At the moment there is an implicit relationship between the AXP model
IDs and the order of the strings in the axp20x_model_names[] array.
This is fragile, and makes adding IDs in the middle error prone.
Make this relationship official by changing the ID type to the actual
enum used, and using indexed initialisers for the string list.

Merge series from Jerome Brunet <jbrunet@baylibre.com>:
This patchset groups the regulator patches around the init_data topic
discussed on pmbus write protect patchset [1]

The rk808-regulator driver supports multiple PMIC variants from the Rockckip
RK80x and RK81x series, but the DVS GPIOs are supported on the RK808 variant
only, according to the DT bindings [1][2][3][4][5][6] and the datasheets for
the supported PMIC variants. [7][8][9][10][11][12]
Thus, change the probe path so the "dvs-gpios" property is checked for and
its value possibly used only when the handled PMIC variant is RK808. There's
no point in doing that on the other PMIC variants, because they don't support
the DVS GPIOs, and it goes against the DT bindings to allow a possible out-
of-place "dvs-gpios" property to actually be handled in the driver.
This eliminates the following messages, emitted when the "dvs-gpios" property
isn't found in the DT, from the kernel log on boards that actually don't use
the RK808 variant, which may have provided a source of confusion:
rk808-regulator rk808-regulator.2.auto: there is no dvs0 gpio
rk808-regulator rk808-regulator.2.auto: there is no dvs1 gpio
Furthermore, demote these kernel messages to debug messages, because they are
useful during the board bringup phase only. Emitting them afterwards, on the
boards that use the RK808 variant, but actually don't use the DVS0/1 GPIOs,
clutters the kernel log a bit, while they provide no value and may actually
cause false impression that some PMIC-related issues are present.

The machine specific regulator_init() appears to be unused.
It does not allow a lot of interaction with the regulator framework,
since nothing from the framework is passed along (desc, config,
etc ...)
Machine specific init may also be done with the added init_cb() in
the regulator description, so remove regulator_init().

Provide an initialisation callback to handle runtime parameters.
The idea is similar to the regulator_init() callback, but it provides
regulator specific structures, instead of just the driver specific data.
As an example, this allows the driver to amend the regulator constraints
based on runtime parameters if necessary.

On DT platforms, if a regulator init_data is provided in config, it is
silently ignored in favor of the DT parsing done by the framework, if
of_match is set.
of_match is an indication that init_data is expected to be set based on DT
and the parsing should be done by the regulator framework.
If the regulator provider passed init_data it must be because it is useful
somehow, in such case of_match should be clear.
If the driver expects the framework to initialize this data on its
own, it should leave init_data clear.
Warn if both init_data and of_match are set, then default to the provided
init_data.

Merge series from Chen-Yu Tsai <wenst@chromium.org>:
At ELCE, Sebastian told me about his recent work on adding regulator
supply support to the Rockchip power domain driver [2], how the MediaTek
driver has been using the existing devm_regulator_get() API and
reassigning different device nodes to the device doing the lookup, and
how the new of_regulator_get_optional() is the proper fit for this.
Patch 1 adds a new of_regulator_get_optional() function to look up
regulator supplies using device tree nodes.
Patch 2 adds a devres version of the aforementioned function at
Sebastian's request for the two power domain drivers.

i2c_device_id::driver_data to 0
These drivers don't use the driver_data member of struct i2c_device_id,
so don't explicitly initialize this member.
This prepares putting driver_data in an anonymous union which requires
either no initialization or named designators. But it's also a nice
cleanup on its own.
While touching the initializer, also remove the comma after the sentinel
entry.

There are existing uses for a devres version of of_regulator_get_optional()
in power domain drivers. On MediaTek platforms, power domains may have
regulator supplies tied to them. The driver currently tries to use
devm_regulator_get() to not have to manage the lifecycle, but ends up
doing it in a very hacky way by replacing the device node of the power
domain controller device to the device node of the power domain that is
currently being registered, getting the supply, and reverting the device
node.
Provide a better API so that the hack can be replaced.

The to-be-introduced I2C component prober needs to enable regulator
supplies (and toggle GPIO pins) for the various components it intends
to probe. To support this, a new "pure DT lookup" method for getting
regulator supplies is needed, since the device normally requesting
the supply won't get created until after the component is probed to
be available.
Add a new of_regulator_get_optional() function for this. This mirrors
the existing regulator_get_optional() function, but is OF-specific.
The underlying code that supports the existing regulator_get*()
functions has been reworked in previous patches to support this
specific case.
Also convert an existing usage of "dev && dev->of_node" to
"dev_of_node(dev)".

_regulator_get() contains a lot of common code doing checks prior to the
regulator lookup and housekeeping work after the lookup. Almost all the
code could be shared with a OF-specific variant of _regulator_get().
Split out the common parts so that they can be reused. The OF-specific
version of _regulator_get() will be added in a subsequent patch.
No functional changes were made.

The behavior of regulator_dev_lookup() for non-DT way has been broken
since the commit b8c325545714 ("regulator: Move OF-specific regulator
lookup code to of_regulator.c").
Before the commit, of_get_regulator() was used to get the regulator,
which returns NULL if the regulator is not found. So the regulator
will be looked up through regulator_lookup_by_name() if no matching
regulator is found in regulator_map_list.
However, currently, of_regulator_dev_lookup() is used to instead of
of_get_regulator(), but the variable 'r' is set to ERR_PTR(-ENODEV)
instead of NULL if the regulator is not found. In this case, if no
regulator is found in regulator_map_list, the variable 'r' is still
ERR_PTR(-ENODEV), So regulator_dev_lookup() returns the value of 'r'
directly instead of continuing to look up the regulator through
regulator_lookup_by_name().

'struct regulator_desc' is not modified in this driver.
Constifying this structure moves some data to a read-only section, so
increase overall security, especially when the structure holds some
function pointers.

Merge series from Andre Przywara <andre.przywara@arm.com>:
This is remainder of the AXP717 fix series, containing support for the
boost regulator. This is meant to increase the battery voltage to the 5
volts required to provide the USB VBUS power.
It's the usual trinity of DT bindings patch (1/3), the MFD part
describing the PMIC registers (2/3) and the final patch to model the
regulator (3/3).
Compared to v2, this drops the merged patches, and just retains the
boost related parts. It also changes the internal name of the register
to AXP717_MODULE_EN_CONTROL_2, since there is another control register
we will need later for battery support.

The AXP717 also contains an adjustable boost regulator, to provide the
5V USB VBUS rail when running on battery.
Add the regulator description that states the voltage range this
regulator can cover.

There's still a bit of OF-specific code in the regulator device lookup
function.
Move those bits of code over to of_regulator.c, and create a new
function of_regulator_dev_lookup() to encapsulate the code moved out of
regulator_dev_lookup().
Also mark of_find_regulator_by_node() as static, since there are no
other users in other compile units.
There are no functional changes. A line alignment was also fixed.

Previous commits cleaning up kerneldoc used the term "negative error
number" to refer to error condition return values. Update remaining
instances of other terminology such as "error code" or "errno" as
well so the whole regulator subsystem is unified.

of_regulator_bulk_get_all() has a comment section that pretty much
resembles a kerneldoc block, except that the block begins with "/*"
instead of "/**".
Fix that and also rework the "Return" section and the error code
terminology so that it is the same as the other kerneldoc blocks
in the same file.
Fixes: 27b9ecc7a9ba ("regulator: Add of_regulator_bulk_get_all")
