Aha I get it, then it looks good...

Is that an Ack for the patch?

Yep! FWIW
Acked-by: Linus Walleij <redacted>

I think there's one change I'd like, which is to change "busck" to
"apb_pclk" to make it clear what it's referring to.

Looks good.

Also, is there any chance you can convert your platform(s) over to use
it before I merge this patch?

I can take a round over the U300 within a few days, Rabin can
maybe look at the U8500.

In the U300 (maybe the U8500 as well, I don't know OTOH) the
APB pclk and e.g. SSPCLK is simply just wired together and
connected to the same clock terminal. This means that currently
the PCLK is toggled on/off in unison with the SSPCLK all the time
already, and it's working.

Since that works, it means that we can likely insert
amba_bus_clk_[disable|enable] at the same sites that we have
this in the current code for the external clocks at the same time,
atleast for pl011, pl022 and pl180.
