dtpm/soc/rk3399: Add the ability to unload the module

2022-02-23T18:46:29Z

The dtpm hierarchy can now be removed with the dtpm_destroy_hierarchy() function. Add the module_exit() callback so the module can be unloaded by removing the previously created hierarchy.

rockchip/soc/drivers: Add DTPM description for rk3399

2022-02-04T16:38:09Z

The DTPM framework does support now the hierarchy description. The platform specific code can call the hierarchy creation function with an array of struct dtpm_node pointing to their parent. This patch provides a description of the big / Little CPUs and the GPU and tie them together under a virtual 'package' name. Only rk3399 is described now. The description could be extended in the future with the memory controller with devfreq. The description is always a module and it describes the soft dependencies. The userspace has to load the softdeps module in the right order.
