Not sure where you're seeing this?
This is from my msm-4.19 tree:
gcc_ufs_phy_axi_clk_src:
.rate_max = (unsigned long[VDD_NUM]) { [VDD_LOWER] = 50000000,
gcc_ufs_phy_unipro_core_clk_src:
.rate_max = (unsigned long[VDD_NUM]) { [VDD_LOWER] = 37500000,
gcc_ufs_phy_ice_core_clk_src:
.rate_max = (unsigned long[VDD_NUM]) { [VDD_LOWER] = 75000000,
[VDD_LOWER] = RPMH_REGULATOR_LEVEL_LOW_SVS,
My intepretation for this is we need low_svs?
Regards
Luca
