This conflicts with [1], which you sent just before.

If that patch goes in first, I guess this new entry should gain
", MSTOP(PERI_CPU, BIT(13))", just like the entry for ia55_clk?

Sorry for that, I intended to adapt the one that will have ended up last in
your tree.

That's right.

As the MSTOP support is on hold, I will queue this in renesas-clk-for-v6.8.
