2022-01-31soc: qcom: rpmpd: Check for null return of devm_kcallocJiasheng Jiang1-0/+3
Because of the possible failure of the allocation, data->domains might be NULL pointer and will cause the dereference of the NULL pointer later. Therefore, it might be better to check it and directly return -ENOMEM without releasing data manually if fails, because the comment of the devm_kmalloc() says "Memory allocated with this function is automatically freed on driver detach.".

2021-01-25drivers: soc: qcom: rpmpd: Add msm8994 RPM Power DomainsKonrad Dybcio1-0/+28
MSM8994 uses similar to MSM8996, legacy-style voltage control, but does not include a VDD_SC_CX line. This setup is also correct for MSM8992. Do note that there exist some boards that use a tertiary PMIC (most likely pm8004), where SMPB on VDDGFX becomes SMPC. I cannot test this configuration though.

2020-10-26soc: qcom: rpmpd: Rename MAX_8996_RPMPD_STATE to MAX_CORNER_RPMPD_STATEStephan Gerhold1-2/+2
Older SoCs like MSM8916, MSM8939, MSM8974, MSM8996, ... use "voltage corners" instead of "voltage levels". It seems like they all use exactly the same set of corner values, a value from 0-6 where 6 is the maximum corner (super turbo). In preparation to add the power domains for MSM8916, rename MAX_8996_RPMPD_STATE to MAX_CORNER_RPMPD_STATE to make it clear that this is the max_state to be used for all SoCs using corners. - Signed-off-by: Stephan Gerhold <stephan@gerhold.net> Link: https://lore.kernel.org/r/20200916104135.25085-2-stephan@gerhold.net Signed-off-by: Bjorn Andersson <bjorn.andersson@linaro.org>

2020-04-14soc: qcom: rpmpd: Allow RPMPD driver to be loaded as a moduleJohn Stultz1-0/+5
This patch allow the rpmpd driver to be loaded as a permenent module. Meaning it can be loaded from a module, but then cannot be unloaded. Ideally, it would include a remove hook and related logic, but apparently the genpd code isn't able to track usage and cleaning things up? (See: https://lkml.org/lkml/2019/1/24/38) So making it a permenent module at least improves things slightly over requiring it to be a built in driver.

2019-01-22soc: qcom: rpmpd: Add a Power domain driver to model cornersRajendra Nayak1-0/+282
The Power domains for corners just pass the performance state set by the consumers to the RPM (Remote Power manager) which then takes care of setting the appropriate voltage on the corresponding rails to meet the performance needs. We add all power domain data needed on msm8996 here. This driver can easily be extended by adding data for other qualcomm SoCs as well.
