Subject[PATCH v3 00/14] Add regulator devfreq support to Panfrost

This serie cleans and adds regulator support to Panfrost devfreq.
This is mostly based on comment for the freshly introduced lima

We need to add regulator support because on Allwinner the GPU OPP
table defines both frequencies and voltages.

First patches [01-07] should not change the actual behavior
and introduce a proper panfrost_devfreq struct.


Changes since v2:
- Collect Alyssa Rosenzweig reviewed-by tags
- Fix opp_set_regulator before adding opp_table (introduce in v2)
- Call err_fini in case opp_add_table failed

Changes since v1:
- Collect Steven Price reviewed-by tags
- Fix spinlock comment
- Drop OPP clock-name path
- Drop device_property_test patch
- Add rename error labels patch

Clément Péron (14):
drm/panfrost: avoid static declaration
drm/panfrost: clean headers in devfreq
drm/panfrost: don't use pfdevfreq.busy_count to know if hw is idle
drm/panfrost: introduce panfrost_devfreq struct
drm/panfrost: use spinlock instead of atomic
drm/panfrost: properly handle error in probe
drm/panfrost: rename error labels in device_init
drm/panfrost: move devfreq_init()/fini() in device
drm/panfrost: dynamically alloc regulators
drm/panfrost: add regulators to devfreq
arm64: defconfig: Enable devfreq cooling device
arm64: dts: allwinner: h6: Add cooling map for GPU
[DO NOT MERGE] arm64: dts: allwinner: h6: Add GPU OPP table
[DO NOT MERGE] arm64: dts: allwinner: force GPU regulator to be always
