2011-03-28intel_mid_powerbtn: add power button driver for Medfield platform (#3)Hong Liu
The power button is connected to MSIC on Medfield, we will get two interrupts from IOAPIC when pressing or releasing the power button.

2011-03-28asus-laptop: remove deprecated interfaces (lcd_switch and display_get)Corentin Chary
I should have done that one year ago, so it's more than time to do it. These two features use non-standard interfaces. There are the only features that really need multiple path to guess what's the right method name on a specific laptop. Removing them allow to remove a lot of code an significantly clean the driver. This will affect the backlight code which won't be able to know if the backlight is on or off. The platform display file will also be write only (like the one in eeepc-laptop).

2011-03-28eeepc-wmi: serialize access to wmi methodCorentin Chary
\AMW0.WMBC, which is the main method that we use, is not reentrant. When wireless hotpluging is enabled, toggling the status of the wireless device using WMBC will trigger a notification and the notification handler need to call WMBC again to get the new status of the device, this will trigger the following error: ACPI Error (dswload-0802): [_T_0] Namespace lookup failure, AE_ALREADY_EXISTS ACPI Exception: AE_ALREADY_EXISTS, During name lookup/catalog (20100428/psloop-231) ACPI Error (psparse-0537): Method parse/execution failed [\AMW0.WMBC] (Node f7023b88), AE_ALREADY_EXISTS ACPI: Marking method WMBC as Serialized because of AE_ALREADY_EXISTS error Since there is currently no way to tell the acpi subsystem to mark a method as serialized, we do it in eeepc-wmi. Of course, we could let the first call fail, and then it would work, but it doesn't seems really clean, and it will make the first WMBC call return a random value. This patch was tested on EeePc 1000H with a RaLink RT2860 wireless card using the rt2800pci driver. rt2860sta driver seems to deadlock when we remove the pci device...

2011-03-28eeepc-wmi: add hotplug code for Eeepc 1000HCorentin Chary
Implement wireless like hotplug handling (code stolen from eeepc-laptop). Reminder: on some models rfkill is implemented by logically unplugging the wireless card from the PCI bus. Despite sending ACPI notifications, this does not appear to be implemented using standard ACPI hotplug - nor does the firmware provide the _OSC method required to support native PCIe hotplug. The only sensible choice appears to be to handle the hotplugging directly in the platform driver. Signed-off-by: Corentin Chary <corentincj@iksaif.net> Signed-off-by: Matthew Garrett <mjg@redhat.com>

2011-03-27mfd: twl4030: Cleanup interrupt handlingThomas Gleixner
irq_desc checking in a function which is called with that irq descriptor locked, is pointless. Equally pointless as the irq desc check in the interrupt service routine. The driver sets those lines up, so that cant go away magically. Remove the open coded handler magic and use the proper accessor. No need to fiddle with irq_desc in the type setting function. The original value is in irq_data and the core code stores the new setting when the return value is 0. This driver needs to be converted to threaded interrupts and buslock.

2011-03-27mfd: Add MAX8997/8966 IRQ controlMyungJoo Ham
This patch enables IRQ handling for MAX8997/8966 chips. Please note that Fuel-Gauge-related IRQs are not implemented in this initial release. The fuel gauge module in MAX8997 is identical to MAX17042, which is already in Linux kernel. In order to use the already-existing MAX17042 driver for fuel gauge module in MAX8997, the main interrupt handler of MAX8997 should relay related interrupts to MAX17042 driver. However, in order to do this, we need to modify MAX17042 driver as well because MAX17042 driver does not have any interrupt handlers for now. We are not going to implement this in this initial release as it is not crucial in basic operations of MAX8997.

The cs5535-pms cell doesn't actually need to be cloned, so we can drop that and simply have the olpc-xo1.c driver use "cs5535-pms" directly. Also, rename the cs5535-acpi clones to what we actually use for the (currently out-of-tree) SCI driver.

2011-03-27mfd: Add mfd_clone_cell(), convert cs5535-mfd/olpc-xo1 to itAndres Salomon
Replace mfd_shared_platform_driver_register with mfd_clone_cell. The former was called by an mfd client, and registered both a platform driver and device. The latter is called by an mfd driver, and registers only a platform device. The downside of this is that mfd drivers need to be modified whenever new clients are added that share a cell; the upside is that it fits Linux's driver model better. It's also simpler. This also converts cs5535-mfd/olpc-xo1 from the old API. cs5535-mfd now creates the olpc-xo1-{acpi,pms} devices, while olpc-xo1 binds to them via platform drivers.
