Have you tried compiling this on PowerPC? devm_clk_get is only available
with CONFIG_CLKDEV_LOOKUP, I think on PowerPC this is not the case.

I've not, but I guess there will be an issue.  I'd say the fix here is
on the PowerPC side - it's not good to have to have Kconfig bodges for
things like this in individual drivers.  Ideally we'd add clkdev
support...

Or get rid of devm_clk_get()'s dependency on CLKDEV (which is in itself
silly.)

That'd work too, of course (providing everyone has been implementing
clk_put()).  Though getting everyone on the same page with the clock API
seems much more worthwhile if we can do it.

Why wouldn't clk_put() be implemented?  Drivers call it just like clk_get().

The devm*() stuff should just be a layer on top of clk_get()/clk_put() and
nothing more.

Lazy people who can't be bothered, especially on platforms that do
things like just return a pointer to a statically allocated clock or
never really expect their drivers to be unloaded.  Hopefully everyone
filled in the blank but I've just got a general pessimism about relying
on things like that.

Lazy people who can't be bothered, especially on platforms that do
things like just return a pointer to a statically allocated clock or
never really expect their drivers to be unloaded.  Hopefully everyone
filled in the blank but I've just got a general pessimism about relying
on things like that.
