Add the necessary definitions for the PMA8084 PMIC to the
qcom_spmi-regulator driver to allow reading the actual voltages applied
to the hardware at runtime. This is mainly intended for debugging since
the regulators are usually controlled through the RPM firmware (via
qcom_smd-regulator).

regulator_register()"
This reverts commit 5f4b204b6b8153923d5be8002c5f7082985d153f.
Since rdev->dev now has a release() callback, the proper way of freeing
the initialized device can be restored.

When fixing a memory leak in commit d3c731564e09 ("regulator: plug
of_node leak in regulator_register()'s error path") it moved the
device_initialize() call earlier, but did not move the `dev->class`
initialization. The bug was spotted and fixed by reverting part of
the commit (in commit 5f4b204b6b81 "regulator: core: fix kobject
release warning and memory leak in regulator_register()") but
introducing a different bug: now early error paths use `kfree(dev)`
instead of `put_device()` for an already initialized `struct device`.
Move the missing assignments to just after `device_initialize()`.

Merge series from Chen-Yu Tsai <wenst@chromium.org>:
Hi,
This is v3 of the remainder of the MT6358 regulator driver cleanup
and improvement series. v1 can be found here [1]; v2 is here [2].
Changes since v2:
- Merged patches dropped
- Fixed up pickable linear ranges' selector values
- Collected tags
- Patch adding missing regulator definitions squashed into patch using
the definitions; recommended by Krzysztof on my MT6366 series.
- Remaining dts patch split out to be sent separately
Changes since v1:
- Merged patches dropped
- Added patch to move VCN33 regulator status sync after ID check
- Added patch to fix VCN33 sync fail error message
- Added patch to add missing register definitions
Various discrepancies were found while preparing to upstream MT8186
device trees, which utilize the MT6366 PMIC, that is also covered by
this driver.
Patches 1~3 should go through the regulator tree, and patch 4 through
the soc/mediatek tree.
** Note: patch 2 needs an ack from Lee for the mfd header change.
This v3 series can be seen as two parts. v1 had three parts, but one
part was fully merged, and then v2 gained another cleanup. v3 drops
the "fixing bogus regulators" part: driver changes are fully merged
and device tree change will be sent separately.
Part 1 - Robust chip ID checking (patch 1)
Angelo suggested making the driver fail to probe if an unexpected chip
ID was found. Patch 1 implements this.
Part 2 - Output voltage fine tuning support (patches 2, 3)
Many of the LDOs on these PMIC support an extra level of output voltage
fine tuning. Most default to no offset, but a couple have a non-zero
offset by default. Previously this was unaccounted for in the driver and
device tree constraints. On the outputs with non-zero offset, this ends
up becoming a discrepancy between the device tree and actual hardware.
These two patches adds support for this second level of tuning, modeled
as bunch of linear ranges. While it's unlikely we need this level of
control, it's nice to be able to read back the accurate hardware
settings.
Please have a look.
Thanks
ChenYu

Some of the LDO regulators in the MT6358/MT6366 have sparsely populated
voltage tables, supported by custom get/set operators. While it works,
it requires more code and an extra field to store the lookup table.
These LDOs also have fine voltage calibration settings that can slightly
boost the output voltage from 0 mV to 100 mV, in 10 mV increments.
These combined could be modeled as a pickable set of linear ranges. The
coarse voltage setting is modeled as the range selector, while each
range has 11 selectors, starting from the range's base voltage, up to
+100 mV, in 10mV increments.

The "fixed" LDO regulators found on the MT6358 and MT6366 PMICs have
either no voltage selection register, or only one valid setting.
However these do have a fine voltage calibration setting that can
slightly boost the output voltage from 0 mV to 100 mV, in 10 mV
increments.
Add support for this by changing these into linear range regulators.
Some register definitions that are missing are also added.

The MT6358 and MT6366 PMICs, and likely many others from MediaTek, have
a chip ID register, making the chip semi-discoverable.
The driver currently supports two PMICs and expects to be probed on one
or the other. It does not account for incorrect mfd driver entries or
device trees. While these should not happen, if they do, it could be
catastrophic for the device. The driver should be sure the hardware is
what it expects.
Make the driver fail to probe if the chip ID presented is not a known
one.

Prepare for the coming implementation by GCC and Clang of the __counted_by
attribute. Flexible array members annotated with __counted_by can have
their accesses bounds-checked at run-time checking via CONFIG_UBSAN_BOUNDS
(for array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family
functions).
As found with Coccinelle[1], add __counted_by for struct mc13xxx_regulator_priv.

The buck and linear range LDO (VSRAM_*) regulators share one set of ops.
This set includes support for get/set mode. However this only makes
sense for buck regulators, not LDOs. The callbacks were not checking
whether the register offset and/or mask for mode setting was valid or
not. This ends up making the kernel report "normal" mode operation for
the LDOs.
Create a new set of ops without the get/set mode callbacks for the
linear range LDO regulators.

Some configurations differ between chip variants, e,g. the register
to control the on of state of LDOA1 and SWB2. Thus, it is necessary
to choose the correct configuration for a dedicated device.
If the wrong configuration was used, the LDOA1 output that was
disabled by the bootloader was enabled in Kernel again.
Each chip variant gets its dedicated configuration selected by
the chip ID previously collected from MFD probe function.
The VTT enum value (tps65086_regulators) is shifted because not all
chip variants have a separate SWB2 switch. Sometimes they are merged.
So the configuration possibilities differ, thus the regulator
configuration arrays have a different length.

The clk_register_clkdev() allocates memory by calling vclkdev_alloc() and
this memory is not freed in the error path. Similarly, resources allocated
by clk_register_fixed_rate() are not freed in the error path.
Fix these issues by using devm_clk_hw_register_fixed_rate() and
devm_clk_hw_register_clkdev().
After this, the static variable clk is not needed. Replace it with
local variable hw in probe() and drop calling clk_unregister_fixed_rate()
from raa215300_rtc_unregister_device().

Use the helper function devm_kmemdup() rather than duplicating its
implementation, which helps to enhance code readability.

Since the driver tps6286x-regulator depends on CONFIG_OF,
it makes no difference to wrap of_match_ptr() here.
Remove of_match_ptr() macros to clean it up.
