| * PCI/PM: Report wakeup events before resuming devicesRafael J. Wysocki2011-01-14
| | | | | | | | | | | | | | | | | | Make wakeup events be reported by the PCI subsystem before attempting to resume devices or queuing up runtime resume requests for them, because wakeup events should be reported as soon as they have been detected.

| * PCI/PM: Use pm_wakeup_event() directly for reporting wakeup eventsRafael J. Wysocki2011-01-14
| | | | | | | | | | | | | | | | | | | | After recent changes related to wakeup events pm_wakeup_event() automatically checks if the given device is configured to signal wakeup, so pci_wakeup_event() may be a static inline function calling pm_wakeup_event() directly.

| * PCI: sysfs: Update ROM to include default owner write accessAlex Williamson2011-01-14
| | | | | | | | | | | | | | | | | | | | | | | | The PCI sysfs ROM interface requires an enabling write to access the ROM image, but the default file mode is 0400. The original proposed patch adding sysfs ROM support was a true read-only interface, with the enabling bit coming in as a feature request. I suspect it was simply an oversight that the file mode didn't get updated to match the API.

| * PCI/ACPI: Request _OSC control once for each root bridge (v3)Rafael J. Wysocki2011-01-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Move the evaluation of acpi_pci_osc_control_set() (to request control of PCI Express native features) into acpi_pci_root_add() to avoid calling it many times for the same root complex with the same arguments. Additionally, check if all of the requisite _OSC support bits are set before calling acpi_pci_osc_control_set() for a given root complex.

| * PCI/PCIe: Clear Root PME Status bits early during system resumeRafael J. Wysocki2010-12-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I noticed that PCI Express PMEs don't work on my Toshiba Portege R500 after the system has been woken up from a sleep state by a PME (through Wake-on-LAN). After some investigation it turned out that the BIOS didn't clear the Root PME Status bit in the root port that received the wakeup PME and since the Requester ID was also set in the port's Root Status register, any subsequent PMEs didn't trigger interrupts. This problem can be avoided by clearing the Root PME Status bits in all PCI Express root ports during early resume. For this purpose, add an early resume routine to the PCIe port driver and make this driver be always registered, even if pci_ports_disable is set (in which case the driver's only function is to provide the early resume callback).

| * PCI: pci-stub: ignore zero-length id parametersTejun Heo2010-12-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | pci-stub uses strsep() to separate list of ids and generates a warning message when it fails to parse an id. However, not specifying the parameter results in ids set to an empty string. strsep() happily returns the empty string as the first token and thus triggers the warning message spuriously. Make the tokner ignore zero length ids.

Also, a large majority of the callers do not check the return code of pci_restore_state. Make the pci_restore_state a void return and avoid the overhead.

| * PCI: Disable ASPM if BIOS asks us toMatthew Garrett2010-12-23
| | | | | | | | | | | | | | | | | | | | | | | | | | We currently refuse to touch the ASPM registers if the BIOS tells us that ASPM isn't supported. This can cause problems if the BIOS has (for any reason) enabled ASPM on some devices anyway. Change the code such that we explicitly clear ASPM if the FADT indicates that ASPM isn't supported, and make sure we tidy up appropriately on device removal in order to deal with the hotplug case. If ASPM is disabled because the BIOS doesn't hand over control then we won't touch the registers.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The MAX17042 is a fuel gauge with an I2C interface for lithium-ion betteries. Unlike its predecessor MAX17040, MAX17042 uses 16bit registers. Besides, MAX17042 has much more features than MAX17040; e.g., a thermistor, current and current accumulation measurement, battery internal resistance estimate, average values of measurement, and others. This patch implements a driver for MAX17042. In this initial release, we have implemented the most basic features of a fuel gauge: measure the battery capacity and voltage.

| * | | mfd: Support LP3974 RTCMyungJoo Ham2011-01-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The first releases of LP3974 have a large delay in RTC registers, which requires 2 seconds of delay after writing to a rtc register (recommended by National Semiconductor's engineers) before reading it. If "rtc_delay" field of the platform data is true, the rtc driver assumes that such delays are required. Although we have not seen LP3974s without requiring such delays, we assume that such LP3974s will be released soon (or they have done so already) and they are supported by "lp3974" without setting "rtc_delay" at the platform data. This patch adds delays with msleep when writing values to RTC registers if the platform data has rtc_delay set.

| * | | i2c: Convert SCx200 driver from using raw PCI to platform deviceAndres Salomon2011-01-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The SCx200 ACB driver supports ISA hardware as well as PCI. The PCI hardware is CS5535/CS5536 based, and the device that it grabs is handled by the cs5535-mfd driver. This converts the SCx200 driver to use a platform_driver rather than the previous PCI hackery. The driver used to manually track the iface list (via linked list); now it only does this for ISA devices. PCI ifaces are handled through standard driver model lists. It's unclear what happens in case of errors in the old ISA code; rather than pretending the code actually cares, I've dropped the (implicit) ignorance of return values and marked it with a comment.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While it is vanishingly unlikely that the device will be deployed on other architectures removing the dependency facilitates build testing when doing generic work on both the MFD core for the device and the subsystem drivers.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since we don't have a PWM API every PWM driver ends up exporting its own version and we need to limit the platforms we try to build them on in order to avoid multiple definitions. As the AB8500 is normally a companion chip for the U8500 CPU depend on that architecture.
