Merge tag 'thead-clk-for-v6.17-p2' of git://git.kernel.org/pub/scm/linux/kernel/git/fustini/linux into clk-thead
Pull one more T-HEAD clk driver update from Drew Fustini:
Yao Zi has fixed an issue where the c910 mux clk could end up as an
orphan in CCF when the bootloader reparents it to the c910-i0 mux clk.
The solution is to refactor the handling of mux clocks by embedding a
clk_mux structure directly in ccu_mux. This allows the mux clocks to be
registered with devm_clk_hw_register() without allocating any new clk_hw
pointer which solves the orphan issue.
This change has been tested in linux-next. The LPi4a still boots okay
without clk_ignore_unused and peripherals like serial, emmc and ethernet
are functional. The file /sys/kernel/debug/clk/c910/clk_possible_parents
now correctly outputs: "c910-i0 cpu-pll1"
