2017-07-27HID: introduce hid_is_using_ll_driverJason Gerecke1-0/+11
Although HID itself is transport-agnostic, occasionally a driver may want to interact with the low-level transport that a device is connected through. To do this, we need to know what kind of bus is in use. The first guess may be to look at the 'bus' field of the 'struct hid_device', but this field may be emulated in some cases (e.g. uhid). More ideally, we can check which ll_driver a device is using. This function introduces a 'hid_is_using_ll_driver' function and makes the 'struct hid_ll_driver' of the four most common transports accessible through hid.h.

2017-06-08HID: serialize hid_hw_open and hid_hw_closeDmitry Torokhov1-63/+9
The HID transport drivers either re-implement exactly the same logic (usbhid, i2c-hid) or forget to implement it (usbhid) which causes issues when the same device is accessed via multiple interfaces (for example input device through evdev and also hidraw). Let's muve the locking logic into HID core to make sure the serialized behavior is always enforced. Also let's uninline and move hid_hw_start() and hid_hw_stop() into hid-core as hid_hw_start() is somewhat large and do not believe we get any benefit from these two being inline.

2017-03-21HID: hiddev: reallocate hiddev's minor numberJaejoong Kim1-1/+0
We need to store the minor number each drivers. In case of hidraw, the minor number is stored stores in struct hidraw. But hiddev's minor is located in struct hid_device. The hid-core driver announces a kernel message which driver is loaded when HID device connected, but hiddev's minor number is always zero. To proper display hiddev's minor number, we need to store the minor number asked from usb core and do some refactoring work (move from hiddev.c to hiddev.h) to access hiddev in hid-core.

2017-03-21HID: remove initial reading of reports at connectBenjamin Tissoires1-1/+1
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.

2016-11-28HID: input: rework HID_QUIRK_MULTI_INPUTBenjamin Tissoires1-0/+1
The purpose of HID_QUIRK_MULTI_INPUT is to have an input device per report id. This is useful when the HID device presents several HID collections of different device types. The current implementation of hid-input creates one input node per id per type (input or output). This is problematic for the LEDs of a keyboard as they are often set through an output report. The current code creates one input node with all the keyboard keys, and one other with only the LEDs. To solve this, we use a two-passes way: - first, we initialize all input nodes and associate one per report id - then, we register all the input nodes Signed-off-by: Benjamin Tissoires <benjamin.tissoires@redhat.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>

Note that 'hidinput_calc_abs_res' expects ABS_Z (historically used by our driver to report twist) to have linear units. To ensure it calculates a resolution with the actually-angular units provided in the HID descriptor we nedd to lie and tell it we're calculating it for the (rotational) ABS_RZ axis instead.

2015-03-14power_supply: Change ownership from driver to coreKrzysztof Kozlowski1-3/+3
Change the ownership of power_supply structure from each driver implementing the class to the power supply core. The patch changes power_supply_register() function thus all drivers implementing power supply class are adjusted. Each driver provides the implementation of power supply. However it should not be the owner of power supply class instance because it is exposed by core to other subsystems with power_supply_get_by_name(). These other subsystems have no knowledge when the driver will unregister the power supply. This leads to several issues when driver is unbound - mostly because user of power supply accesses freed memory. Instead let the core own the instance of struct 'power_supply'. Other users of this power supply will still access valid memory because it will be freed when device reference count reaches 0.

2014-12-17HID: rmi: Scan the report descriptor to determine if the device is suitable ↵Andrew Duggan1-1/+3
for the hid-rmi driver On composite HID devices there may be multiple HID devices on separate interfaces, but hid-rmi should only bind to the touchpad. The previous version simply checked that the interface protocol was set to mouse. Unfortuately, it is not always the case that the touchpad has the mouse interface protocol set. This patch takes a different approach and scans the report descriptor looking for the Generic Desktop Pointer usage and the Vendor Specific Top Level Collection needed by the hid-rmi driver to interface with the device.

2014-10-01HID: wacom: implement generic HID handling for pen generic devicesBenjamin Tissoires1-0/+2
ISDv4 and v5 are plain HID devices. We can directly implement a generic HID parsing/handling and remove the need to manually add those PID in the list of supported devices. This patch implements the pen support only. The finger part will come in a later patch. To be properly notified of an .event() and a .report(), we need to force hid-core to go through the HID parsing. By default, wacom.ko binds only hidraw, so the hid parsing is not done by hid-core. When a true HID device is there, we add the flag HID_CLAIMED_DRIVER to hid->claimed which will force hid-core to parse the incoming reports. (Note that this can be easily backported by directly setting the .claimed flag to HID_CLAIMED_DRIVER even if hid-core does not support HID_CONNECT_DRIVER) Signed-off-by: Benjamin Tissoires <benjamin.tissoires@redhat.com> Acked-by: Jason Gerecke <killertofu@gmail.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>

2014-07-26Input: wacom - switch from an USB driver to a HID driverBenjamin Tissoires1-0/+5
All USB Wacom tablets are actually HID devices. For historical reasons, they are handled as plain USB devices. The current code makes more and more reference to the HID subsystem like implementing its own HID report descriptor parser to handle new devices. From the user point of view, we can transparently switch from this state to a driver handled in the HID subsystem and clean up a lot of USB specific code in the wacom.ko driver. The other benefit once the USB dependecies have been removed is that we can use a tool like uhid to make regression tests and allow further cleanup or new implementations without risking breaking current behaviors. To match the current handling of devices in wacom_wac.c, we rely on the hid_type set by usbhid. usbhid sets the hid_type to HID_TYPE_USBMOUSE when it sees a USB boot mouse protocol declared and HID_TYPE_USBNONE when the device is plain HID. There is thus a one to one matching between the list of supported devices before and after the switch from USB to HID.

2014-04-09HID: rmi: introduce RMI driver for Synaptics touchpadsBenjamin Tissoires1-0/+2
This driver add support for RMI4 over USB or I2C. The current state is that it uses its own RMI4 implementation, but once RMI4 is merged upstream, the driver will be a transport driver for the RMI4 library. Part of this driver should be considered as temporary. Most of the RMI4 processing and input handling will be deleted at some point. I based my work on Andrew's regarding its port of RMI4 over HID (see https://github.com/mightybigcar/synaptics-rmi4/tree/rmihid ) This repo presents how the driver may looks like at the end: https://github.com/mightybigcar/synaptics-rmi4/blob/rmihid/drivers/input/rmi4/rmi_hid.c Without this temporary solution, the workaround we gave to users is to disable i2c-hid, which leads to disabling the touchscreen on the XPS 11 and 12 (Haswell generation).
