2011-01-10platform/x86: Consistently select LEDS Kconfig optionsMark Brown
Currently the x86 platform devices are not consistent about selecting or depending on the LEDs Kconfig variables, and this inconsistency leads to Kconfig getting upset and refusing to offer LEDs (even on non-x86 platforms): drivers/platform/x86/Kconfig:422:error: recursive dependency detected! drivers/platform/x86/Kconfig:422: symbol EEEPC_WMI depends on ACPI_WMI drivers/platform/x86/Kconfig:438: symbol ACPI_WMI is selected by ACER_WMI drivers/platform/x86/Kconfig:18: symbol ACER_WMI depends on LEDS_CLASS drivers/leds/Kconfig:10: symbol LEDS_CLASS is selected by EEEPC_WMI Fix this by always selecting rather than depending on the symbols as slightly more drivers use this approach already and it seems more user friendly.

We don't need to call bios/acpi (cmpc_set_rfkill_wlan) if the blocked state is already set to the same value (little optimization). This can happen for example if we initialize the module with same initial hardware state (rfkill core always call cmpc_rfkill_block on initialization here). Also GWRI method only accepts 0 or 1 for setting rfkill block, as can be seen on AML code from acpidump->DSDT from a classmate sample I have, so should be fine setting state only to 0 or 1 directly.

WMI data blocks can contain WMI events with the same GUID but with different notifiy_ids, for example volume up/down hotkeys. This patch enables a single event handler to be registered and unregistered against all events with same GUID but different notify_ids. Since an event handler is passed the notify_id of an event it can can differentiate between the different events. The patch also ensures we only register and unregister a device per unique GUID.

2010-12-23drm/i915, intel_ips: When i915 loads after IPS, make IPS relink to i915.Eric Anholt
The IPS driver is designed to be able to run detached from i915 and just not enable GPU turbo in that case, in order to avoid module dependencies between the two drivers. This means that we don't know what the load order between the two is going to be, and we had previously only supported IPS after (optionally) i915, but not i915 after IPS. If the wrong order was chosen, you'd get no GPU turbo, and something like half the possible graphics performance.

2010-11-09x86/mrst: Add SFI platform device parsing codeFeng Tang
SFI provides a series of tables. These describe the platform devices present including SPI and I²C devices, as well as various sensors, keypads and other glue as well as interfaces provided via the SCU IPC mechanism (intel_scu_ipc.c) This patch is a merge of the core elements and relevant fixes from the Intel development code by Feng, Alek, myself into a single coherent patch for upstream submission. It provides the needed infrastructure to register I2C, SPI and platform devices described by the tables, as well as handlers for some of the hardware already supported in kernel. The 0.8 firmware also provides GPIO tables. Devices are created at boot time or if they are SCU dependant at the point an SCU is discovered. The existing Linux device mechanisms will then handle the device binding. At an abstract level this is an SFI to Linux device translator. Device/platform specific setup/glue is in this file. This is done so that the drivers for the generic I²C and SPI bus devices remain cross platform as they should.
