rtc: move power of 2 periodic frequency check down into drivers
Move the power of 2 check on frequencies down into individual rtc drivers This is to allow for non power of 2 real time clock periodic interrupts such as those on the pxa27x to be found in the new pxa27x-rtc driver Signed-off-by: Jonathan Cameron <jic23@cam.ac.uk> Signed-off-by: Alessandro Zummo <a.zummo@towertech.it> Cc: David Brownell <david-b@pacbell.net> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
