git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator Pull regulator updates from Mark Brown: "There's one API update here, a new API factoring out a common pattern for reference voltage supplies. These are supplies used as a reference by analogue circuits where the consumer requests and enables the supply, reads the voltage to calibrate the user and then never touches it again. This is factored out into a single operation which just returns the voltage and uses devm_ to manage the request and enable portion. Otherwise this has been a very quiet release, we've got some new device support, some small fixes, housekeeping and cleanup work but nothing substantial. There's also some non-regulator changes in here, a number of users for the new reference voltage API were merged along with it and some MFD changes were pulled in as dependencies for new driver work. Highlights: - Add a new API for single operation handling of reference voltages - Support for Allwinner AXP717 and D1, and NXP PCA9561A" * tag 'regulator-v6.10' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator: (33 commits) regulator: sun20i: Add Allwinner D1 LDOs driver regulator: dt-bindings: Add Allwinner D1 system LDOs regulator: Mention regulator id in error message about dummy supplies staging: iio: impedance-analyzer: ad5933: Use devm_regulator_get_enable_read_voltage() iio: frequency: admv1013: Use devm_regulator_get_enable_read_voltage() iio: addac: ad74115: Use devm_regulator_get_enable_read_voltage() hwmon: (adc128d818) simplify final return in probe regulator: devres: fix devm_regulator_get_enable_read_voltage() return hwmon: (da9052) Use devm_regulator_get_enable_read_voltage() hwmon: (adc128d818) Use devm_regulator_get_enable_read_voltage() regulator: devres: add API for reference voltage supplies regulator: rtq2208: Fix LDO discharge register and add vsel setting regulator: dt-bindings: fixed-regulator: Add a preferred node name regulator: axp20x: add support for the AXP717 mfd: axp20x: Add support for AXP717 PMIC dt-bindings: mfd: x-powers,axp152: Document AXP717 regulator: axp20x: fix typo-ed identifier dt-bindings: regulator: qcom,usb-vbus-regulator: Add PM7250B compatible regulator: pca9450: add pca9451a support regulator: dt-bindings: pca9450: add pca9451a support ...

access-controllers is an optional property that allows a peripheral to refer to one or more domain access controller(s). Description of this property is added to all peripheral binding files of the peripheral under the STM32 firewall controller. It allows an accurate representation of the hardware, where various peripherals are connected to a firewall bus. The firewall can then check the peripheral accesses before allowing its device to probe.

2023-11-13regulator: add under-voltage support (part 2)Mark Brown2-0/+15
Merge series from Oleksij Rempel <o.rempel@pengutronix.de>: This series add under-voltage and emergency shutdown for system critical regulators
2023-11-13regulator: dt-bindings: Add 'regulator-uv-less-critical-window-ms' propertyOleksij Rempel1-0/+8
Introduces a new devicetree property to specifies the time window (in milliseconds) following a critical under-voltage (UV) event during which less critical actions can be safely carried out by the system. Less Critical Actions: - Logging the under-voltage event for later analysis. - Saving less critical data that may be useful for diagnosing issues or for audit purposes. More Critical Actions (post the less critical window): - Initiating procedures to properly shutdown hardware to prevent damage. The 'regulator-uv-less-critical-window-ms' property is crucial for conveying board-specific hardware characteristics, not for enforcing a certain policy. The time window represented by this property is derived from the physical attributes of the hardware like the capacity of on-board capacitors, the power consumption of the components, and the time needed to safely shut down hardware to prevent damage. These attributes can significantly vary between different boards, making it a board-specific property rather than a policy directive. By providing a precise representation of the time available for less critical actions post an under-voltage event, this property enables the kernel to make informed decisions on action prioritization, ensuring that essential preventative measures are taken to avoid hardware damage while also allowing for data capture and analysis.

To cater to such use cases, this patch extends the fixed regulator binding to support the 'system-critical-regulator' property. This property signifies that the fixed-regulator is vital for system stability.

2023-10-02regulator: dt-bindings: mt6358: Add MT6366 PMICZhiyong Tao1-29/+120
The MediaTek MT6366 PMIC is similar to the MT6358 PMIC. It is designed to be paired with the MediaTek MT8186 SoC. It has 9 buck regulators and 29 LDO regulators, not counting ones that feed internally and basically have no controls. The regulators are named after their intended usage for the SoC and system design, thus not named generically as ldoX or dcdcX, but as vcn33 or vgpu. The differences compared to the MT6358 are minimal: - Regulators removed: VCAMA1, VCAMA2, VCAMD, VCAMIO, VLDO28 - Regulators added: VM18, VMDDR, VSRAM_CORE Both PMIC models contain a chip ID register at the same address that can be used to differentiate the actual model. Thus, even though the MT6366 is not fully backward compatible with the MT6358, it still falls back on the MT6358 compatible string. It is up to the implementation to use the chip ID register as a probing mechanism. Update the MT6358 regulator binding and add entries for all the MT6366's regulators and their supplies. The regulator node names follow a cleaned up style without type prefixes and with underscores replaced with hyphens.

2023-10-02regulator: dt-bindings: mt6358: Add regulator-allowed-modes propertyChen-Yu Tsai1-0/+27
The MT6358 PMIC allows changing operating modes for the buck regulators, but not the LDOs. Existing device trees and the Linux implementation already utilize this through the standard regulator-allowed-modes property. The values currently used in existing device trees are simply raw numbers. The values in the Linux driver are matching numbers defined with macros denoting the two supported modes. Turns out these two modes are common across parts of the larger MT63xx PMIC family. The MT6397 regulator binding already has macros for the two modes, with matching numbers. Codify the supported values for regulator-allowed-modes for the MT6358 in the device tree binding: 0 and 1 are supported for buck regulators, and the property should not be present for LDO regulators. Users should use the dt-bindings/regulator/mediatek,mt6397-regulator.h header for the macros, instead of using raw numbers.

Convert this from the old style text based binding to the new DT schema style. This will make adding the MT6366 portion easier. The examples have been trimmed down considerably, and the remaining entries now match what is seen in actual device trees, minus some properties that aren't covered by the bindings yet, or don't make sense on their own. The original submitter seems to have left MediaTek, so instead the submitter and maintainer for the MT6366 binding is listed as the maintainer here.
