On Odroid XU3/4 and other Exynos5422 based boards there is a case, that
different devices on the board are supplied by different regulators
with non-fixed voltages. If one of these devices temporarily requires
higher voltage, there might occur a situation that the spread between
two devices' voltages is so high, that there is a risk of changing
'high' and 'low' states on the interconnection between devices powered
by those regulators.
Uncoupled regulators should be a special case of coupled regulators, so
they should share a common voltage setting path. When enabling,
disabling or setting voltage of a coupled regulator, all coupled
regulators should be locked. Regulator's supplies should be locked, when
setting voltage of a single regulator. Enabling a coupled regulator or
setting its voltage should not be possible if some of its coupled
regulators, has not been registered.
Add function for locking coupled regulators and supplies. Extract
a new function regulator_set_voltage_rdev() from

Introduce new function regulator_balance_voltage(), which
keeps max_spread constraint fulfilled between a group of coupled
regulators. It should be called if a regulator changes its
voltage or after disabling or enabling. Disabled regulators should
follow changes of the enabled ones, but their consumers' demands
shouldn't be taken into account while calculating voltage of other
coupled regulators.
Find voltages, which are closest to suiting all the consumers' demands,
while fulfilling max_spread constraint, keeping the following rules:
- if one regulator is about to rise its voltage, rise others
voltages in order to keep the max_spread
- if a regulator, which has caused rising other regulators, is
lowered, lower other regulators if possible
- if one regulator is about to lower its voltage, but it hasn't caused
rising other regulators, don't change its voltage if it breaks the
max_spread
Change regulators' voltages step by step, keeping max_spread constraint
fulfilled all the time. Function regulator_get_optimal_voltage()
should find the best possible change for the regulator, which doesn't
break max_spread constraint. In function regulator_balance_voltage()
optimize number of steps by finding highest voltage difference on
each iteration.
If a regulator, which is about to change its voltage, is not coupled,
method regulator_get_optimal_voltage() should simply return the lowest
voltage fulfilling consumers' demands.
Coupling should be checked only if the system is in PM_SUSPEND_ON state.

Setting voltage, enabling/disabling regulators requires operations on
all regulators related with the regulator being changed. Therefore,
all of them should be locked for the whole operation. With the current
locking implementation, adding additional dependency (regulators
coupling) causes deadlocks in some cases.
Introduce a possibility to attempt to lock a mutex multiple times
by the same task without waiting on a mutex. This should handle all
reasonable coupling-supplying combinations, especially when two coupled
regulators share common supplies. The only situation that should be
forbidden is simultaneous coupling and supplying between a pair of
regulators.
The idea is based on clk core.

Regulators attached via RPMh on Qualcomm sdm845 apparently are
write-only. Specifically you can send a request for a certain voltage
but you can't read back to see what voltage you've requested. What
this means is that at bootup we have absolutely no idea what voltage
we could be at.
As discussed in the patches to try to support the RPMh regulators [1],
the fact that regulators are write-only means that its driver's
get_voltage_sel() should return an error code if it's called before
any calls to set_voltage_sel(). This causes problems in
machine_constraints_voltage() when trying to apply the constraints.
A proposed fix was to come up with an error code that could be
returned by get_voltage_sel() which would cause the regulator
framework to simply try setting the voltage with the current
constraints.
In this patch I propose the error code -ENOTRECOVERABLE. In errno.h
this error is described as "State not recoverable". Though the error
code was originally intended "for robust mutexes", the description of
the error code seems to apply here because we can't read the state of
the regulator. Also note that the only existing user of this error
code in the regulator framework is tps65090-regulator.c which returns
this error code from the enable() call (not get_voltage() or
get_voltage_sel()), so there should be no existing regulators that
might accidentally get the new behavior. (Side note is that tps65090
seems to interpret this error code to mean an error that you can't
recover from rather than some data that can't be recovered).

If device tree is not enabled, of_find_regulator_by_node() should have

This is to fix build error after CONFIG_NO_AUTO_INLINE is introduced.
If this option is enabled, GCC will not auto-inline functions that are
not explicitly marked as inline.
In this case (no CONFIG_OF), the copmiler will report error in function
regulator_dev_lookup().
W/O NO_AUTO_INLINE, function of_get_regulator() is auto-inlined and then
the call to of_find_regulator_by_node() is optimized out since
of_get_regulator() always return NULL.
W/ NO_AUTO_INLINE, the return value of of_get_regulator() is a variable

The BD9571MWV PMIC supports backup mode, which keeps one or more DDR
rails powered while the main SoC is powered down.
Which DDR rails are to be kept powered is board-specific, and controlled
using the optional "rohm,ddr-backup-power" DT property. In the absence
of this property, backup mode is not available.
Backup mode can be enabled or disabled by the user using the standard
"wakeup" virtual file in sysfs, e.g. to enable:
echo enabled > /sys/devices/platform/soc/e60b0000.i2c/i2c-7/7-0030/bd9571mwv-regulator.2.auto/power/wakeup
When the PMIC is configured for backup mode, the role of the accessory
power switch changes from a power switch to a wake-up switch.
Two types of switches (or signals) can be used:
A. With a momentary power switch (or pulse signal), the PMIC is
configured for backup mode in the PMIC driver's suspend callback,
during system suspend.
Backup mode is enabled by default, as there is no further impact
during normal system operation.
B. With a toggle power switch (or level signal), the following steps
must be followed exactly:
1. Configure PMIC for backup mode,
2. Switch accessory power switch off, to prepare for system
suspend, which is a manual step not controlled by software,
3. Suspend system.
This mode is not yet supported by the driver.
As the switch type is board-specific, and cannot be determined
automatically, it is obtained from the presence of one of the
"rohm,rstbmode-*" properties in DT.

In of_get_regulation_constraints() we were taking the result of
of_map_mode() (an unsigned int) and assigning it to an int. We were
then checking whether this value was -EINVAL. Some implementers of
of_map_mode() were returning -EINVAL (even though the return type of
their function needed to be unsigned int) because they needed to
signal an error back to of_get_regulation_constraints().
In general in the regulator framework the mode is always referred to
as an unsigned int. While we could fix this to be a signed int (the
highest value we store in there right now is 0x8), it's actually
pretty clean to just define the regulator mode 0x0 (the lack of any
bits set) as an invalid mode. Let's do that.

This is a set of minor (and safe changes) that didn't make the initial
pull request plus some bug fixes. The status handling code is
actually a running regression from the previous merge window which had
an incomplete fix (now reverted) and most of the remaining bug fixes
are for problems older than the current merge window.

[ Side note: this merge also takes the base kernel git repository to 6+
million objects for the first time. Technically we hit it a couple of
merges ago already if you count all the tag objects, but now it
reaches 6M+ objects reachable from HEAD.
I was joking around that that's when I should switch to 5.0, because
3.0 happened at the 2M mark, and 4.0 happened at 4M objects. But
probably not, even if numerology is about as good a reason as any.
