Merge tag 'platform-drivers-x86-v4.8-1' of git://git.infradead.org/users/dvhart/linux-platform-drivers-x86
Pull x8 platform driver updates from Darren Hart:
"Several new quirks and tweaks for new platforms to existing laptop
drivers. A new ACPI virtual power button driver, similar to the
intel-hid driver. A rework of the dell keymap, using a single sparse
keymap for all machines. A few fixes and cleanups.
Summary:
intel-vbtn:
- new driver for Intel Virtual Button
intel_pmc_core:
- Convert to DEFINE_DEBUGFS_ATTRIBUTE
fujitsu-laptop:
- Rework brightness of eco led
asus-wmi:
- Add quirk_no_rfkill_wapf4 for the Asus X456UA
- Add quirk_no_rfkill_wapf4 for the Asus X456UF
- Add quirk_no_rfkill for the Asus Z550MA
- Add quirk_no_rfkill for the Asus U303LB
- Add quirk_no_rfkill for the Asus N552VW
- Create quirk for airplane_mode LED
- Add ambient light sensor toggle key
asus-wireless:
- Toggle airplane mode LED
intel_telemetry:
- Remove Monitor MWAIT feature dependency
intel-hid:
- Remove duplicated acpi_remove_notify_handler
fujitsu-laptop:
- Add support for eco LED
- Support touchpad toggle hotkey on Skylake-based models
- Remove unused macros
- Use module name in debug messages
hp-wmi:
- Fix wifi cannot be hard-unblocked
toshiba_acpi:
- Bump driver version and update copyright year
- Remove the position sysfs entry
- Add IIO interface for accelerometer axis data
dell-wmi:
- Add a WMI event code for display on/off
- Generate one sparse keymap for all machines
- Add information about other WMI event codes
- Sort WMI event codes and update comments
- Ignore WMI event code 0xe045"
