In order to get exact 24MHz clock frequency value for the camera
sensor and avoid rounding errors the parent clock must be CLK_XUSBXTI,
not CLK_MOUT_MPLL_USER_T. Currently the sensor's master clock
frequency is too high and the sensor doesn't work properly.
This fixes commit 0357a4438d531ef3cf529e80ffcd208eb8e35f55

Remove fixed regulators (duplicating what max77686 provides) and
add GPIO enable control to max77686 regulators.
This gives the system full control over those regulators. Previously
the state of such regulators was a mixture of what max77686 driver set
over I2C and what regulator-fixed set through GPIO.
Removal of 'regulator-always-on' from CAM_ISP_CORE_1.2V (buck9) allows
disabling it when it is not used. Previously this regulator was always
enabled because its enable state is a OR of:
- ENB9 GPIO (turned always on by regulator-fixed),
- BUCK9EN field in BUCK9CTRL register (off by max77686 through I2C).

approximately from 17 mA to 9 mA.

Add node for fuel gauge present in Maxim 77693 PMIC. This allows control
over battery charging state on Trats2 board.
The fuel gauge is compatible with max17042 battery driver (Maxim
17042/17047/17050). Although datasheet rev 2.2 for MAX77693 describes
fuel gauge as Maxim 17042-like, the chip on Trats2 board identifies
itself as Maxim 17047-like.

The DISP1 power domain on Exynos5420 SoC includes the FIMD1, MIXER
and HDMI modules. Add a device node for this power domain and mark
these modules as consumer of the DISP1 power domain.
When a power domain is powered on and off, the input clocks of the
devices attached to it are reparented. So a reference to the input
and parent clocks of the devices are needed to manage that.

There is one sensor for each of these power rails:
- A15 cluster: VDD_ARM
- A7 cluster: VDD_KFC
- GPU: VDD_G3D
- memory: VDD_MEM
In addition to adding the sensors, LDO26 from the PMIC needs to be
enabled because it's powering these sensor.

so the SoC I/O pins have to be configured in external interrupt

lines but is better to set it explicitly instead of relying on

Pull ACCESS_ONCE cleanup preparation from Christian Borntraeger:
"kernel: Provide READ_ONCE and ASSIGN_ONCE
As discussed on LKML http://marc.info/?i=54611D86.4040306%40de.ibm.com
ACCESS_ONCE might fail with specific compilers for non-scalar
accesses.
Here is a set of patches to tackle that problem.
The first patch introduce READ_ONCE and ASSIGN_ONCE. If the data
structure is larger than the machine word size memcpy is used and a
warning is emitted. The next patches fix up several in-tree users of
ACCESS_ONCE on non-scalar types.
This does not yet contain a patch that forces ACCESS_ONCE to work only
on scalar types. This is targetted for the next merge window as Linux
next already contains new offenders regarding ACCESS_ONCE vs.
non-scalar types"

strcmp was lost when all other string functions were removed,

so any driver built as a module would not have access to this symbol.
In a similar manner, we had optimized versions of
csum_partial_copy_from_user and __do_clear_user
but no exported symbols for them, breaking bunch of other drivers
when built as a module.
At the same time, move EXPORT_SYMBOL(__copy_user) and
