USB devices On composite HID devices there may be multiple HID devices on separate interfaces, but hid-rmi should only bind to the mouse interface. One example is the Dell Venue 11 Pro's keyboard dock which contains a composite USB device with a HID touchpad and HID keyboard on separate intefaces. Since the USB Vendor ID is Synaptic's, hid-core is currently trying to bind hid-rmi to all\of the HID devices.

2014-07-29HID: i2c-hid: call the hid driver's suspend and resume callbacksAndrew Duggan
Currently, the i2c-hid driver does not call the suspend, resume, and reset_resume callbacks in the hid_driver struct when those events occur. This means that HID drivers for i2c-hid devices will not be able to execute commands which may be needed during suspend or resume. One example is when a touchpad using the hid-multitouch driver gets reset by i2c-hid coming out of resume. Since the reset_resume callback never gets called the device is never put back into the correct input mode. This patch calls the suspend and resume callbacks and tries to duplicate the functionality of the usb-hid driver.

2014-07-29HID: rmi: change logging level of log messages related to unexpected reportsAndrew Duggan
Userspace tools may use hidraw to perform operations on the device from userspace while hid-rmi is bound to the device. This can cause hid-rmi to print error messages when its ->raw_event() callback gets called as the reports pass through the HID stack. In this case receiving responses which were not initiated by hid-rmi is not actually an error so the resulting error messages are incorrect and misleading. This patch changes the log messages to debug so that the messages can be turned on in the event that there is a problem and there is not a userspace tool running.

2014-07-29HID: rmi: make compututation of the address of Query 12 more carefulAndrew Duggan
There are additional queries which are optional and may not be present depending on the configuration of the firmware. Knowing which queries are present is needed to properly compute the address of Query 12 and all subsequent queries. Additional bits in Query 1 are used to indicate the presence of these optional queries.

The current implementation uses "wacom_battery" as a generic name for batteries. This prevents us to have two Wacom devices with a battery attached as the power system will complain about the name which is already registered. Use an incremental name for each battery attached.

2014-07-25Input: wacom - put a flag when the led are initializedBenjamin Tissoires
This solves a bug with the wireless receiver: - at plug, the wireless receiver does not know which Wacom device it is connected to, so it does not actually creates all the LEDs - when the tablet connects, wacom->wacom_wac.features.type is set to the proper device so that wacom_wac can understand the packets - when the receiver is unplugged, it detects that a LED should have been created (based on wacom->wacom_wac.features.type) and tries to remove it: crash when removing the sysfs group. Side effect, we can now safely call several times wacom_destroy_leds().

2014-07-25Input: wacom - switch from an USB driver to a HID driverBenjamin Tissoires
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.

2014-07-25[media] rc-core: remove protocol arraysDavid Härdeman
The basic API of rc-core used to be: dev = rc_allocate_device(); dev->x = a; dev->y = b; dev->z = c; rc_register_device(); which is a pretty common pattern in the kernel, after the introduction of protocol arrays the API looks something like: dev = rc_allocate_device(); dev->x = a; rc_set_allowed_protocols(dev, RC_BIT_X); dev->z = c; rc_register_device(); There's no real need for the protocols to be an array, so change it back to be consistent (and in preparation for the following patches).

2014-07-07HID: cp2112: fix gpio value in gpio_direction_outputAntonio Borneo
CP2112 does not offer an atomic method to set both gpio direction and value. Also it does not permit to set gpio value before putting gpio in output. In fact, accordingly to Silicon Labs AN495, Rev. 0.2, cpt. 4.4, the HID report to set gpio values "does not affect any pins that are not configured as outputs". This is confirmed on evaluation board CP2112-EK. With current driver, after execute: echo in > /sys/class/gpio/gpio248/direction echo low > /sys/class/gpio/gpio248/direction gpio output is still high. Only after a following echo low > /sys/class/gpio/gpio248/direction gpio output gets low. Fix driver by changing order of operations; first set direction then set value. The drawback of this new sequence is that we can have a pulse on gpio pin when direction is changed from input to output-low, but this cannot be avoided on current CP2112.
