mfd: ab8500-core: Use 'ifdef' for config options

2014-08-20T12:28:02+00:00

The config symbol 'CONFIG_DEBUG_FS' should be protected by a 'ifdef' instead
of a plain 'if'.

mfd: ab8500-core: Remove pointless else in if statement

2014-07-09T15:37:27+00:00

Save a line of code (albeit, it's replaced by a blank line, but
still), as the else is superfluous.

mfd: ab8500: Fix dt irq mapping

2014-06-26T12:34:15+00:00

The AD8500 defines itself as interrupt-controller in DT,
but it doesn't assign DT node to IRQ domain when creates it.
As result, of_irq_xx() helpers don't work because they can't
find necessary IRQ domain.

Hence, fix it by assigning AD8500 core device DT node to IRQ
domain when it's created.

mfd: dbx500/abx500: root out hardcoded IRQ assignments

2014-03-04T00:58:11+00:00

The DBx500 and ABx500 should be getting their IRQs from the
device tree and nowhere else. Get rid of all the static assignments
everywhere, delete it from the driver, platform data and the
board files in one swift strike.

Lots of cross-dependencies in the MFD drivers for PRCMU and
AB8500 makes it necessary to strike everywhere at once to
eradicate IRQs passed as resources and platform data to the left
and right around the platform.

mfd: ab8500: Use irqdomain to map interrupts

2014-01-21T08:27:49+00:00

All subdrivers use the irqdomain to demux AB8500 IRQs but here
in the hierarchical path we find a leftover instance using the
hard-coded IRQ base. Convert it to use irqdomain with a
oneliner.

mfd: Constify struct mfd_cell where possible

2014-01-06T09:13:29+00:00

As of commit 03e361b25ee8dfb1fd9b890072c23c4aae01c6c7 ("mfd: Stop setting
refcounting pointers in original mfd_cell arrays"), the "cell" parameter of
mfd_add_devices() is "const" again. Hence make all cell data passed to
mfd_add_devices() const where possible.

mfd: ab8500-core: Add AB8500 external regulators as MFD devices

2013-06-13T09:52:00+00:00

The AB8500 external regulator driver is now a device in its own right,
so it requires registering and probing in the normal way. This patch
will ensure the driver is probed once registered for all devices which
support them.
