- Rework of the core ACPI resources parsing code to fix issues
    in it and make using resource offsets more convenient and
    consolidation of some resource-handing code in a couple of places
    that have grown analagous data structures and code to cover the
    the same gap in the core (Jiang Liu, Thomas Gleixner, Lv Zheng).
 
  - ACPI-based IOAPIC hotplug support on top of the resources handling
    rework (Jiang Liu, Yinghai Lu).

    handling rework that allows drivers to install raw handlers for
    ACPI GPEs which then become entirely responsible for the given GPE
    and the ACPICA core code won't touch it (Lv Zheng, David E Box,
    Octavian Purdila).
 
  - ACPI EC driver rework to fix several concurrency issues and other
    problems related to events handling on top of the ACPICA's new
    support for raw GPE handlers (Lv Zheng).

    Subsystem) driver for Intel chips (Ken Xue).

  - Rework of the ACPI processor driver's handling of idle states
    to make the code more straightforward and less bloated overall
    (Rafael J Wysocki).
 
  - Assorted minor fixes related to ACPI and SFI (Andreas Ruprecht,
    Andy Shevchenko, Hanjun Guo, Jan Beulich, Rafael J Wysocki,

Pull ACPI and power management updates from Rafael Wysocki:
 "We have a few new features this time, including a new SFI-based
  cpufreq driver, a new devfreq driver for Tegra Activity Monitor, a new
  devfreq class for providing its governors with raw utilization data
  and a new ACPI driver for AMD SoCs.

  Still, the majority of changes here are reworks of existing code to
  make it more straightforward or to prepare it for implementing new
  features on top of it.  The primary example is the rework of ACPI
  resources handling from Jiang Liu, Thomas Gleixner and Lv Zheng with
  support for IOAPIC hotplug implemented on top of it, but there is
  quite a number of changes of this kind in the cpufreq core, ACPICA,
  ACPI EC driver, ACPI processor driver and the generic power domains
  core code too.

  The most active developer is Viresh Kumar with his cpufreq changes.

  Specifics:

* Samsung Exynos PPMU (Platform Performance Monitoring Unit) device
The Samsung Exynos SoC has PPMU (Platform Performance Monitoring Unit) for
each IP. PPMU provides the primitive values to get performance data. These
PPMU events provide information of the SoC's behaviors so that you may
use to analyze system performance, to make behaviors visible and to count
usages of each IP (DMC, CPU, RIGHTBUS, LEFTBUS, CAM interface, LCD, G3D, MFC).
The Exynos PPMU driver uses the devfreq-event class to provide event data
to various devfreq devices. The devfreq devices would use the event data when
derterming the current state of each IP.
Required properties:
- compatible: Should be "samsung,exynos-ppmu".
- reg: physical base address of each PPMU and length of memory mapped region.
Optional properties:
- clock-names : the name of clock used by the PPMU, "ppmu"
- clocks : phandles for clock specified in "clock-names" property
- #clock-cells: should be 1.
Example1 : PPMU nodes in exynos3250.dtsi are listed below.
ppmu_dmc0: ppmu_dmc0@106a0000 {
compatible = "samsung,exynos-ppmu";
reg = <0x106a0000 0x2000>;
status = "disabled";
};
ppmu_dmc1: ppmu_dmc1@106b0000 {
compatible = "samsung,exynos-ppmu";
reg = <0x106b0000 0x2000>;
status = "disabled";
};
ppmu_cpu: ppmu_cpu@106c0000 {
compatible = "samsung,exynos-ppmu";
reg = <0x106c0000 0x2000>;
status = "disabled";
};
ppmu_rightbus: ppmu_rightbus@112a0000 {
compatible = "samsung,exynos-ppmu";
reg = <0x112a0000 0x2000>;
clocks = <&cmu CLK_PPMURIGHT>;
clock-names = "ppmu";

reg = <0x116a0000 0x2000>;
clocks = <&cmu CLK_PPMULEFT>;
clock-names = "ppmu";
status = "disabled";
};
Example2 : Events of each PPMU node in exynos3250-rinato.dts are listed below.
&ppmu_dmc0 {
status = "okay";
events {
ppmu_dmc0_3: ppmu-event3-dmc0 {

@ -69,6 +69,10 @@ Reason for this is that the RTC is the only reliably available piece of
hardware during resume operations where a value can be set that will
survive a reboot.
pm_trace is not compatible with asynchronous suspend, so it turns
asynchronous suspend off (which may work around timing or
ordering-sensitive bugs).
Consequence is that after a resume (even if it is successful) your system
clock will have a value corresponding to the magic number instead of the
correct date/time! It is therefore advisable to use a program like ntp-date

* Note: If a GPE is shared by 2 silicon components, then both the drivers
