Third set of IIO fixes for the 3.18 cycle.
Most of these are fairly standard little fixes, a bmc150 and bmg160 patch
is to make an ABI change to indicated a specific axis in an event rather
than the generic option in the original drivers. As both of these drivers
are new in this cycle it would be ideal to push this minor change through
even though it isn't strictly a fix. A couple of other 'fixes' change
defaults for some settings on these new drivers to more intuitive calues.
Looks like some useful feedback has been coming in for this driver
since it was applied.
* IIO_EVENT_CODE_EXTRACT_DIR bit mask was wrong and has been for a while
0xCF clearly doesn't give a contiguous bitmask.
* kxcjk-1013 range setting was failing to mask out the previous value
in the register and hence was 'enable only'.
* men_z188 device id table wasn't null terminated.
* bmg160 and bmc150 both failed to correctly handling an error in mode
setting.
* bmg160 and bmc150 both had a bug in setting the event direction in the
event spec (leads to an attribute name being incorrect)
* bmg160 defaulted to an open drain output for the interrupt - as a default
this obviously only works with some interrupt chips - hence change the
default to push-pull (note this is a new driver so we aren't going to
cause any regressions with this change).
* bmc150 had an unintuitive default for the rate of change (motion detector)
so change it to 0 (new driver so change of default won't cause any
regressions).

Some regulators support their operating mode to be changed on startup
or by consumers when the system is running while others only support
their operating mode to be changed while the system has entered in a
suspend state.
The regulator Device Tree binding documents a set of properties to
configure the regulators operating modes from a FDT. This patch builds
on (40e20d6 regulator: of: Add support for parsing regulator_state for
suspend state) and adds support to parse those properties and fill the
regulator constraints so the regulator core can call the right suspend
handlers when the system enters into sleep.
The modes are defined in the Device Tree using the hardware specific
modes supported by the regulators. Regulator drivers have to define a
translation function that is used to map the hardware specific modes
to the standard ones.

Drivers can use the of_regulator_match() function to parse the regulator
init_data from DT. A match table is used to specify the name of the node
containing the regulators, the device node and to return the init_data
to the caller.
But also the static regulator descriptor is needed to correctly extract
some DT properties like the regulator initial and suspend modes. Use the
match table to pass that information.

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.

The "regulator-initial-mode" and "regulator-mode" DT properties allows
to configure the regulator operating modes at startup or when a system
enters into a susend state.
But these properties use as valid values the operating modes supported
by each device while the core deals with the standard operating modes.
So a mapping function is needed to translate from the hardware specific
modes to the standard ones.
This mapping is a non-varying configuration for each regulator, so add
a function pointer to struct regulator_desc that will allow drivers to
define their callback to do the modes translation.

Some regulators can run on different operating modes (opmodes). This
allows systems to choose the most efficient opmode for each regulator.
This patch builds on top of (291d761 regulator: Document binding for
regulator suspend state for PM state) adding a regulator-initial-mode
DT property to configure at startup the operating mode for regulators
that support changing its mode during normal operation and a property
regulator-mode to be used in the regulator-state-[mem/disk] nodes for
regulators that supports changing its operating mode when the system
enters in a suspend state.
The set of possible modes that a regulator can operate depends on the
hardware capabilities so a list of generic operating modes can't be
provided. Instead, each hardware binding should define the list of
valid operating modes for the regulators found on that device.

The drm_get_edid() function performs direct I2C accesses to read EDID
blocks, assuming that the monitor DDC interface is directly connected to
the I2C bus. It can't thus be used with HDMI encoders that control the
DDC bus and expose EDID blocks through a different interface.
Refactor drm_do_get_edid() to take a block read callback function
instead of an I2C adapter, and export it for direct use by drivers.
As in the general case the DDC bus is accessible by the kernel at the
I2C level, drivers must make all reasonable efforts to expose it as an
I2C adapter and use drm_get_edid() instead of abusing this function.

encoders regardless of their types needlessly and painfully complex in

their embedded encoder instance, or to turn all drm_encoder instances
into drm_slave_encoder instances.
Between the two evils, one must choose the lesser. Use drm_slave_encoder
