2022-10-26power: regulator: fix autoset error handlingJohn Keeping1-1/+7
If a regulator does not support .set_suspend_enable or .set_suspend_value then ret is set to ENOSYS early in the function. The most serious impact of this is that when no automatic setting of voltage is needed then the final regulator_set_enable() is skipped because ret has not been cleared. It seems that the error handling for regulator_set_suspend_value() is also wrong as if this succeeds then the normal boot-on checks are still required, and again ENOSYS needs special treatment here.

Since both pm8916.c and pm8916_gpio.c are already supporting multiple Qcom SoCs, it makes sense to rename these drivers to pmic_qcom.c and qcom_pmic_gpio.c respectively. Also, these driver can be extended to support additional functionality if required for other Qcom SoCs.

In order to have the possibility to configure the regulators at system startup through DM support, all LDOs and bucks must be able to be changeable. Currently there is a limitation to change the values when the output is enabled. Since the driver is based on the ROHM BD71837 and a comment that describes a limitation about switching while the output is enabled can also be found there, the limitation probably comes from this type.

2022-06-29rockchip: Add option to prevent booting on power plug-inChris Morgan1-0/+34
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.

2022-06-28pmic: pca9450: Add optional SD_VSEL GPIO for LDO5Frieder Schrempf1-0/+27
LDO5 has two separate control registers. LDO5CTRL_L is used if the input signal SD_VSEL is low and LDO5CTRL_H if it is high. The current driver implementation only uses LDO5CTRL_H. To make this work on boards that have SD_VSEL connected to a GPIO, we add support for specifying an optional GPIO and setting it to high at probe time. In the future we might also want to add support for boards that have SD_VSEL set to a fixed low level. In this case we need to change the driver to be able to use the LDO5CTRL_L register.
