My working branch : https://github.com/clementperon/linux/commits/panfrost_devfreq Two strange things I observe: - After 30sec the regulator is released by OPP ??? [ 33.757627] vdd-gpu: disabling Introduce the regulator support in this commit: https://github.com/clementperon/linux/commit/be310c37b82010e293b7f129ccdcb711a2abb2ce - The Cooling map is not probe correctly : [ 2.545756] panfrost 1800000.gpu: [drm:panfrost_devfreq_init [panfrost]] Failed to register cooling device Introduce in this commit : https://github.com/clementperon/linux/commit/0252c38fd55ad78366ac4b1714e285c88db34557 Do you have an hint about what I'm missing ?
