Move the dmtimer driver out of plat-omap to clocksource.
So that non-omap devices also could use this.
No Code changes done to the driver file.

Huh. I think It might be better if you add smth. like
struct omap_dm_timer *dm_timer = of_omap_dm_timer_get(parent_np, "ti,timers", idx);
struct omap_dm_timer_ops *pdata = omap_dm_timer_get_ops(dm_timer);
so all DT and platdata implementation details will be hidden.

Grygorii,
This driver is already fetching:
omap->dm_timer_pdev = of_find_device_by_node(timer);
It stores dm_timer_pdev in struct pwm_omap_dmtimer_chip.
So we already need:
timer = of_parse_phandle(np, "ti,timers", 0);
and
omap->dm_timer_pdev = of_find_device_by_node(timer);
So why not just do:
struct omap_dm_timer_ops *pdata =
omap_dm_timer_get_ops(omap->dm_timer_pdev);
Regards,
Keerthy

Here we need timer_pdev anyways.

if you dont want to do additional optimizations as part of migration
might be
dev_get_platdata(&omap->dm_timer_pdev->dev);
would be enough.
But, again, PWM driver don't need to know so many details about
DM timer implementation and internal structure as consumer.

That is pretty much what i want to do with the migration series.

Totally understand that. I will follow up with more clean ups once the
code is migrated. Hope that is a reasonable approach.
