Krzysztof Kozlowski b8f139f68f regulator/mfd: max14577: Export symbols for calculating charger current
This patch prepares for changing the max14577 charger driver to allow
configuring battery-dependent settings from DTS.

The patch moves from regulator driver to MFD core driver and exports:
 - function for calculating register value for charger's current;
 - table of limits for chargers (MAX14577, MAX77836).

Previously they were used only by the max14577 regulator driver. In next
patch the charger driver will use them as well. Exporting them will
reduce unnecessary code duplication.

Maxime Ripard 0d90ecf31e regulator: axp20x: Use parent device as regulator configuration device
The current device used for the regulator configuration is the child device
created by the MFD driver. This means that it doesn't have any of_node pointing
to it, and whenever we register the regulators, it will not look into the
regulator supply in the DT, hence requiring to provide regulator aliases in the
MFD driver.

We can easily fix that by using the parent device in our configuration, which
has a DT node associated to it, and will allow a DT lookup. Eventually, we will
be able to remove the aliases in the MFD driver.

Silergy SYR82x regulators share the exact same functionality and register layout
as the Fairchild FAN53555 regulators. Therefore extend the driver to add
support for them.

Both types use the same vendor id in their ID1 register, so it's not possible
to distinguish them automatically.

Similarly, the types also do not match. Type 8 used by the SYR827 and SYR828
start at 712.5mV and increment in 12.5mv steps, while the FAN53555 type 8
starts at 600mV and increments in 10mV steps.

Mark Brown a0c7b164ad regulator: of: Provide simplified DT parsing method
Currently regulator drivers which support DT all repeat very similar code
to supply a list of known regulator identifiers to be matched with DT,
convert that to platform data which is then matched up with the regulators
as they are registered. This is both fiddly to get right and for devices
which can use the standard helpers to provide their operations is the main
source of code in the driver.

Since this code is essentially identical for most drivers we can factor it
out into the core, moving the identifiers in the match table into the
regulator descriptors and also allowing drivers to pass in the name of the
subnode to search. When a driver provides an of_match string for the
regulator the core will attempt to use that to obtain init_data, allowing
the driver to remove all explicit code for DT parsing and simply provide
data instead.

The current code leaks the phandles for the child nodes, this will be
addressed incrementally and makes no practical difference for FDT anyway
as the DT data structures are never freed.

Guodong Xu b8b27a44dd regulator: remove unnecessary of_node_get() to parent
These of_node_get() were added to balance refcount decrements inside of
of_find_node_by_name().
See: commit c92f5dd2c4 ("regulator: Add missing of_node_put()")

However of_find_node_by_name() was then replaced by of_get_child_by_name(),
which doesn't call of_node_put() against its input parameter.

So, need to remove these unnecessary of_node_get() calls.
