       "Second round of updates for the input subsystem.
      
        The BYD PS/2 protocol driver now uses absolute reporting mode and
        should behave more like other touchpads; Synaptics driver needed to
        extend one of its quirks to a newer firmware version, and a few USB
        drivers got tightened up checks for the contents of their descriptors"

      Revert "ppdev: use new parport device model" · 1701f680
      Linus Torvalds authored
      This reverts commit e7223f18.
      
      It causes problems when a ppdev tries to register before the parport
      driver has been registered with the device model. That will trigger the
      
              BUG_ON(!drv->bus->p);
      
      at drivers/base/driver.c:153. The call chain is
      
        kernel_init ->
          kernel_init_freeable ->
            do_one_initcall ->
              ppdev_init ->
                __parport_register_driver ->
                  driver_register *BOOM*

      Linus Torvalds authored
      Pull more power management and ACPI updates from Rafael Wysocki:
       "The second batch of power management and ACPI updates for v4.6.
      
        Included are fixups on top of the previous PM/ACPI pull request and
        other material that didn't make into it but still should go into 4.6.
      
        Among other things, there's a fix for an intel_pstate driver issue
        uncovered by recent cpufreq changes, a workaround for a boot hang on
        Skylake-H related to the handling of deep C-states by the platform and
        a PCI/ACPI fix for the handling of IO port resources on non-x86
        architectures plus some new device IDs and similar.
      
        Specifics:
      
         - Fix for an intel_pstate driver issue related to the handling of MSR
           updates uncovered by the recent cpufreq rework (Rafael Wysocki).
      
         - cpufreq core cleanups related to starting governors and frequency
           synchronization during resume from system suspend and a locking fix
           for cpufreq_quick_get() (Rafael Wysocki, Richard Cochran).
      
         - acpi-cpufreq and powernv cpufreq driver updates (Jisheng Zhang,
           Michael Neuling, Richard Cochran, Shilpasri Bhat).
      
         - intel_idle driver update preventing some Skylake-H systems from
           hanging during initialization by disabling deep C-states mishandled
           by the platform in the problematic configurations (Len Brown).
      
         - Intel Xeon Phi Processor x200 support for intel_idle
           (Dasaratharaman Chandramouli).
      
         - cpuidle menu governor updates to make it always honor PM QoS
           latency constraints (and prevent C1 from being used as the fallback
           C-state on x86 when they are set below its exit latency) and to
           restore the previous behavior to fall back to C1 if the next timer
           event is set far enough in the future that was changed in 4.4 which
           led to an energy consumption regression (Rik van Riel, Rafael
           Wysocki).
      
         - New device ID for a future AMD UART controller in the ACPI driver
           for AMD SoCs (Wang Hongcheng).
      
         - Rockchip rk3399 support for the rockchip-io-domain adaptive voltage
           scaling (AVS) driver (David Wu).
      
         - ACPI PCI resources management fix for the handling of IO space
           resources on architectures where the IO space is memory mapped
           (IA64 and ARM64) broken by the introduction of common ACPI
           resources parsing for PCI host bridges in 4.4 (Lorenzo Pieralisi).
      
         - Fix for the ACPI backend of the generic device properties API to
           make it parse non-device (data node only) children of an ACPI
           device correctly (Irina Tirdea).
      
         - Fixes for the handling of global suspend flags (introduced in 4.4)
           during hibernation and resume from it (Lukas Wunner).
      
         - Support for obtaining configuration information from Device Trees
           in the PM clocks framework (Jon Hunter).
      
         - ACPI _DSM helper code and devfreq framework cleanups (Colin Ian
           King, Geert Uytterhoeven)"

      rtc: abx80x: handle autocalibration · 59a8383a
      Mylène Josserand authored
      The autocalibration is separated in two bits to set in Oscillator
      Control register (0x1c) :
       - OSEL bit to select the oscillator type (XT or RC).
       - ACAL bit to select the autocalibration type.
      
      These functionnalities are exported in sysfs entries : "oscillator"
      and "autocalibration". Respectively, the values are "xtal" for XT
      oscillator and "rc" for RC oscillator and 0 to disable the
      autocalibration cycle, 512 for a 512 seconds autocalibration cycle
      and 1024 for a cycle of 1024 seconds.
      
      Examples :
      Set to XT Oscillator
      echo xtal > /sys/class/rtc/rtc0/device/oscillator
      Activate an autocalibration every 512 seconds
      echo 512 > /sys/class/rtc/rtc0/device/autocalibration

      Alexandre Belloni authored
      The rv8803 has a 60µs window where it will not answer on the i2c bus.
      It also means there will be no ack for the communication. Make sure
      communication is tried multiple times when this happens (the i2c subsystem
      mandates -ENXIO is that case but the number of retries is host specific).
      The critical parts are the probe function and the alarm callback so make
      sure we handle the failure there.

       - Fix a regression where bogus trip points on some Lenovo laptops start
         to screw up thermal control after commit 81ad4276 ("Thermal:
         initialize thermal zone device correctly").
      
         On these Lenovo laptops, a bogus passive trip point is reported,
         which is 0 degree Celsius.  Without commit 81ad4276, thermal zone
         fails to set cooling devices to proper cooling state, which is a bug.
         But with commit 81ad4276 applied, the processors are always
         throttled on these Lenovo laptops because the current temperature is
         always higher than the passive trip point.
      
         Fix things to ignore such bogus trip points.  (Zhang Rui)
