[PATCH 6/7] drm/amd/pp: Export load_firmware interface
Rex Zhu
Rex.Zhu at amd.com
Wed Sep 26 12:50:48 UTC 2018
Export this interface for the AMDGPU_FW_LOAD_SMU type.
gfx/sdma can request smu to load firmware.
Split the smu7/8_start_smu function into two functions
1. start_smu, used for load smu firmware in smu7/8 and
check smu firmware version.
2. request_smu_load_fw, used for load other ip's firmware
on smu7/8 and add firmware loading staus check.
