This suggests that it might not be such a good idea to call
arch_timer_get_rate() and arch_timer_read_counter() in the first place.
I don't know of any other way to convert seconds into watchdog ticks.
[ On a side note, arch_timer_get_rate() can return 0 if ARM_ARCH_TIMER
is not configured. You'll need to check for that. ]
Check the Kconfig for this driver. It requires ARM_ARCH_TIMER.
It is hard to imagine that the watchdog would be the only driver which
needs this clock. Isn't there some clock API call that can be used
instead ?
If there is, I'd love to know it. There's no 'device' for this driver, so I don't think the clk API will work.
Maybe ask on the arm mailing list ?

As for acpi_parse_entries, we will need some feedback from the acpi
maintainers. If the intent is that this function can be called from
drivers, it should be exported.
Agreed.
