2014-08-01ACPI / LPSS: add LPSS device for Wildcat Point PCHJie Yang1-0/+10
INT3438 is the ADSP device on Wildcat Point platform with 2 DW DMA engines built In. The DMA engines are used for DSP FW loading and audio data transferring. These DMA engine probing need the clock, without it, probing may failed and can't go forward. Add LPSS device "INT3438" for Wildcat Point PCH, to provide clock for its ADSP DMA engine probing.

2014-07-31ACPICA: Utilities: Fix local printf issue.Lv Zheng1-0/+3
The bug can be reproduced by using a format that do not have the width.prec specified after a format that have the width.prec specified. The second formatted output will be wrong. The root cause is acpi_ut_vsnprintf() doesn't reset the specifiers to the default values. This patch fixes this issue. BZ 1094. Reported by Yizhe Wang, fixed by Lv Zheng. Since acpi_ut_vprintf() is only enabled for specific OSPM now, this patch doesn't affect Linux kernel.

2014-07-30ACPI / processor: Make it possible to get local x2apic id via _MATHanjun Guo1-0/+2
Logical processors with APIC ID values of 255 and greater are required to have a Processor Device object and must convey the processor's APIC information to OSPM using the Processor Local X2APIC structure, but not until ACPI 5.1, X2APIC structure was not supported in _MAT method. _MAT is needed for CPU hotplug and system with more than 255 CPUs will definitely need X2APIC structure, so add its support in map_mat_entry() to make it possible to get local x2apic id via _MAT based on ACPI 5.1.

2014-07-30ACPI / PNP: Fix acpi_pnp_match()Rafael J. Wysocki1-2/+1
The acpi_pnp_match() function is used for finding the ACPI device object that should be associated with the given PNP device. Unfortunately, the check used by that function is not strict enough and may cause success to be returned for a wrong ACPI device object. To fix that, use the observation that the pointer to the ACPI device object in question is already stored in the data field in struct pnp_dev, so acpi_pnp_match() can simply use that field to do its job. This problem was uncovered in 3.14 by commit 202317a573b2 (ACPI / scan: Add acpi_device objects for all device nodes in the namespace).

Temperature limit clamps are applied after converting the temperature from milli-degrees C to degrees C, so either the clamp limit needs to be specified in degrees C, not milli-degrees C, or clamping must happen before converting to degrees C. Use the latter method to avoid overflows. vrm is an u8, so the written value needs to be limited to [0, 255].

2014-07-24ACPI / PCI: Use ACPI_COMPANION() instead of ACPI_HANDLE()Rafael J. Wysocki1-9/+7
The ACPI_HANDLE() macro evaluates ACPI_COMPANION() internally to return the handle of the device's ACPI companion, so it is much more straightforward and efficient to use ACPI_COMPANION() directly to obtain the device's ACPI companion object instead of using ACPI_HANDLE() and acpi_bus_get_device() on the returned handle for the same thing. Use ACPI_COMPANION() instead of ACPI_HANDLE() in the PCI ACPI support code. Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
2014-07-24ACPI / sleep: Do not save NVS for new machines to accelerate S3Lan Tianyu1-0/+5
NVS region is saved and restored unconditionally for machines without nvs_nosave quirk during S3. Tested some new machines and the operation is not necessary. Saving NVS region also affects S2RAM speed. The time of NVS saving and restoring depends on the size of NVS region and it consumes 7~10ms normally. This patch is to make machines produced from 2012 to now not saving NVS region to accelerate S3. Signed-off-by: Lan Tianyu <tianyu.lan@intel.com> Signed-off-by: Rafael J.
