power: regulator: Add a driver for the AXP USB power supply

2023-04-28T00:29:40Z

This driver reports the presence/absence of voltage on the PMIC's USB VBUS pin. This information is used by the USB PHY driver. The corresponding Linux driver uses the power supply class, which does not exist in U-Boot. UCLASS_REGULATOR seems to be the closest match.

power: pmic: Add NXP PCA9451A PMIC support

2023-03-29T22:45:39Z

PCA9451A uses similar BUCKs and LDO regulators as PCA9450B/C but has LDO2 and LDO3 removed. So reuse pca9450 PMIC and regulator driver and add new type for PCA9451A. Signed-off-by: Ye Li Reviewed-by: Marek Vasut

power: regulator: Add a driver for AXP PMIC regulators

2023-01-23T01:18:31Z

This driver handles most voltage regulators found in X-Powers AXP PMICs. It is based on, and intended to replace, the regulator driver in TF-A. AXP PMIC regulators can be divided into 6 categories: - Switches without voltage control => fully supported. - Single linear range => fully supported. - Two linear ranges, "step" and "2 * step" => fully supported. - Two linear ranges, "step" and "5 * step" => only the first range is supported. No boards are known to use the second range. - Non-linear voltage values => fully supported. - LDOs shared with GPIO pins => not supported.

power: regulator: fix autoset error handling

2022-10-26T02:47:12Z

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.

power: regulator: Remove i2c header from gpio regulator

pmic: pca9450: permit config on all bucks and LDOs

2022-07-27T04:04:34Z

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.

spl: Ensure all SPL symbols in Kconfig have some SPL dependency

2022-07-07T13:29:08Z

Tighten up symbol dependencies in a number of places. Ensure that a SPL specific option has at least a direct dependency on SPL. In places where it's clear that we depend on something more specific, use that dependency instead. This means in a very small number of places we can drop redundant dependencies.

Update SCMI regulator controller driver to get its assigned SCMI channel during initialization. This change allows SCMI voltage domain protocol to use a dedicated channel when defined in the DT. The reference is saved in SCMI regulator controller driver private data. Cc: Jaehoon Chung Signed-off-by: Etienne Carriere Reviewed-by: Jaehoon Chung
