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 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 .../dts/allwinner/sun50i-h6-beelink-gs1.dts | 1 + arch/arm64/boot/dts/allwinner/sun50i-h6.dtsi | 102 ++++++++++ arch/arm64/configs/defconfig | 1 + drivers/gpu/drm/panfrost/panfrost_devfreq.c | 175 ++++++++++++------ drivers/gpu/drm/panfrost/panfrost_devfreq.h | 30 ++- drivers/gpu/drm/panfrost/panfrost_device.c | 61 +++--- drivers/gpu/drm/panfrost/panfrost_device.h | 14 +- drivers/gpu/drm/panfrost/panfrost_drv.c | 15 +- drivers/gpu/drm/panfrost/panfrost_job.c | 10 +- 9 files changed, 296 insertions(+), 113 deletions(-) -- 2.25.1
