2010-05-28ACPI: Don't let acpi_pad needlessly mark TSC unstableVenkatesh Pallipadi1-2/+11
acpi pad driver kind of aggressively marks TSC as unstable at init time, on mwait capable and non X86_FEATURE_NONSTOP_TSC systems. This is irrespective of whether pad driver is ever going to be used on the system or deep C-states are supported/used. This will affect every user who just happens to compile in (or get a kernel version which compiles in) acpi pad driver. Move mark_tsc_unstable() out of init to the actual idle invocation path of the pad driver. There is also another bug/missing_feature in the code that it does not support 'always running apic timer' and switches to broadcast mode unconditionally. Shaohua, can you take a look at that please.

acpi_enter_[simple,bm] does idle timing in ns, convert it to timeval, then to us, then to pmtimer_ticks and then back to ns. This patch changes things to idle timing in ns, convert it to us, and then to pmtimer_ticks. Just saves an imul along this path, but makes the code cleaner.

2010-05-28intel_idle: native hardware cpuidle driver for latest Intel processorsLen Brown5-2/+479
This EXPERIMENTAL driver supersedes acpi_idle on Intel Atom Processors, Intel Core i3/i5/i7 Processors and associated Intel Xeon processors. It does not support the Intel Core2 processor or earlier. For kernels configured with ACPI, CONFIG_INTEL_IDLE=y allows intel_idle to probe before the ACPI processor driver. Booting with "intel_idle.max_cstate=0" disables intel_idle and the system will fall back on ACPI's "acpi_idle". Typical Linux distributions load ACPI processor module early, making CONFIG_INTEL_IDLE=m not easily useful on ACPI platforms. intel_idle probes all processors at module_init time. Processors that are hot-added later will be limited to using C1 in idle. Signed-off-by: Len Brown <len.brown@intel.com>
2010-05-28ACPI: acpi_idle: touch TS_POLLING only in the non-MWAIT caseLen Brown1-12/+16
commit d306ebc28649b89877a22158fe0076f06cc46f60 (ACPI: Be in TS_POLLING state during mwait based C-state entry) fixed an important power & performance issue where ACPI c2 and c3 C-states were clearing TS_POLLING even when using MWAIT (ACPI_STATE_FFH). That bug had been causing us to receive redundant scheduling interrups when we had already been woken up by MONITOR/MWAIT. Following up on that... In the MWAIT case, we don't have to subsequently check need_resched(), as that c heck was there for the TS_POLLING-clearing case. Note that not only does the cpuidle calling function already check need_resched() before calling us, the low-level entry into monitor/mwait calls it twice -- guaranteeing that a write to the trigger address can not go un-noticed. Also, in this case, we don't have to set TS_POLLING when we wake, because we never cleared it. Signed-off-by: Len Brown <len.brown@intel.com> Acked-by: Venkatesh Pallipadi <venki@google.com>

2010-05-27ACPI: allow a native cpuidle driver to displace ACPILen Brown1-5/+6
The ACPI driver would fail probe when it found that another driver had previously registered with cpuidle. But this is a natural situation, as a native hardware cpuidle driver should be able to bind instead of ACPI, and the ACPI processor driver should be able to handle yielding control of C-states while still handling P-states and T-states. Add a KERN_DEBUG line showing when acpi_idle does successfully register. Signed-off-by: Len Brown <len.brown@intel.com>

The rdc321x southbridge PCI device has no MEM PCI resources that we could pass to mfd_add_devices. Since 33254dd5, mfd_add_device checks for the mem_base argument that we set to NULL. Changing the resources passed to our MFD cells from IORESOURCE_MEM to IORESOURCE_IO fixes that. Since we use those resources as offsets to the PCI configuration space base address of the southbridge device this is also more adequate.

2010-05-28mfd: AB3550 core driverMattias Wallin3-0/+1416
This adds a core driver for the AB3550 mixed-signal circuit found in the ST-Ericsson U300 platforms. This driver is a singleton proxy for all access to the AB3550 sub functionality drivers which can be added on top of this one: RTC, regulators, battery and system power control, vibrator, LEDs and an ALSA codec.

2010-05-28mfd: AB3100 register access change to abx500 APIMattias Wallin7-77/+271
The interface for the AB3100 is changed to make way for the ABX500 family of chips: AB3550, AB5500 and future ST-Ericsson Analog Baseband chips. The register access functions are moved out to a separate struct abx500_ops. In this way the interface is moved from the implementation and the sub functionality drivers can keep their interface intact when chip infrastructure and communication mechanisms changes. We also define the AB3550 device IDs and the AB3550 platform data struct and convert the catenated 32bit event to an array of 3 x 8bits.
