From: tiancyin <[email protected]> [why] The uclk dpm feature is not supported by some certain navi10 board like 18202, while supported by some board like 18201. It causes modprobe failure on 18202 board.
[how] Disabled this feature by default, it can be enabled by module parameter uclk_dpm_support=1.
