soc: qcom: spm: fix building with CONFIG_REGULATOR=n

2024-03-04T03:54:47+00:00

The newly added code causes a build failure when -Werror is set: drivers/soc/qcom/spm.c:388:12: error: 'spm_get_cpu' defined but not used [-Werror=unused-function] Remove the #ifdef and instead use an IS_ENABLED() check that lets the compiler perform dead code elimination instead of the preprocessor.

soc: qcom: spm: add support for voltage regulator

2024-02-16T17:30:57+00:00

The SPM / SAW2 device also provides a voltage regulator functionality with optional AVS (Adaptive Voltage Scaling) support. The exact register sequence and voltage ranges differs from device to device.

soc: qcom: spm: remove driver-internal structures from the driver API

2024-02-16T17:30:57+00:00

Move internal SPM driver structures to the driver itself, removing them from the public API. The CPUidle driver doesn't use them at all.

soc: qcom: Explicitly include correct DT includes

2023-07-14T21:05:06+00:00

The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.

soc: qcom: spm: Add CPU data for MSM8909

2022-07-18T23:05:07+00:00

Given the lack of public documentation for the SPM, the configuration data is taken without modification from Qualcomm's msm-3.10 release [1]. It is pretty much identical to the one for MSM8916, except that 0x3B is missing in the sequence for standalone power collapse for some reason.
