ROHM BD72720 is a power management IC which integrates 10 buck and 11 LDO
regulators. This PMIC has plenty of commonalities with the BD71828 and
BD71879.
The BD72720 does also have similar 'run-level'-concept as the BD71828 had.
It allows controlling the regulator's 'en masse', although only BUCK1
and LDO1 can utilize this in BD72720. Similar to BD71828, this 'en
masse' -control is not supported by this driver.
Support the voltage and enable/disable state control for the BD72720.

Add a driver for the TPS65185 regulator which provides the

To simplify things, include the hwmon part directly which is only
one temperature sensor and there are no other functions besides regulators
in this chip.
Add a driver for the TPS65185 regulator. Implement handling of the various
gpio pins. Because the PWRUP (=enable) pin functionality can be achieved
by just using two bits instead, just ensure that it is set to a stable
value.
Implement the pair of symmetric LDOs as a single regulator because they
share a single voltage set register. As the VCOM regulator sits behind that
machinery, just define that one as a supply.
For simplicity, just add the temperature sensor (depending on external NTC)
directly.
There is a mechanism to measure some kick-back voltage during a defined EPD
operation, to calibrate the VCOM voltage setting and store that
non-volatile in the chip to be the power up default setup. That is not
implemented yet in the driver, but that also means that there is a
non-factory default value in these registers after power-up.

Add a driver for the FP9931/JD9930 regulator which provides the
comparatively high voltages needed for electronic paper displays.
Datasheet for the FP9931 is at
https://www.fitipower.com/dl/file/flXa6hIchVeu0W3K
Although it is in English, it seems to be only downloadable
from the Chinese part of that website.
For the JD9930 there can be a datasheet found at
https://e2e.ti.com/cfs-file/__key/communityserver-discussions-components-files/196/JD9930_2D00_0.7_2D00_JUN_2D00_2019.pdf
To simplify things, include the hwmon part directly which is only
one register read and there are not other functions besides
regulators in this chip.
Add a driver for the FP9931/JD9930 regulator. Implement handling of the PG
(power good), TS_EN (temperature sensor enable), and EN (enable regulators)
pins. Implement the pair of symmetric LDOs as a single regulator because
they share a single voltage set register. For simplicity, just add the
temperature sensor (depending on external NTC) directly.
Limitations:
- As these regulators are controlled together with the VCOM regulator via
the EN pin, some kind of management must be in place. As the enable op
is not called when the regulator is already enabled, simple refcounting
seems not to work to avoid clearing EN when one regulator is still
enabled. As these regulators are typically used together, this
limitation should not hurt hard, just provide the is_enabled op.
- As the VCOM step is quite odd (5V/255 steps), rounding is needed.
Due to some limitations in the regulator core, the max/min voltages in
the devicetree must match the idea of the driver how to round things
exactly.
- Night mode is not implemented, so only the FP9931 compatible is needed in
the driver, there is no REGULATOR_MODE_NIGHT and no clear definition in
the datasheet what it does, also the XON pin which seems to be an input
related to that night mode is not used.

This series adds support for three new MediaTek PMICs: MT6316, MT6363
and MT6373 and their variants - used in board designs featuring the
MediaTek MT8196 Chromebook SoC, or the MT6991 Dimensity 9400 Smartphone
SoC.
In particular, MT6316 is a regulator, but the MT6363 and MT6373 PMICs
are multi-function devices, as they have and expose multiple sub-devices;
moreover, some of those also contain an interrupt controller, managing
internal IPs interrupts: for those, a chained interrupt handler is
registered, which parent is the SPMI controller itself.
This series adds support for all of the MT6316 regulator variants and
for MT6363, MT6373 SPMI PMICs and their interrupt controller.
Add a driver for the regulators found on the MT6363 PMIC, fully
controlled by SPMI interface.
This PMIC regulates voltage with an input range of 2.6-5.0V, and
features 10 buck converters and 26 LDOs.

four step down DCDC (buck) converters.
In particular, this includes support for:
- MT6316(BP/VP): 2+2 Phase (Phase 1: buck1+2, Phase 2: buck3+4)
- MT6316(CP/HP/KP): 3+1 Phase (Phase 1: buck1+2+4, Phase 2: buck3)
- MT6316(DP/TP): 4+0 Phase (Single phase, buck1+2+3+4)
Please note that the set/clear registers for the enable bits are
not documented in the datasheet version that I used as reference,
but those are used in the downstream driver and I verified that
are actually working as expected.
Besides, it's also worth clearly mentioning that the MT6316 PMICs
voltage selector register uses a weird 9-bits Big Endian format,
for which a driver-private helper is provided.

Removals
- Remove the deprecated and unused mc13xxx_irq_ack() function from the MC13xxx RTC, input and

Add regulator for the 7" Raspberry Pi 720x1280 DSI panel based on ili9881.
This is the Raspberry Pi DSI Panel V2. The newer Raspberry Pi 5" and 7"
panels have a slightly different register map to the original one. Add a
new driver for this "regulator" chip, this time by exposing two GPIOs and
one PWM controller, both of which can be consumed by panel driver and
pwm-backlight respectively.

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 BD96801 "Scalable PMIC" is an automotive grade PMIC which can
scale to different applications by allowing chaining of PMICs. The PMIC
also supports various protection features which can be configured either
to fire IRQs - or to shut down power outputs when failure is detected.
The driver implements basic voltage control and sending error
notifications.
NOTE:
The driver does not support doing configuration which require the PMIC
to be in STBY state. The omitted feature set includes setting safety
limit values, changing LDO voltages and controlling enable state for
some regulators.
Also, the ERRB IRQ is not handled.

bit of the VBUS Control Register. This register is mapped in the reset
framework. The reset driver expose this register as regmap and instantiates
this driver. The consumer will use the regulator API to control the VBOUT
bit as the control need to be done in the atomic context.

The Qualcomm PM8008 is an I2C-controlled PMIC containing seven LDO
regulators.
The driver is based on a driver submitted by Satya Priya, but it has
been cleaned up and reworked to match the new devicetree binding which
no longer describes each regulator as a separate device.
This avoids describing internal details like register offsets in the
devicetree and allows for extending the implementation with features
like over-current protection without having to update the binding.
Specifically note that the regulator interrupts are shared between all
regulators.
Note that the secondary regmap is looked up by name and that if the
driver ever needs to be generalised to support regulators provided by
the primary regmap (I2C address) such information could be added to the
device-id table.
This also fixes the original implementation, which looked up regulators
by 'regulator-name' property rather than devicetree node name and which
prevented the regulators from being named to match board schematics.
