regulator: bd718x7: Fix voltages scaled by resistor divider

2025-10-30T11:30:23Z

The .min_sel and .max_sel fields remained uninitialized in the new linear_range, causing an error further down the line. Copy the old values of these fields to the new one as they represent the range of register values, which does not change.

2025-10-01T19:04:12Z

Pull MFD updates from Lee Jones: "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" * tag 'mfd-next-6.18' of git://git.kernel.org/pub/scm/linux/kernel/git/lee/mfd: (69 commits) mfd: simple-mfd-i2c: Add compatible string for LX2160ARDB mfd: simple-mfd-i2c: Keep compatible strings in alphabetical order dt-bindings: mfd: twl: Add missing sub-nodes for TWL4030 & TWL603x dt-bindings: watchdog: Add SMARC-sAM67 support dt-bindings: mfd: tps6594: Allow gpio-line-names mfd: intel-lpss: Add Intel Wildcat Lake LPSS PCI IDs mfd: 88pm886: Add GPADC cell mfd: vexpress-sysreg: Use more common syntax for compound literals mfd: rz-mtu3: Fix MTU5 NFCR register offset mfd: max77705: Setup the core driver as an interrupt controller mfd: cs42l43: Remove IRQ masking in suspend mfd: cs42l43: Move IRQ enable/disable to encompass force suspend mfd: ls2kbmc: Add Loongson-2K BMC reset function support mfd: ls2kbmc: Introduce Loongson-2K BMC core driver mfd: bd71828, bd71815: Prepare for power-supply support dt-bindings: mfd: aspeed: Add AST2700 SCU compatibles dt-bindings: mfd: Convert aspeed,ast2400-p2a-ctrl to DT schema dt-bindings: mfd: fsl,mc13xxx: Add buttons node dt-bindings: mfd: fsl,mc13xxx: Convert txt to DT schema mfd: macsmc: Add "apple,t8103-smc" compatible ...

regulator: Fix MAX77838 selection

2025-09-17T17:46:21Z

The current entry for the MAX77838 regulator is unselectable (as it depended on a non-user-selectable config - REGMAP_I2C). Fix this by making it select the config, and not depending on it.

regulator: spacemit: support SpacemiT P1 regulators

2025-09-16T13:34:44Z

Add support for the regulators found in the SpacemiT P1 PMIC. This PMIC provides 6 buck converters and 12 LDO regulators. The PMIC is implemented as a multi-function device. These regulators are probed based on this driver being named in a MFD cell in the simple MFD I2C driver.
