I've tried to apply this on clk-next (currently v6.3-rc1) and also
linux-next (next-20230306), on both this patch doesn't apply:

Applying: clk: mediatek: mt8192: Move apmixedsys clock driver to its own file
error: patch failed: drivers/clk/mediatek/clk-mt8192.c:12
error: drivers/clk/mediatek/clk-mt8192.c: patch does not apply
Patch failed at 0047 clk: mediatek: mt8192: Move apmixedsys clock driver to its own file
hint: Use 'git am --show-current-patch=diff' to see the failed patch
When you have resolved this problem, run "git am --continue".
If you prefer to skip this patch, run "git am --skip" instead.
To restore the original branch and stop patching, run "git am --abort".
