soc: qcom: Move power-domain drivers to the genpd dir

2023-07-14T08:40:18+00:00

To simplify with maintenance let's move the qcom power-domain drivers to the new genpd directory. Going forward, patches are intended to be managed through a separate git tree, according to MAINTAINERS.

soc: qcom: rpmpd: use correct __le32 type

2023-05-25T03:00:58+00:00

Use cpu_to_le32 to cast constants to __le32 before comparing them with __le32 type pd->key. This fixes the following sparse warnings: drivers/soc/qcom/rpmpd.c:895:31: sparse: warning: restricted __le32 degrades to integer drivers/soc/qcom/rpmpd.c:896:15: sparse: warning: restricted __le32 degrades to integer Signed-off-by: Min-Hua Chen Reviewed-by: Konrad Dybcio Signed-off-by: Bjorn Andersson Link: https://lore.kernel.org/r/20230522160757.284165-1-minhuadotchen@gmail.com

soc: qcom: rpmpd: Remove useless comments

2023-03-15T22:40:28+00:00

It goes without saying that socname_rpmpds[] is the array of the RPM power domains associated with socname. Remove these comments. Signed-off-by: Konrad Dybcio Signed-off-by: Bjorn Andersson Link: https://lore.kernel.org/r/20230313-topic-rpmpd-v3-10-06a4f448ff90@linaro.org

soc: qcom: rpmpd: Hook up VDDMX as parent of SM6375 VDDGX

2023-03-15T22:40:28+00:00

The GPU core clock requires that both VDDGX and VDDMX domains are scaled at the same rate at the same time (well, MX just before GX but you get the idea). Set MX as parent of GX to take care of that.

soc: qcom: rpmpd: Add parent PD support

2023-03-15T22:40:27+00:00

In some cases (like with the GPU core clock on GMU-less SoCs) it's required that we scale more than one voltage domain. This can be achieved by linking them in a parent-child relationship. Add support for specifying a parent PD, similarly to what has been done in the RPMhPD driver.

soc: qcom: rpmpd: Make bindings assignments consistent

2023-03-15T22:40:27+00:00

Currently the whitespace between [DT_BINDING] = &struct is all over the place.. some SoC structs have a space, others have a tab, others have N tabs.. Make that a single tab for everybody to keep things coherent.

soc: qcom: rpmpd: Improve the naming

2023-03-15T22:40:27+00:00

Now that we aren't bound by the preprocessor macros, improve the naming to be a bit less preprocessor-y and touch up some rpmpd.pd.name fields while at it. Signed-off-by: Konrad Dybcio Signed-off-by: Bjorn Andersson Link: https://lore.kernel.org/r/20230313-topic-rpmpd-v3-6-06a4f448ff90@linaro.org

soc: qcom: rpmpd: Expand struct definition macros

Expand the struct definition macros to make things easier to see and maintain. Now that the macros are unnecessary, remove them. Signed-off-by: Konrad Dybcio Signed-off-by: Bjorn Andersson Link: https://lore.kernel.org/r/20230313-topic-rpmpd-v3-5-06a4f448ff90@linaro.org

soc: qcom: rpmpd: Remove vdd* from struct names

2023-03-15T22:40:27+00:00

It's rather obvious by the characteristic of these resources that they correspond to some voltage lines governed by RPM. Remove the "vdd" unnecessary prefix from them.

2023-03-15T22:40:27+00:00

Up until now, we had 2 separate entries for VDD_LPI[CM]X and VDD_LPI_[CM]X which both pointed to the same RPM resource. Fix it. Signed-off-by: Konrad Dybcio Signed-off-by: Bjorn Andersson Link: https://lore.kernel.org/r/20230313-topic-rpmpd-v3-3-06a4f448ff90@linaro.org
