2023-01-31pmic: pca9450: Make warm reset on WDOG_B assertionMarek Vasut1-0/+4
The default configuration of the PMIC behavior makes the PMIC power cycle most regulators on WDOG_B assertion. This power cycling causes the memory contents of OCRAM to be lost. Some systems neeeds some memory that survives reset and reboot, therefore this patch is created.

2022-06-29rockchip: Add option to prevent booting on power plug-inChris Morgan1-0/+3
For Rockchip boards with the all rk8xx series PMICs (excluding the rk808), it is sometimes desirable to not boot whenever the device is plugged in. An example would be for the Odroid Go Advance. This provides a configurable option to check the PMIC says it was powered because of a plug-in event. If the value is 1 and this option is selected, the device shuts down shortly after printing a message to console stating the reason why it's shutting down. Powering up the board with the power button is not affected. This patch parallels the work done in the following patch series: https://lore.kernel.org/u-boot/20220121133732.2397273-1-andre.przywara@arm.com/ Signed-off-by: Chris Morgan <macromorgan@hotmail.com> Reviewed-by: Jaehoon Chung <jh80.chung@samsung.com>

2022-06-17stm32mp: stpmic1: remove the debug unit request by debuggerPatrick Delaunay1-3/+0
Depending on backup register value, U-Boot SPL maintains the debug unit powered-on for debugging purpose; only BUCK1 is required for powering the debug unit, so revert the setting for all the other power lanes, except BUCK3 that has to be always on. To be functional this patch requires a modification in the debugger ,openocd for example, to update the STM32MP15 backup register when it is required to debug SPL after reset. After deeper analysis this behavior will be never supported in tools so the associated code, will be never used and the associated code can be removed.

2021-07-14power: pmic: Add driver for ST-Ericsson AB8500 via PRCMUStephan Gerhold1-0/+125
All devices based on ST-Ericsson Ux500 use a PMIC similar to AB8500 (Analog Baseband). There is AB8500, AB8505, AB9540 and AB8540 although in practice only AB8500 and AB8505 are relevant since the platforms with AB9540 and AB8540 were cancelled and never used in production. In general, the AB8500 PMIC uses I2C as control interface, where the different register banks are represented as separate I2C devices. However, in practice AB8500 is always connected to a special I2C bus on the DB8500 SoC that is controlled by the power/reset/clock management unit (PRCMU) firmware. Add a simple driver that allows reading/writing registers of the AB8500 PMIC. The driver directly accesses registers from the PRCMU parent device (represented by syscon in U-Boot). Abstracting it further (e.g. with the i2c uclass) would not provide any advantage because the PRCMU I2C bus is always just connected to AB8500 and vice-versa. The ab8500.h header is mostly taken as-is from Linux (with some minor adjustments) to allow using similar code in both Linux and U-Boot.

BD71837 and BD71847 is PMIC intended for powering single-core, dual-core, and quad-core SoC’s such as NXP-i.MX 8M. BD71847 is used for example on NXP imx8mm EVK. Add regulator driver for ROHM BD71837 and BD71847 PMICs. BD71837 contains 8 bucks and 7 LDOS. BD71847 is reduced version containing 6 bucks and 6 LDOs. Voltages for DVS bucks (1-4 on BD71837, 1 and 2 on BD71847) can be adjusted when regulators are enabled. For other bucks and LDOs we may have over- or undershooting if voltage is adjusted when regulator is enabled. Thus this is prevented by default. BD718x7 has a quirk which may leave power output disabled after reset if enable/disable state was controlled by SW. Thus the SW control is only allowed for BD71837 bucks 3 and 4 by default. The impact of this limitation must be evaluated board-by board and restrictions may need to be modified.
