regulator: pca9450: Add restart handler

2025-05-12T12:09:50Z

When restarting a CPU powered by the PCA9450 power management IC, it is beneficial to use the PCA9450 to power cycle the CPU and all its connected peripherals to start up in a known state. The PCA9450 features a cold start procedure initiated by an I2C command. Add a restart handler so that the PCA9450 is used to restart the CPU. The restart handler sends command 0x14 to the SW_RST register, initiating a cold reset (Power recycle all regulators except LDO1, LDO2 and CLK_32K_OUT) As the PCA9450 is a PMIC specific for the i.MX8M family CPU, the restart handler priority is set just slightly higher than imx2_wdt and the PSCI restart handler. This makes sure this restart handler takes precedence.

regulator: Add (devm_)of_regulator_get()

2025-02-24T15:26:08Z

The Rockchip power-domain controller also plans to make use of per-domain regulators similar to the MediaTek power-domain controller. Since existing DTs are missing the regulator information, the kernel should fallback to the automatically created dummy regulator if necessary. Thus the version without the _optional suffix is needed. The Rockchip driver plans to use the managed version, but to be consistent with existing code the unmanaged version is added at the same time.

regulator: Move OF_ API declarations/definitions outside CONFIG_REGULATOR

2025-01-06T13:04:34Z

Since these are hidden inside CONFIG_REGULATOR, building the consumer drivers without CONFIG_REGULATOR will result in the following build error: >> drivers/pci/pwrctrl/slot.c:39:15: error: implicit declaration of function 'of_regulator_bulk_get_all'; did you mean 'regulator_bulk_get'? [-Werror=implicit-function-declaration] 39 | ret = of_regulator_bulk_get_all(dev, dev_of_node(dev), | ^~~~~~~~~~~~~~~~~~~~~~~~~ | regulator_bulk_get cc1: some warnings being treated as errors This also removes the duplicated definitions that were possibly added to fix the build issues.
