I checked the HW doc and yes in both IPQ5018 and IPQ5332 CONFIG_CTL_U
register is not implemented. I see offset of CONFIG_CTL_U register is
removed in the change[1] by Gabor.
Given that, should we also drop the pll_has_64bit_config() if block from
clk_stromer_pll_configure function?
Nevertheless, for this patch
