2011-04-12mfd: Fetch cell pointer from platform_device->mfd_cellSamuel Ortiz1-2/+14
In order for MFD drivers to fetch their cell pointer but also their platform data one, an mfd cell pointer is added to the platform_device structure. That allows all MFD sub devices drivers to be MFD agnostic, unless they really need to access their MFD cell data. Most of them don't, especially the ones for IPs used by both MFD and non MFD SoCs.

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.

2011-03-27mfd: Add MAX8997/8966 IRQ controlMyungJoo Ham2-1/+378
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.

2011-03-27mfd: OLPC: Clean up names to match what OLPC actually usesDaniel Drake1-3/+1
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. In the process, that fixes a subtle bug in olpc-xo1.c which broke powerdown on XO-1s.. olpc-xo1-ac-acpi was a typo, not something that actually existed.

2011-03-27mfd: Add mfd_clone_cell(), convert cs5535-mfd/olpc-xo1 to itAndres Salomon2-42/+29
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.

On sh-mobile platforms the SDHI driver was using the tmio_mmc SD/SDIO MFD cell driver. Now that the tmio_mmc driver has been split into a core and a separate MFD glue, we can support SDHI natively without the need to emulate an MFD controller. This also allows to support systems with an on-SoC SDHI controller and a separate MFD with a TMIO core.

This makes it possible to have multiple AB8500 GPADC instances instead of it being a singleton, and rids the need to keep a GPADC pointer around in the core AB8500 MFD struct. Currently the match is made to the device name which is by default numbered from the device instance such as "ab8500-gpadc.0" but by using the .init_name field of the device a more intiutive naming for the GPADC blocks can be achieved if desired.
