Some versions of tps65218 do not seem to support poweroff modes properly
if DCDC3 regulator is shut-down. Thus, keep it enabled even during
poweroff if the version info matches the broken silicon revision.

The reset value for this register seems broken on certain versions of
tps65218 chip, so make sure the dcdc3 settings is proper. Needed for
proper functionality of rtc+ddr / rtc-only modes.

TPS65218 has a pre-defined power-up / power-down sequence which in
a typical application does not need to be changed. However, it is possible
to define custom sequences under I2C control. The power-up sequence is
defined by strobes and delay times. Each output rail is assigned to a
strobe to determine the order in which the rails are enabled.
Every regulator has sequence registers and every regulator has a default
strobe value and gets disabled when a particular power down sequence
occurs.
To keep a regulator on during suspend we write value 0 to strobe so
that the regulator is out of all sequencers and is not impacted by any
power down sequence. Hence saving the default strobe value during probe
so that when we want to regulator to be enabled during suspend we write 0
to strobe and when we want it to get disabled during suspend we write
the default saved strobe value.
This allows platform data to specify which power rails should be on or off
during RTC only suspend. This is necessary to keep DDR state while in RTC
only suspend.

Here's the set of driver core patches for 3.19-rc1.
They are dominated by the removal of the .owner field in platform
drivers. They touch a lot of files, but they are "simple" changes, just
removing a line in a structure.
Other than that, a few minor driver core and debugfs changes. There are
some ath9k patches coming in through this tree that have been acked by
the wireless maintainers as they relied on the debugfs changes.
Everything has been in linux-next for a while.

The of_get_regulator_init_data() function is used to extract the regulator
init_data but information on how to extract certain data is defined in the
static regulator descriptor (e.g: how to map the hardware operating modes).
Add a const struct regulator_desc * parameter to the function signature so
the parsing logic could use the information in the struct regulator_desc.
of_get_regulator_init_data() relies on of_get_regulation_constraints() to
actually extract the init_data so it has to pass the struct regulator_desc
but that is modified on a later patch.
