This is a very quiet release, there was no work on the core and a good
chunk of the updates were the result of conversions to use newer GPIO
APIs. We did gain support for Analog ADP5055 and TI TPS65214 devices,
and there's a new restart handler for the PCA9450 which allows devices
using it to be properly power cycled on reboot, but otherwise it's minor
fixes and API updates.

Instead of filling in the regulator description programatically,
store the data in a struct. This will make it a bit nicer to
introduce support for other BCM590xx chips besides the BCM59056.
To do this, add a new struct type, bcm590xx_reg_data, to store
all of the necessary information. Drop the old IS_LDO, IS_GPLDO...
macros in favor of the "type" field in this struct. Adapt the
old bcm590xx_reg struct to the new types.

'struct spmi_voltage_range' are only modified at runtime to compile a
field, n_voltages, that could be computed at compile time.
So, simplify spmi_calculate_num_voltages() and compute n_voltages at
compile time within the SPMI_VOLTAGE_RANGE macro.
Constifying these structures moves some data to a read-only section, so
increase overall security.

max20086_parse_regulators_dt() calls of_regulator_match() using an
array of struct of_regulator_match allocated on the stack for the
matches argument.
of_regulator_match() calls devm_of_regulator_put_matches(), which calls
devres_alloc() to allocate a struct devm_of_regulator_matches which will
be de-allocated using devm_of_regulator_put_matches().
struct devm_of_regulator_matches is populated with the stack allocated
matches array.
If the device fails to probe, devm_of_regulator_put_matches() will be
called and will try to call of_node_put() on that stack pointer,
generating the following dmesg entries:
max20086 6-0028: Failed to read DEVICE_ID reg: -121
kobject: '\xc0$\xa5\x03' (000000002cebcb7a): is not initialized, yet
kobject_put() is being called.
Followed by a stack trace matching the call flow described above.
Switch to allocating the matches array using devm_kcalloc() to
avoid accessing the stack pointer long after it's out of scope.
This also has the advantage of allowing multiple max20086 to probe
without overriding the data stored inside the global of_regulator_match.

When restarting a CPU powered by the PCA9450 power management IC, it
is beneficial to use the PCA9450 to power cycle the CPU and all its
connected peripherals to start up in a known state. The PCA9450 features
a cold start procedure initiated by an I2C command.
Add a restart handler so that the PCA9450 is used to restart the CPU.
The restart handler sends command 0x14 to the SW_RST register,
initiating a cold reset (Power recycle all regulators except LDO1, LDO2
and CLK_32K_OUT)
As the PCA9450 is a PMIC specific for the i.MX8M family CPU, the restart
handler priority is set just slightly higher than imx2_wdt and the PSCI
restart handler. This makes sure this restart handler takes precedence.

Add support for TPS65214 regulators (bucks and LDOs) to the TPS65219
Regulator Driver as the TPS65214/TPS65214/TPS65219 PMIC devices have
significant register map overlap. TPS65214 is a Power Management IC with 3
Buck regulators (like TPS65215/TPS65219) and has 2 LDOs (like TPS65215).

Isolate all changes involving TPS65215 regulator desc and range resources.
- 'chipid' will identify which PMIC to support, and the corresponding
chip_data struct element to use in probe(). The chip_data struct is
helpful for any new PMICs added to this driver. The goal is to add future
PMIC info to necessary structs and minimize probe() function edits.
- The probe() will now loop through common (overlapping) regulators first,
then device-specific structs identified in the chip_data struct.
- Add TI TPS65215 PMIC to the existing platform_device_id struct, so the
regulator probe() can handle which PMIC chip_data information to use.

The ROHM BD96802 PMIC is primarily intended to be used as a companion
PMIC extending the capabilities of the BD96802 but it can be used on
it's own as well. When used as a companion PMIC, the start-up and
shut-down sequences are usually intitiated by the master PMIC using IF
pins.
The BD96802 looks from the digital interface point of view pretty much
like a reduced version of BD96801. It includes only 2 BUCKs and provides
the same error protection/detection mechanisms as the BD96801. Also, the
voltage control logic is same up to the register addresses.
Add support for controlling BD96802 using the BD96801 driver.

The resources generated in the BD96801 MFD driver are only visible to
the sub-drivers whose resource fields they are added. This makes
abbreviating the resource name with the IC name pointless. It just adds
confusion in those sub-drivers which do not really care the exact model
that generates the IRQ but just want to know the purpose IRQ was
generated for. Thus, as a preparatory fix to simplify adding support for
ROHM BD96802 PMIC the IC name "bd96801-" prefix was dropped from the IRQ
resource names. Adapt the regulator driver to this change.

I'm working on integrating a system with a MAX20086 and noticed these
small issues in the driver: the chip ID for MAX20086 is 0x30 and not
0x40. Also, in my use case, the enable pin is always enabled by
hardware, so the enable GPIO isn't needed. Without these changes, the
driver fails to probe.
The enable pin can be configured as always enabled by the hardware. Make
the enable gpio request optional so the driver doesn't fail to probe

This has been a very quiet release, we've got support for one device
added, another removed, and some smaller fixes and API improvements.
The main thing of note is the rework of the PCA9450 LDO5 handling:
- A rework of the handling of LDO5 on the PCA9450, this was quite wrong
in how it handled the SD_VSEL conrol and only worked for some system
designs. This includes a DTS update since there was a not quite ABI
compatible change as part of the fix.
- A devres change introducing devm_kmemdup_array() was pulled in so it
could be used with some regulator conversions to that function, this
pulled in some other devres and IIO stuff that was part of the same pull
request.
- Removal of the PCF50633 driver, the SoC for the OpenMoko platform
that used it has been removed.
- Support for the NXP PF9453.

If 'ctr_bit' is negative, the shift counts become negative, causing a
shift of bounds and undefined behavior.
Presumably that's not possible in normal operation, but the code
generation isn't optimal. And undefined behavior should be avoided
regardless.
Improve code generation and remove the undefined behavior by converting
the signed variables to unsigned.
