Title:
  AMD HAINAN (Radeon R5 M330) Clock frequency is 750MHz while it is
  supposed to be 1030MHz

Status in Linux:
  Unknown
Status in linux package in Ubuntu:
  Confirmed

Bug description:
  Kernel source: /drivers/gpu/drm/radeon/si_dpm.c line 2985:

                          max_sclk = 75000;

  instead of

                          max_sclk = 103000;

  Why is that? I changed it and rebuilt the kernel, and I can say that
  there are absolutely no issues when using the 1030MHz clock, which is
  what it is supposed to be.
