The commit message should explain why this is needed rather than just
state what is being done. For example, something along the lines of
The three UFS reference clocks gcc_ufs_ref_clkref_clk,
gcc_ufs_card_clkref_clk and gcc_ufs_1_card_clkref_clk are all
sourced from CXO.
Update the clock driver to describe this.
should do.
