      Pull more power management and ACPI updates from Rafael Wysocki:
       "These are fixes mostly (intel_pstate, ACPI core, ACPI EC driver,
        cpupower tool), a new CPU ID for the Intel RAPL driver and one
        intel_pstate driver improvement that didn't make it to my previous
        pull requests due to timing.
      
        Specifics:
      
         - Fix a build warning in the intel_pstate driver showing up in
           non-SMP builds (Borislav Petkov)
      
         - Change one of the intel_pstate's P-state selection parameters for
           Baytrail and Cherrytrail CPUs to significantly improve performance
           at the cost of a small increase in energy consumption (Kristen
           Carlson Accardi)
      
         - Fix a NULL pointer dereference in the ACPI EC driver due to an
           unsafe list walk in the query handler removal routine (Chris
           Bainbridge)
      
         - Get rid of a false-positive lockdep warning in the ACPI container
           hot-remove code (Rafael J Wysocki)
      
         - Prevent the ACPI device enumeration code from creating device
           objects of a wrong type in some cases (Rafael J Wysocki)
      
         - Add Skylake processors support to the Intel RAPL power capping
           driver (Brian Bian)
      
         - Drop the stale MAINTAINERS entry for the ACPI dock driver that is
           regarded as part of the ACPI core and maintained along with it now
           (Chao Yu)
      
         - Fix cpupower tool breakage caused by a library API change in libpci
           3.3.0 (Lucas Stach)"

      Pull chrome platform updates from Olof Johansson:
       "Here's a set of updates to the Chrome OS platform drivers for this
        merge window.
      
        Main new things this cycle is:
      
         - Driver changes to expose the lightbar to users.  With this, you can
           make your own blinkenlights on Chromebook Pixels.
      
         - Changes in the way that the atmel_mxt trackpads are probed.  The
           laptop driver is trying to be smart and not instantiate the devices
           that don't answer to probe.  For the trackpad that can come up in
           two modes (bootloader or regular), this gets complicated since the
           driver already knows how to handle the two modes including the
           actual addresses used.  So now the laptop driver needs to know more
           too, instantiating the regular address even if the bootloader one
           is the probe that passed.
      
         - mfd driver improvements by Javier Martines Canillas, and a few
           bugfixes from him, kbuild and myself"

      platform/chrome: chromeos_laptop - instantiate Atmel at primary address · 96cba9b0
      Dmitry Torokhov authored
      The new Atmel MXT driver expects i2c client's address contain the
      primary (main address) of the chip, and calculates the expected
      bootloader address form the primary address. Unfortunately chrome_laptop
      does probe the devices and if touchpad (or touchscreen, or both) comes
      up in bootloader mode the i2c device gets instantiated with the
      bootloader address which confuses the driver.
      
      To work around this issue let's probe the primary address first. If the
      device is not detected at the primary address we'll probe alternative
      addresses as "dummy" devices. If any of them are found, destroy the
      dummy client and instantiate client with proper name at primary address
      still.
