From 2c0f07fe3ca57c8fb4ee179c9fb50d6eba75349e Mon Sep 17 00:00:00 2001 From: Kevin Wang Date: Mon, 3 Jun 2019 15:58:31 +0800 Subject: [PATCH] drm/amd/powerplay: add callback function of get_thermal_temperature_range 1. the thermal temperature is asic related data, move the code logic to xxx_ppt.c. 2. replace data structure PP_TemperatureRange with smu_temperature_range. 3. change temperature uint from temp*1000 to temp (temperature uint).
