Here, you replaced hs_hclk_high_gate(in v9) with hs_hclk_high_src_rate,
but after my board test, I find that when hs_hclk_high_gate is turned
off, the mmc/sd and other high-speed subsystems can not work. So maybe
you should not change the hs_hclk_high_gate to hs_hclk_high_src_rate.

When I used clk_ignore_unused, I saw the log as follows, while the enable
and prepare count of hs_hclk_high_gate is zero. Here is the log:
