2016-07-28Input: xpad - power off wireless 360 controllers on suspendCameron Gutman
When the USB wireless adapter is suspended, the controllers lose their connection. This causes them to start flashing their LED rings and searching for the wireless adapter again, wasting the controller's battery power. Instead, we will tell the controllers to power down when we suspend. This mirrors the behavior of the controllers when connected to the console itself and how the official Xbox One wireless adapter behaves on Windows.

2016-07-27Input: i8042 - break load dependency between atkbd/psmouse and i8042Dmitry Torokhov
As explained in 1407814240-4275-1-git-send-email-decui@microsoft.com we have a hard load dependency between i8042 and atkbd which prevents keyboard from working on Gen2 Hyper-V VMs. > hyperv_keyboard invokes serio_interrupt(), which needs a valid serio > driver like atkbd.c. atkbd.c depends on libps2.c because it invokes > ps2_command(). libps2.c depends on i8042.c because it invokes > i8042_check_port_owner(). As a result, hyperv_keyboard actually > depends on i8042.c. > > For a Generation 2 Hyper-V VM (meaning no i8042 device emulated), if a > Linux VM (like Arch Linux) happens to configure CONFIG_SERIO_I8042=m > rather than =y, atkbd.ko can't load because i8042.ko can't load(due to > no i8042 device emulated) and finally hyperv_keyboard can't work and > the user can't input: https://bugs.archlinux.org/task/39820 > (Ubuntu/RHEL/SUSE aren't affected since they use CONFIG_SERIO_I8042=y) To break the dependency we move away from using i8042_check_port_owner() and instead allow serio port owner specify a mutex that clients should use to serialize PS/2 command stream.

2016-07-26Input: cros_ec_keyb - cleanup use of devDouglas Anderson
In cros_ec_keyb we stored "dev" in "struct cros_ec_keyb", but this was the EC's dev pointer and not the keyboard's. Let's clean this up to make it the keyboard's dev pointer. This could be useful in future patches but also has the nice effect of changing a few printouts to include the name of the keyboard device instead of the EC device, so we will see: [ 1.224648] cros-ec-keyb ff110000.spi:ec@0:keyboard-controller: valid_keys[00] = 0x14 instead of: [ 1.224505] cros-ec-spi spi0.0: valid_keys[00] = 0x14 Signed-off-by: Douglas Anderson <dianders@chromium.org> Signed-off-by: Brian Norris <briannorris@chromium.org> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>

2016-06-24Input: vmmouse - remove port reservationSinclair Yeh
The VMWare EFI BIOS will expose port 0x5658 as an ACPI resource. This causes the port to be reserved by the APCI module as the system comes up, making it unavailable to be reserved again by other drivers, thus preserving this VMWare port for special use in a VMWare guest. This port is designed to be shared among multiple VMWare services, such as the VMMOUSE. Because of this, VMMOUSE should not try to reserve this port on its own. The VMWare non-EFI BIOS does not do this to preserve compatibility with existing/legacy VMs. It is known that there is small chance a VM may be configured such that these ports get reserved by other non-VMWare devices, and if this ever happens, the result is undefined.

2016-06-23Input: xpad - fix oops when attaching an unknown Xbox One gamepadCameron Gutman
Xbox One controllers have multiple interfaces which all have the same class, subclass, and protocol. One of the these interfaces has only a single endpoint. When Xpad attempts to bind to this interface, it causes an oops when trying initialize the output URB by trying to access the second endpoint's descriptor. This situation was avoided for known Xbox One devices by checking the XTYPE constant associated with the VID and PID tuple. However, this breaks when new or previously unknown Xbox One controllers are attached to the system. This change addresses the problem by deriving the XTYPE for Xbox One controllers based on the interface protocol before checking the interface number.
