Depending on the phase selection (single or multi), the FPWM bits
configured forces the regulator to operate in PWM mode. In case of
multi-phase selection, the FPWM_MP bits enforce the regulator to also
operate in multi-phase. This fixes correct multi-phase operation.

While at this, correct incorrect macro alignment as well.

Casey Connolly <casey.connolly@linaro.org> says:

This series implements various improvements to Linux header
compatibility, largely in preparation for a full port of Linux CCF but
many of these changes would also be helpful when porting other drivers.

Beside the basic header/compat stuff there are a few larger patches:

Patch 1 adds the "%pOF" format specifier to vsprintf, this behaves the
same as it does in Linux printing the name of the ofnode, but notably it
expects an ofnode pointer rather than a device_node.

Patch 2 adds an option to skip doing a full DM scan pre-relocation.
Some platforms like Qualcomm don't actually need devices to be probed
prior to relocation, it is also quite slow to scan the entire FDT before
caches are up. This option gets us to main loop 30-50% faster.

Unfortunately it isn't possible to totally skip DM since U-Boot will
panic if it can't find a serial port, but the serial uclass code will
bind the serial port itself by reading /chosen/stdout-path, however any
dependencies like clocks won't be found so this should only be enabled
if the serial driver gracefully handles missing clocks.

Patch 3 adds [k]strdup_const(), this works the same as the Linux version
saving a small amount of memory by avoiding duplicating strings stored
in .rodata, this is particularly useful for CCF.

Patch 4 adds 64-bit versions of some 32-bit ofnode utilities functions,
making it possible to parse 64-bit arrays.

Patch 6 provides a simple implementation of kref, this will be used
by CCF.

Patch 9 adds devm_krealloc() support to devres, it relies on storing
allocation sizes in the devres struct which will add a small overhead.

These just wrap regulator_set_enable() and provide a closer analogue to
the Linux API.

The bit_offset_from_cpcap_lowest_voltage value was inherited from the
downstream kernel as a quirk. With the correct voltage table, it is no
longer needed. An additional benefit is that SW1, SW2, and SW4 now share
the same voltage table.

Add a new regulator driver for MT6359P and similar PMIC chips.

The MT6359P is a eco version for MT6359 regulator. For the MT8391
platform, we use the MT6359P (MT6365) as the main PMIC. The MT6359 and
MT6359P have different register maps. Therefore, on the MT8391 platform,
we only provide support for the MT6359P. If support for the MT6359 PMIC
it can be added later.

Samsung's S2MPU05 PMIC is used by Exynos7870 SoC. It has 5 buck and 38
LDO regulators. Add support for this device variant in the driver.

In the Linux kernel driver, all information related to LDO and BUCK
regulators are stored in descriptive arrays. This also allows multiple
variants to be supported by the same driver.

Define a struct sec_regulator_desc which holds all values required by a
regulator. Create an array of said struct containing all regulators. The
descriptors are designed to follow a style similar to what's seen in the
Linux driver, so comparing one with the other is simple.

In functions such as s2mps11_{buck,ldo}_{val,mode} these values are to
be used, make necessary modifications to pull them from the descriptors.
Since multiple variants have varying descriptors, select them from
within a switch-case block.

Functions s2mps11_{buck,ldo}_{volt2hex,hex2volt} and arrays
s2mps11_buck_{ctrl,out} are phased out as the calculations are now
hardcoded in descriptors, thusly, it reduces clutter and enhances
readability.

Two macros in s2mps11.h, S2MPS11_LDO_NUM and S2MPS11_BUCK_NUM are
removed as they are no longer being used.

There are multiple PMICs by Samsung which are similar in architecture
(register layout, interface, etc.) and is possible to be driven by a
single driver. Variant specific code and data should be managed properly
in the driver.

And an enum which describes all supported variants. Pass the enum as the
device driver data. Introduce a switch-case block on the enum for any
variant specific code.
