Subject: [PATCH v2 00/14] Add regulator devfreq support to Panfrost

Hi,

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

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.

Regards,
Clément

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
