The second to last argument is clk_root (root of the clock), however the code called q6prm_request_lpass_clock() with clk_attr instead (copy-paste error). This effectively was passing value of 1 as root clock which worked on some of the SoCs (e.g. SM8450) but fails on others, depending on the ADSP. For example on SM8550 this "1" as root clock is not accepted and results in errors coming from ADSP.
