle the device leaving it in a confused state where it refuses to respond to i2c-xfers. On boots where probing the device failed, the driver-core puts the device in D3 after the probe-failure, which causes the probe to succeed the next boot. Putting the device in D3 from the shutdown-handler fixes the sensors not working every other boot. This has been tested on both a Lenovo Miix 2-10 and a Dell Venue 8 Pro 5830 both of which use an i2c-hid sensor-hub with an ACPI id of SMO91D0. Note that it is safe to call acpi_device_set_power() with a NULL pointer as first argument, so on none ACPI enumerated devices this change is a no-op.

2020-10-23HID: cypress: Support Varmilo Keyboards' media hotkeysFrank Yang2-5/+41
The Varmilo VA104M Keyboard (04b4:07b1, reported as Varmilo Z104M) exposes media control hotkeys as a USB HID consumer control device, but these keys do not work in the current (5.8-rc1) kernel due to the incorrect HID report descriptor. Fix the problem by modifying the internal HID report descriptor. More specifically, the keyboard report descriptor specifies the logical boundary as 572~10754 (0x023c ~ 0x2a02) while the usage boundary is specified as 0~10754 (0x00 ~ 0x2a02). This results in an incorrect interpretation of input reports, causing inputs to be ignored. By setting the Logical Minimum to zero, we align the logical boundary with the Usage ID boundary. Some notes: * There seem to be multiple variants of the VA104M keyboard. This patch specifically targets 04b4:07b1 variant. * The device works out-of-the-box on Windows platform with the generic consumer control device driver (hidserv.inf). This suggests that Windows either ignores the Logical Minimum/Logical Maximum or interprets the Usage ID assignment differently from the linux implementation; Maybe there are other devices out there that only works on Windows due to this problem?

2020-10-22HID: ite: Replace ABS_MISC 120/121 events with touchpad on/off keypressesHans de Goede1-1/+60
The usb-hid keyboard-dock for the Acer Switch 10 SW5-012 model declares an application and hid-usage page of 0x0088 for the INPUT(4) report which it sends. This reports contains 2 8-bit fields which are declared as HID_MAIN_ITEM_VARIABLE. The keyboard-touchpad combo never actually generates this report, except when the touchpad is toggled on/off with the Fn + F7 hotkey combo. The toggle on/off is handled inside the keyboard-dock, when the touchpad is toggled off it simply stops sending events. When the touchpad is toggled on/off an INPUT(4) report is generated with the first content byte set to 120/121, before this commit the kernel would report this as ABS_MISC 120/121 events. Patch the descriptor to replace the HID_MAIN_ITEM_VARIABLE with HID_MAIN_ITEM_RELATIVE (because no key-presss release events are send) and add mappings for the 0x00880078 and 0x00880079 usages to generate touchpad on/off key events when the touchpad is toggled on/off.

2020-09-29PCI/PM: Rename pci_dev.d3_delay to d3hot_delayKrzysztof Wilczyński1-1/+1
PCI devices support two variants of the D3 power state: D3hot (main power present) D3cold (main power removed). Previously struct pci_dev contained: unsigned int d3_delay; /* D3->D0 transition time in ms */ unsigned int d3cold_delay; /* D3cold->D0 transition time in ms */ "d3_delay" refers specifically to the D3hot state. Rename it to "d3hot_delay" to avoid ambiguity and align with the ACPI "_DSM for Specifying Device Readiness Durations" in the PCI Firmware spec r3.2, sec 4.6.9. There is no change to the functionality.

2020-09-28HID: hyperv: Use VMBUS_RING_SIZE() for ringbuffer sizesBoqun Feng1-2/+2
For a Hyper-V vmbus, the size of the ringbuffer has two requirements: 1) it has to take one PAGE_SIZE for the header 2) it has to be PAGE_SIZE aligned so that double-mapping can work VMBUS_RING_SIZE() could calculate a correct ringbuffer size which fulfills both requirements, therefore use it to make sure vmbus work when PAGE_SIZE != HV_HYP_PAGE_SIZE (4K). Note that since the argument for VMBUS_RING_SIZE() is the size of payload (data part), so it will be minus 4k (the size of header when PAGE_SIZE = 4k) than the original value to keep the ringbuffer total size unchanged when PAGE_SIZE = 4k.

2020-09-25HID: wacom: Avoid entering wacom_wac_pen_report for pad / batteryJason Gerecke1-1/+3
It has recently been reported that the "heartbeat" report from devices like the 2nd-gen Intuos Pro (PTH-460, PTH-660, PTH-860) or the 2nd-gen Bluetooth-enabled Intuos tablets (CTL-4100WL, CTL-6100WL) can cause the driver to send a spurious BTN_TOUCH=0 once per second in the middle of drawing. This can result in broken lines while drawing on Chrome OS. The source of the issue has been traced back to a change which modified the driver to only call `wacom_wac_pad_report()` once per report instead of once per collection. As part of this change, pad-handling code was removed from `wacom_wac_collection()` under the assumption that the `WACOM_PEN_FIELD` and `WACOM_TOUCH_FIELD` checks would not be satisfied when a pad or battery collection was being processed. To be clear, the macros `WACOM_PAD_FIELD` and `WACOM_PEN_FIELD` do not currently check exclusive conditions. In fact, most "pad" fields will also appear to be "pen" fields simply due to their presence inside of a Digitizer application collection. Because of this, the removal of the check from `wacom_wac_collection()` just causes pad / battery collections to instead trigger a call to `wacom_wac_pen_report()` instead. The pen report function in turn resets the tip switch state just prior to exiting, resulting in the observed BTN_TOUCH=0 symptom. To correct this, we restore a version of the `WACOM_PAD_FIELD` check in `wacom_wac_collection()` and return early. This effectively prevents pad / battery collections from being reported until the very end of the report as originally intended.

2020-09-09HID: i2c-hid: Prefer asynchronous probeDouglas Anderson1-0/+1
Adding printouts to the i2c_hid_probe() function shows that it takes quite some time. It used to take about 70 ms, but after commit eef4016243e9 ("HID: i2c-hid: Always sleep 60ms after I2C_HID_PWR_ON commands") it takes about 190 ms. This is not tons of time but it's not trivial. Because we haven't yet specified that we'd prefer asynchronous probe for this driver then, if the driver is builtin to the kernel, we'll wait for this driver to finish before we start probes for more drivers. Let's set the flag to enable asynchronous for this driver so that other drivers aren't blocked from probing until we finish. Since this driver can be configured as a module and modules are always asynchronously probed this is quite a safe change and will benefit anyone who has a reason to build this driver into the kernel instead of using it as a module.

2020-09-09HID: ite: Add USB id match for Acer One S1003 keyboard dockHans de Goede2-0/+5
The Acer One S1003 2-in-1 keyboard dock uses a Synaptics S910xx touchpad which is connected to an ITE 8910 USB keyboard controller chip. This keyboard has the same quirk for its rfkill / airplane mode hotkey as other keyboards with ITE keyboard chips, it only sends a single release event when pressed and released, it never sends a press event. This commit adds this keyboards USB id to the hid-ite id-table, fixing the rfkill key not working on this keyboard. Note that like for the Acer Aspire Switch 10 (SW5-012) the id-table entry matches on the HID_GROUP_GENERIC generic group so that hid-ite only binds to the keyboard interface and the mouse/touchpad interface is left untouched so that hid-multitouch can bind to it.

This code doesn't check if "settings->startup_profile" is within bounds and that could result in an out of bounds array access. What the code does do is it checks if the settings can be written to the firmware, so it's possible that the firmware has a bounds check? It's safer and easier to verify when the bounds checking is done in the kernel.

2020-09-03media: rc: harmonize infrared durations to microsecondsSean Young1-5/+5
rc-core kapi uses nanoseconds for infrared durations for receiving, and microseconds for sending. The uapi already uses microseconds for both, so this patch does not change the uapi. Infrared durations do not need nanosecond resolution. IR protocols do not have durations shorter than about 100 microseconds. Some IR hardware offers 250 microseconds resolution, which is sufficient for most protocols. Better hardware has 50 microsecond resolution and is enough for every protocol I am aware off. Unify on microseconds everywhere. This simplifies the code since less conversion between microseconds and nanoseconds needs to be done.
