regulator: qcom_spmi: add support for HT_P150
HT_P150 is a LDO PMOS regulator based on LV P150 using HFS430 layout
found in PMP8074 and PMS405 PMIC-s.

Both PMP8074 and PMS405 define the programmable range as 1.616V to 3.304V
but the actual MAX output voltage depends on the exact LDO in each of
the PMIC-s.

It has a max current of 150mA, voltage step of 8mV.

regulator: max597x: Remove unused including <linux/version.h>
The patch makes sense but these are not compile warnings.
They come from scripts/checkversion.pl, which can be called
by 'make versioncheck', so I suppose that something in your
build system is running 'make versioncheck'.

Eliminate the follow versioncheck warning:

./drivers/regulator/max597x-regulator.c: 21 linux/version.h not needed.

regulator: qcom_smd: Add PM8909 RPM regulators
The set of regulators available in the PM8909 PMIC is similar to PM8916
which is already supported by the driver. s3, s4 and l16 are missing.
However, probing the SPMI hardware identification registers using the
qcom_spmi-regulator driver reveals that the regulators in PM8909 are
actually some kind of mixture between PM8916 and PM8226:

  - ult_lo_smps (= pm8916_buck_lvo_smps): s1
  - ult_ho_smps (= pm8916_buck_hvo_smps): s2
  - ult_nldo (= pm8916_nldo): l1, l2, l3, l10
  - ult_pldo (= pm8916_pldo): l4, l8, l9, l12-l15, l17, l18
  - pldo (= pm8226_pldo): l5, l6, l7, l11

Use this mapping to add the rpm_regulator_data for PM8909 by reusing
the existing regulator definitions.

e8977917e1
regulator: qcom_smd: Fix pm8916_pldo range
The PM8916 device specification [1] documents a programmable range of
1.75V to 3.337V with 12.5mV steps for the PMOS LDOs in PM8916. This
range is also used when controlling the regulator directly using the
qcom_spmi-regulator driver ("ult_pldo" there).

However, for some reason the qcom_smd-regulator driver allows a much
larger range for the same hardware component. This could be simply a
typo, since the start of the range is essentially just missing a '1'.

In practice this does not cause any major problems, since the driver
just sends the actual voltage to the RPM firmware instead of making use
of the incorrect voltage selector. Still, having the wrong range there
is confusing and prevents the regulator core from validating requests
correctly.

'gpiod_get_from_of_node' only parse the 'enable' property, it need to
add the gpio suffix. It's more convenient to use fwnode_gpiod_get_index.
Although fwnode parsing is not preferred, but 'of_parse_cb' already can

regulator: core: Fix enable_count imbalance with EXCLUSIVE_GET
Since the introduction of regulator->enable_count, a driver that did
an exclusive get on an already-enabled regulator would end up with
enable_count initialized to 0 but rdev->use_count initialized to 1.
With that starting point the regulator is effectively stuck enabled,
because if the driver attempted to disable it it would fail the
enable_count underflow check in _regulator_handle_consumer_disable().

The EXCLUSIVE_GET path in _regulator_get() now initializes
enable_count along with rdev->use_count so that the regulator can be
disabled without underflowing the former.

regulator: core: Sleep (not delay) in set_voltage()
These delays can be relatively large (e.g., hundreds of microseconds to
several milliseconds on RK3399 Gru systems). Per
Documentation/timers/timers-howto.rst, that should usually use a
sleeping delay. Let's use the existing regulator delay helper to handle
both large and small delays appropriately. This avoids burning a bunch
of CPU time and hurting scheduling latencies when hitting regulators a
lot (e.g., during cpufreq).

The sleep vs. delay issue choice has been made differently over time --
early versions of RK3399 Gru PWM-regulator support used usleep_range()
in pwm-regulator.c. More of this got moved into the regulator core,
in commits like:

73e705bf81 regulator: core: Add set_voltage_time op

At the same time, the sleep turned into a delay.

It's OK to sleep in _regulator_do_set_voltage(), as we aren't in an
atomic context. (All our callers grab various mutexes already.)

I avoid using fsleep() because it uses a usleep_range() of [N to N*2],
and usleep_range() very commonly biases to the high end of the range. We
don't want to double the expected delay, especially for long delays.

This happend when da9121 device is probe by da9121_i2c_id, but with
invalid dts. Thus, chip->subvariant_id is set to -EINVAL, and later
da9121_assign_chip_model() will access 'regmap' without init it.

Fix it by return -EINVAL from da9121_assign_chip_model() if
'chip->subvariant_id' is invalid.

regulator: Flag uncontrollable regulators as always_on
While we currently assume that regulators with no control available are
just uncontionally enabled this isn't always as clearly displayed to
users as is desirable, for example the code for disabling unused
regulators will log that it is about to disable them. Clean this up a
bit by setting always_on during constraint evaluation if we have no
available mechanism for controlling the regualtor so things that check
the constraint will do the right thing.

regulator: wm8994: Add an off-on delay for WM8994 variant
As per Table 130 of the wm8994 datasheet at [1], there is an off-on
delay for LDO1 and LDO2.  In the wm8958 datasheet [2], I could not
find any reference to it.  I could not find a wm1811 datasheet to
double-check there, but as no one has complained presumably it works
without it.

This solves the issue on Samsung Aries boards with a wm8994 where
register writes fail when the device is powered off and back-on
quickly.
