The pm2301-charger driver implements runtime pm and at the same time uses
the legacy pm callbacks for suspend and resume. This does not work since
the I2C core wont look at the legacy pm callbacks if a driver has the 'pm'
field set. This patch fixes it by moving over to dev_pm_ops for
suspend/resume as well.

This patch adds support for supplies to register a list of char *'s which
represent the list of supplies which supply them. This is the opposite as
the supplied_to list.

This change maintains support for supplied_to until all drivers which make
use of it already are converted.

The removal of __devinit and friends seems to have overlapped with the
addition of the pm2301_charger driver. Currently the driver fails to build
with the following errors:

	drivers/power/pm2301_charger.c:843:22: error: expected '=', ',', ';', 'asm' or '__attribute__' before 'pm2xxx_wall_charger_probe'
	drivers/power/pm2301_charger.c:1013:22: error: expected '=', ',', ';', 'asm' or '__attribute__' before 'pm2xxx_wall_charger_remove'
	drivers/power/pm2301_charger.c:1049:11: error: 'pm2xxx_wall_charger_probe' undeclared here (not in a function)

	drivers/power/pm2301_charger.c:1050:24: error: 'pm2xxx_wall_charger_remove' undeclared here (not in a function)

This patch removes the __dev* annotations, which fixes the build errors.

When KMS has parsed an EDID "detailed timing", it leaves the frame rate
zeroed.  Consecutive (debug-) output of that mode thus yields 0 for
vsync.  This simple fix also speeds up future invocations of
drm_mode_vrefresh().

While it is debatable whether this qualifies as a -stable fix I'd apply
it for consistency's sake; drm_helper_probe_single_connector_modes()
does the same thing already for all probed modes.

EDID spreads some values across multiple bytes; bit-fiddling is needed
to retrieve these.  The current code to parse "detailed timings" has a
cut&paste error that results in a vsync offset of at most 15 lines
instead of 63.

See

   http://en.wikipedia.org/wiki/EDID

and in the "EDID Detailed Timing Descriptor" see bytes 10+11 show why
that needs to be a left shift.

On some revisions of AT91 SoCs, the RTC IMR register is not working.
Instead of elaborating a workaround for that specific SoC or IP version,
we simply use a software variable to store the Interrupt Mask Register
and modify it for each enabling/disabling of an interrupt.  The overhead
of this is negligible anyway.

The interrupt mask register (IMR) for the RTC is broken on the AT91SAM9x5
sub-family of SoCs (good overview of the members here:
http://www.eewiki.net/display/linuxonarm/AT91SAM9x5 ).  The "user visible
effect" is the RTC doesn't work.

That sub-family is less than two years old and only has devicetree (DT)
support and came online circa lk 3.7 .  The dust is yet to settle on the
DT stuff at least for AT91 SoCs (translation: lots of stuff is still
broken, so much that it is hard to know where to start).

The fix in the patch is pretty simple: just shadow the silicon IMR
register with a variable in the driver.  Some older SoCs (pre-DT) use the
the rtc-at91rm9200 driver (e.g.  obviously the AT91RM9200) and they should
not be impacted by the change.  There shouldn't be a large volume of
interrupts associated with a RTC.

The AcpiMmioSel bit is bit 1 in the AcpiMmioEn register, but the current
sp5100_tco driver is using bit 2.

See 2.3.3 Power Management (PM) Registers page 150 of the
AMD SB800-Series Southbridges Register Reference Guide [1].

        AcpiMmioEn - RW – 8/16/32 bits - [PM_Reg: 24h]
        Field Name        Bits  Default  Description
        AcpiMMioDecodeEn  0     0b       Set to 1 to enable AcpiMMio space.
        AcpiMMIoSel       1     0b       Set AcpiMMio registers to be memory-mapped or IO-mapped space.
                                         0: Memory-mapped space
                                         1: I/O-mapped space

The sp5100_tco driver expects zero as a value of AcpiMmioSel (bit 1).

Fortunately, no problems were caused by this typo, because the default
value of the undocumented misused bit 2 seems to be zero.

However, the sp5100_tco driver should use the correct bitmask value.
