[PATCH v1 0/4] powercap: dtpm: Use generic hierarchy helpers and add RK3588 support

[Daniel Lezcano]

This series builds on top of the previously submitted powercap series
introducing the generic powercap hierarchy infrastructure.

DTPM currently implements its own hierarchy creation logic to walk a
platform-provided description, create the corresponding DTPM zones and
tear them down. With the generic powercap hierarchy infrastructure in
place, this logic can be shared at the powercap core level.

Convert DTPM to use the generic powercap hierarchy helpers. The platform
hierarchy is duplicated before use and powercap_hierarchy_create() and
powercap_hierarchy_destroy() take care of its lifetime and traversal.
DTPM provides the callbacks responsible for creating and destroying the
DTPM instance associated with each powercap node. The CPU and devfreq
backends are adjusted accordingly.

As a preparation for this conversion, simplify the existing RK3399
description. The CPU backend creates one DTPM zone per cpufreq policy,
so describing every CPU belonging to the same policy results in
duplicate zones. Keep only one CPU node for each RK3399 cpufreq policy.

The Rockchip virtual node descriptor is then made SoC-independent so it
can be reused by other Rockchip platforms.

Finally, add an RK3588 hierarchy. The RK3588 has three cpufreq policies,
represented by cpu@0, cpu@400 and cpu@600. These three CPU domains are
grouped below a virtual package node:

rk3588
  `-- package
    |-- cpu0-cpufreq
    |-- cpu4-cpufreq
    `-- cpu6-cpufreq
