* | clock: remove duplicate xdelay declarationsSascha Hauer2015-09-231-2/+1
|/ | | | | | | | ndelay is declared in include/clock.h, udelay in include/common.h and mdelay in include/common.h and include/clock.h. Move them all to include/clock.h and remove duplicates. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* clock: Add a variable with the first timestamp after startupSascha Hauer2014-09-301-0/+2
| | | | | | | For measuring the startup time it's useful to save the first timestamp after the clocksource has been registered. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* clock: introduce non interruptible timeoutJean-Christophe PLAGNIOL-VILLARD2012-10-291-0/+1
| | | | | | | | | | | | | | is_timeout call poller_call if the timeout is >= 100us but on 1-wire bus we need to wait 500us and not more than 930us for the bus reset. So if the poller_call is caller we can not guarantee it. So for this introduce is_non_interruptible_timeout than we only wait. Use it for ndelay too.
