This cosmetic change is unrelated to the patch, please drop it.

Unless you plan to add support for other SoCs which have more than 2
channels, I think you can drop this - just add a OST_NUM_CHANNELS macro.

Instead of checking which clock you're manipulating here, just set a
different .recalc_rate to the two clocks.

Same here - set a different .set_rate() callback to the two clocks.

just { "ext" } will be fine, no need to specify the index, which is
zero anyway. Then you can drop the ost_clock_parent enum.

If that's a constant, just use the constant where
'ost->percpu_timer_channel' and 'ost->global_timer_channel' are used, I
think.

Don't call functions in variable declarations - they can be overlooked
easily.

return ret?

The 'ingenic_ost' variable is just a dirty workaround for the
sched_clock callback, which does not take any parameter. Avoid using it
here. Make ingenic_ost_probe() return a pointer to your ingenic_ost
instance (and a PTR_ERR() on error), and use that pointer for the rest.
