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.

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.

power: regulator: scmi: support SCMI multi-channel

2022-06-23T17:12:55Z

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

firmware: scmi: prepare scmi uclass API to multi-channel

2022-06-23T17:12:55Z

Changes SCMI driver API function devm_scmi_process_msg() to add an SCMI channel reference argument for when SCMI agent supports SCMI protocol specific channels. First argument of devm_scmi_process_msg() is also change to point to the caller SCMI protocol device rather than its parent device (the SCMI agent device). The argument is a pointer to opaque struct scmi_channel known from the SCMI transport drivers. It is currently unused and caller a pass NULL value. A later change will enable such support once SCMI protocol drivers have means to get the channel reference during initialization.
