This round of updates contains a fair amount of new device support, a couple of fixes and
some refactoring. The most notable additions include new drivers for Loongson's Security
Engine, RNG and TPM, new drivers for TI's TPS6594 Power Button and BQ257xx Charger ICs.
The rest of the set provides a return value check fix and a refactoring to use a more modern
GPIO API for the VEXPRESS sysreg driver, the removal of a deprecated IRQ ACK function from the
MC13xxx RTC driver and a new DT binding for the aforementioned TI BQ257xx charger.
New Support & Features
- Add a suite of drivers for the Loongson Security Engine, including the core controller, a
Random Number Generator (RNG) and Trusted Platform Module (TPM) support.
- Introduce support for the TI TPS6594 PMIC's power button, including the input driver, MFD
cell registration, and a system power-off handler.
- Add comprehensive support for the TI BQ257xx series of charger ICs, including the core MFD
driver and a power supply driver for the charger functionality.
Improvements & Fixes
- Check the return value of devm_gpiochip_add_data() in the VEXPRESS sysreg driver to prevent
potential silent failures.
Cleanups & Refactoring
- Add a MAINTAINERS entry for the new Loongson Security Engine drivers.
- Convert the VEXPRESS sysreg driver to use the modern generic GPIO chip API.
Removals
- Remove the deprecated and unused mc13xxx_irq_ack() function from the MC13xxx RTC, input and
touchscreen drivers.
Device Tree Bindings Updates
- Add device tree bindings for the TI BQ25703A charger.

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"

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

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.

As per the RZ/G2L HW manual, VBUSEN can be controlled by the VBOUT
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.

D1 contains two pairs of LDOs, "analog" LDOs and "system" LDOs. They are
similar and can share a driver, but only the system LDOs have a DT

The system LDOs have a single linear range. The voltage step is not an
integer, so a custom .list_voltage is needed to get the rounding right.

LLVM moved their issue tracker from their own Bugzilla instance to GitHub
issues. While all of the links are still valid, they may not necessarily
show the most up to date information around the issues, as all updates
will occur on GitHub, not Bugzilla.
Another complication is that the Bugzilla issue number is not always the
same as the GitHub issue number. Thankfully, LLVM maintains this mapping
through two shortlinks:
https://llvm.org/bz<num> -> https://bugs.llvm.org/show_bug.cgi?id=<num>
https://llvm.org/pr<num> -> https://github.com/llvm/llvm-project/issues/<mapped_num>
Switch all "https://bugs.llvm.org/show_bug.cgi?id=<num>" links to the
"https://llvm.org/pr<num>" shortlink so that the links show the most up to
date information. Each migrated issue links back to the Bugzilla entry,
so there should be no loss of fidelity of information here.
