+Subject: [PATCH 3032/4256] drm/amd/display: refactor dump_clk_registers
+
+[why]
+for 2 purposes:
+
+1. get raw register value dumped on the log, which will make it easier
+to talk to other team who only knows about the register
+
+2. enable other HW to be able to use the same interface as raven to log
+clock register data
