Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jikos/hid
Pull HID subsystem updates from Jiri Kosina: - The need for HID_QUIRK_NO_INIT_REPORTS per-device quirk has been growing dramatically during past years, so the time has come to switch over the default, and perform the pro-active reading only in cases where it's really needed (multitouch, wacom). The only place where this behavior is (in some form) preserved is hiddev so that we don't introduce userspace-visible change of behavior. From Benjamin Tissoires - HID++ support for power_supply / baterry reporting. From Benjamin Tissoires and Bastien Nocera - Vast improvements / rework of DS3 and DS4 in Sony driver. From Roderick Colenbrander - Improvment (in terms of getting closer to the Microsoft's interpretation of slightly ambiguous specification) of logical range interpretation in case null-state is set in the rdesc. From Valtteri Heikkilä and Tomasz Kramkowski - A lot of newly supported device IDs and small assorted fixes * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jikos/hid: (71 commits) HID: usbhid: Add HID_QUIRK_NOGET for Aten CS-1758 KVM switch HID: asus: support backlight on USB keyboards HID: wacom: Move wacom_remote_irq and wacom_remote_status_irq HID: wacom: generic: sync pad events only for actual packets HID: sony: remove redundant check for -ve err HID: sony: Make sure to unregister sensors on failure HID: sony: Make DS4 bt poll interval adjustable HID: sony: Set proper bit flags on DS4 output report HID: sony: DS4 use brighter LED colors HID: sony: Improve navigation controller axis/button mapping HID: sony: Use DS3 MAC address as unique identifier on USB HID: logitech-hidpp: add a sysfs file to tell we support power_supply HID: logitech-hidpp: enable HID++ 1.0 battery reporting HID: logitech-hidpp: add support for battery status for the K750 HID: logitech-hidpp: battery: provide CAPACITY_LEVEL HID: logitech-hidpp: rename battery level into capacity HID: logitech-hidpp: battery: provide ONLINE property HID: logitech-hidpp: notify battery on connect HID: logitech-hidpp: return an error if the queried feature is not present HID: logitech-hidpp: create the battery for all types of HID++ devices ...

+Some devices may support additional optional properties to help with, e.g.,
+power sequencing. The following properties can be supported by one or more
+device-specific compatible properties, which should be used in addition to the
+"hid-over-i2c" string.

+- vdd-supply: phandle of the regulator that provides the supply voltage.
+- post-power-on-delay-ms: time required by the device after enabling its regulators
