I'm printing all but a few writel's but I'm not seeing anything when the
regulators are being set up... Something to investigate.

Even with that "fixed" [or rather hacked around, since the syntax of
drivers/clk/qcom/gcc-msm8998.c remains nebulous, even after staring
at it, literally, for hours] the UFSHC refuses to functio

I thought I had found the problem:
"clk_set_rate: ufs_unipro_core_clk_src" was not occurring.
