Merge series from Stephan Gerhold <stephan.gerhold@kernkonzept.com>:

Fix the voltage range for the pm8916_pldo in the qcom_smd-regulator
driver and add definitions for the regulators available in PM8909.

In scmi_regulator_probe(), of_find_node_by_name() will decrease
the refcount of its first argument and we need a of_node_get()
to keep reference balance.

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.

Document the "qcom,rpm-pm8909-regulators" compatible for describing
the regulators available in the PM8909 PMIC (controlled via the RPM
firmware).

PM8909 is very similar to the existing PM8916 but lacks 3 of the
regulators (s3, s4 and l16).

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.

From the common binding, 'enable-gpio' or 'enable-gpios' are all well
for external 'enable' gpio.

'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
guarantee the callback will only be used by regulator of_node parsing.

backlight_properties.fb_blank is deprecated. The states it represents
are handled by other properties; but instead of accessing those
properties directly, drivers should use the helpers provided by
backlight.h.

Instead of retrieving the backlight brightness in struct
backlight_properties manually, and then checking whether the backlight
should be on at all, use backlight_get_brightness() which does all
this and insulates this from future changes.

According to the datasheet:
Buck range is 0.6-2.1875V with a 12.5mV step
LDO range is 0.8-3.975V with a 25mV step.

So, correct the ranges according to the datasheet[1].

  delayacct: track delays from write-protect copy

The bluetooth code uses our bitmap infrastructure for the two bits (!)
of connection setup flags, and in the process causes odd problems when
it converts between a bitmap and just the regular values of said bits.

It's completely pointless to do things like bitmap_to_arr32() to convert
a bitmap into a u32.  It shoudln't have been a bitmap in the first
place.  The reason to use bitmaps is if you have arbitrary number of
bits you want to manage (not two!), or if you rely on the atomicity
guarantees of the bitmap setting and clearing.

The code could use an "atomic_t" and use "atomic_or/andnot()" to set and
clear the bit values, but considering that it then copies the bitmaps
around with "bitmap_to_arr32()" and friends, there clearly cannot be a
lot of atomicity requirements.

So just use a regular integer.

In the process, this avoids the warnings about erroneous use of
bitmap_from_u64() which were triggered on 32-bit architectures when
conversion from a u64 would access two words (and, surprise, surprise,
only one word is needed - and indeed overkill - for a 2-bit bitmap).

That was always problematic, but the compiler seems to notice it and
warn about the invalid pattern only after commit 0a97953f ("lib: add
bitmap_{from,to}_arr64") changed the exact implementation details of
'bitmap_from_u64()', as reported by Sudip Mukherjee and Stephen Rothwell.
