2011-01-14PCI/PM: Use pm_wakeup_event() directly for reporting wakeup eventsRafael J. Wysocki
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.

2011-01-14PCI: sysfs: Update ROM to include default owner write accessAlex Williamson
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.

2011-01-14PCI/ACPI: Request _OSC control once for each root bridge (v3)Rafael J. Wysocki
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.

Commit a1f5f22adc3206c47e70652c12671666c65b579f ("gpio: timbgpio: irq_data conversion") was slightly too enthusiastic in converting timbgpio_irq() over to take an irq_data * argument instead of an unsigned int irq argument, as it is a flow handler, which still take IRQ numbers for now. (And on top of that, it was using the wrong accessors.) This fixes it up, and seems to build without warnings.

2011-01-14[SCSI] sd,sr: kill compat SDEV_MEDIA_CHANGE eventTejun Heo
SDEV_MEDIA_CHANGE event was first added by commit a341cd0f (SCSI: add asynchronous event notification API) for SATA AN support and then extended to cover generic media change events by commit 285e9670 ([SCSI] sr,sd: send media state change modification events). This event was mapped to block device in userland with all properties stripped to simulate CHANGE event on the block device, which, in turn, was used to trigger further userspace action on media change. The recent addition of disk event framework kept this event for backward compatibility but it turns out to be unnecessary and causes erratic and inefficient behavior. The new disk event generates proper events on the block devices and the compat events are mapped to block device with all properties stripped, so the block device ends up generating multiple duplicate events for single actual event. This patch removes the compat event generation from both sr and sd as suggested by Kay Sievers. Both existing and newer versions of udev and the associated tools will behave better with the removal of these events as they from the beginning were expecting events on the block devices.

2011-01-14[SCSI] sd: implement sd_check_events()Tejun Heo
Replace sd_media_change() with sd_check_events(). * Move media removed logic into set_media_not_present() and media_not_present() and set sdev->changed iff an existing media is removed or the device indicates UNIT_ATTENTION. * Make sd_check_events() sets sdev->changed if previously missing media becomes present. * Event is reported only if sdev->changed is set. This makes media presence event reported if scsi_disk->media_present actually changed or the device indicated UNIT_ATTENTION. For backward compatibility, SDEV_EVT_MEDIA_CHANGE is generated each time sd_check_events() detects media change event.

2011-01-14power_supply: Add MAX17042 Fuel Gauge DriverMyungJoo Ham
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.

2011-01-14mfd: Support LP3974 RTCMyungJoo Ham
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.

2011-01-14i2c: Convert SCx200 driver from using raw PCI to platform deviceAndres Salomon
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.
