These patches adds support for SRM loading. By providing an interface to the
usermode

SRM has to be persistent and since the kernel cannot directly write to system
storage we need to provide an interface so that the usermode can do it for us


Bhawanpreet Lakha (5):
  drm/amd/display: Pass amdgpu_device instead of psp_context
  drm/amd/display: update psp interface header
  drm/amd/display: Add sysfs interface for set/get srm
  drm/amd/display: Load srm before enabling HDCP
  drm/amd/display: call psp set/get interfaces
