Remove the pointless irq_desc check in set_type. This function is
called with that irq descriptor locked. Also remove the write back of
the flow type as the core code does this already when the return value
is 0.

Also store the flow type in the chip data structure, so there is no
need to fiddle in the irq descriptor.

Replace the open coded handler call with the prober accessor. Retrieve
the handler data from desc. That avoids a redundant lookup in the

There is no point in checking irq_desc here, as it _is_ available. The
driver configured those lines, so they cannot go away.

The home brewn disabled/note_interrupt magic can be removed as well by
adding a irq_disable callback which avoids the lazy disable.

That driver needs to be converted to threaded interrupts.

The TPS61050/61052 driver uses MFD core code, yet does not specify the
dependency in Kconfig. If it is the only MFD driver configured, compilation
fails with

ERROR: "mfd_add_devices" [drivers/mfd/tps6105x.ko] undefined!
ERROR: "mfd_remove_devices" [drivers/mfd/tps6105x.ko] undefined!

Fix the problem by adding "select MFD_CORE" to the respective Kconfig entry.

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.  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.

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.
