Add a regulator driver for the Spreadtrum/Unisoc SC2730 PMIC, used e.g. with the UMS512 and UMS9230 SoCs. This version of the driver is based on a downstream driver provided by Unisoc [1][2] and the existing SC2731 driver.

The platform was removed a few years ago, and the mfd driver is also gone now, so it is impossible to build or use it. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Link: https://patch.msgid.link/20260527193837.3436148-1-arnd@kernel.org Signed-off-by: Mark Brown <broonie@kernel.org>
Add support for the SG Micro SGM3804 Single Inductor Dual Output Buck/Boost Converter used to power LCD panels a provide positive and negative power rails with configurable voltage and active discharge function for each output. The SGM3804 is powered by the enable GPIO pins inputs and only supports I2C write messages. In order to add flexibility and simplify the driver, the regmap cache is enabled and populated with default values since we can't write registers when the 2 GPIOs are down.

Merge series from Andreas Kemnade <andreas@kemnade.info>: Add a driver for the TPS65185 regulator which provides the comparatively high voltages needed for electronic paper displays. Datasheet for the TPS65185 is at https://www.ti.com/lit/gpn/tps65185 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.

Merge series from cy_huang@richtek.com: This patch series add rt8092 regulator support.
RT8092 is a 3MHz 4A efficiency step-down converter with I2C control interface. It can support wide output range from 0.7 to 5.5V, based on the voltage bank selection.

Add support for the Maxim Integrated MAX77675 PMIC regulator. The MAX77675 is a compact, highly efficient SIMO (Single Inductor Multiple Output) power management IC that provides four programmable buck-boost switching regulators with only one inductor. It supports up to 700mA total output current and operates from a single-cell Li-ion battery. An integrated power-up sequencer and I2C interface allow flexible startup configuration and runtime control.

Merge series from Krzysztof Kozlowski <krzysztof.kozlowski@oss.qualcomm.com>: Use container_of_const(), which is preferred over container_of(), when the argument 'ptr' and returned pointer are already const, for better code safety and readability. Some drivers already have const everywhere, so container_of_const can be directly used. In few other drivers, the final pointer can be constified that way.
