* soc: qcom: Move power-domain drivers to the genpd dirUlf Hansson2023-07-141-992/+0
| | | | | | | | | | | | | 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: Hook up VDDMX as parent of SM6375 VDDGXKonrad Dybcio2023-03-151-0/+4
| | | | | | | | | | | | 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.

| | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | 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.
