Linus Torvalds cd50b70ccd Additional power management and ACPI updates for v3.20-rc1
- Revert a recent ACPI LPSS driver commit that prevented the touchpad
    driver from loading on Dell XPS13 (Jarkko Nikula).
 
  - Make the ACPI LPSS driver disable the I2C controllers and deassert
    SPI host controllers resets at startup on Intel BayTrail and Braswell
    SoCs in case they have been left in wrong states by the platform
    firmware which then may casuse fatal controller driver failures during
    resume from hibernation (Mika Westerberg).
 
  - Make two recently added ACPI EC messages look better (Scot Doyle).
 
  - Reduce the printk level of a recently added debug message related to
    ACPI resources that may become noisy in some cases (Rafael J Wysocki).
 
  - Add a new ACPI backlight blacklist entry for Samsung Series 9
    (900X3C/900X3D/900X3E/900X4C/900X4D) laptops where the native backlight
    interface doesn't work while the ACPI based one does (Jens Reyer).
 
  - Make the PNP sybsystem's core code use __request_region() followed by
    __release_region() instead of __check_region() which then will allow
    us to get rid of the latter as it has no more users (Jakub Sitnicki).
 
  - Fix a build breakage and an issue with two __init functions that may be
    called after initialization in the s3c cpufreq driver (Arnd Bergmann).
 
  - Make the powernv cpuidle driver read target_residency values for idle
    states from a Device Tree (as we have the suitable DT bindings for that
    now) and improve the parsing of the powermgmt DT node in that driver
    (Preeti U Murthy).

Merge tag 'pm+acpi-3.20-rc1-3' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull one more batch of power management and ACPI updates from Rafael Wysocki:
 "These are mostly fixes on top of the previously merged recent PM and
  ACPI material.

  First, one commit that broke the ACPI LPSS (Low-Power Subsystem)
  driver on a Dell box is reverted and there are two stable-candidate
  fixes for that driver.  Another fix cleans up two recently added ACPI
  EC messages that look odd and the printk level of a noisy debug
  message in the core ACPI resources handling code is reduced.

  In addition to that we have two stable-candidate fixes for the s3c
  cpufreq driver, two cpuidle powernv driver updates related to Device
  Trees and a PNP subsystem cleanup that will allow us to get rid of
  some old ugliness going forward.  Also there is a new blacklist entry
  for the ACPI backlight code.

  Specifics:

   - Revert a recent ACPI LPSS driver commit that prevented the touchpad
     driver from loading on Dell XPS13 (Jarkko Nikula).

   - Make the ACPI LPSS driver disable the I2C controllers and deassert
     SPI host controllers resets at startup on Intel BayTrail and
     Braswell SoCs in case they have been left in wrong states by the
     platform firmware which then may casuse fatal controller driver
     failures during resume from hibernation (Mika Westerberg).

   - Make two recently added ACPI EC messages look better (Scot Doyle).

   - Reduce the printk level of a recently added debug message related
     to ACPI resources that may become noisy in some cases (Rafael J
     Wysocki).

   - Add a new ACPI backlight blacklist entry for Samsung Series 9
     (900X3C/900X3D/900X3E/900X4C/900X4D) laptops where the native
     backlight interface doesn't work while the ACPI based one does
     (Jens Reyer).

   - Make the PNP sybsystem's core code use __request_region() followed
     by __release_region() instead of __check_region() which then will
     allow us to get rid of the latter as it has no more users (Jakub
     Sitnicki).

   - Fix a build breakage and an issue with two __init functions that
     may be called after initialization in the s3c cpufreq driver (Arnd
     Bergmann).

   - Make the powernv cpuidle driver read target_residency values for
     idle states from a Device Tree (as we have the suitable DT bindings
     for that now) and improve the parsing of the powermgmt DT node in
     that driver (Preeti U Murthy)"
