platform-drivers-x86 for v4.11-1

New intel_turbo_max_3 driver, providing max core frequency information to the
 scheduler. Intel PMC APL support, s0ix read API, and fixes.
 
 New Silead touchscreen platform touchscreen descriptions. Additional hotkey
 support for the intel-hid driver.
 
 New model support for dell-laptop and hp_accel.
 
 Several cleanups, especially to the fujitsu-laptop and intel_mid_powerbtn
 drivers.
 
 This tag includes the already merged branch: led_brightness_hw_changed from:
     git.kernel.org/pub/scm/linux/kernel/git/j.anaszewski/linux-leds into HEAD
 Which includes the following commit:
     7de50ae leds: class: Add new optional brightness_hw_changed attribute
 needed for the thinkpad_acpi changes noted below
 
 This is the first time a pdx86 pull request has included a merge of an immutable
 branch from another subsystem, as we have previously either waited for the
 dependency to be merged, or asked the other maintainer to merge dependent
 changes. As this included three patches specifically to thinkpad_acpi, we
 decided to try the merge and apply model.

  - Call led_classdev_notify_brightness_hw_changed on kbd brightness change
  - Use brightness_set_blocking callback for LEDs
  - Stop setting led_classdev brightness directly
 
 acer-wmi:
  - add another KEY_WLAN keycode
  - Inform firmware that RF Button Driver is active
  - setup accelerometer when machine has appropriate notify event
 
 asus-wireless:
  - Fix indentation
  - Use per-HID HSWC parameters
 
 intel_pmc_ipc:
  - Add APL PMC PCI Id
  - read s0ix residency API
  - Remove unused iTCO_version variable
 
 alienware-wmi:
  - Remove header duplicate
 
 intel_pmc_core:

 fujitsu-laptop:
  - make hotkey handling functions more similar
  - break up complex loop condition
  - move keycode processing to separate functions
  - decrease indentation in acpi_fujitsu_hotkey_notify()
  - simplify logolamp_get()
  - rework logolamp_set() to properly handle errors
  - set default trigger for radio LED to rfkill-any
 
 dell-smbios:
