2016-12-25	clocksource: Use a plain u64 instead of cycle_t	Thomas Gleixner	1	-6/+6
	There is no point in having an extra type for extra confusion. u64 is unambiguous. Conversion was done with the following coccinelle script: @rem@ @@ -typedef u64 cycle_t; @fix@ typedef cycle_t; @@ -cycle_t +u64 Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Cc: Peter Zijlstra <peterz@infradead.org> Cc: John Stultz <john.stultz@linaro.org>
2015-01-02	timecounter: provide a macro to initialize the cyclecounter mask field.	Richard Cochran	1	-1/+4
	There is no need for users of the timecounter/cyclecounter code to include clocksource.h just for a single macro. Signed-off-by: Richard Cochran <richardcochran@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2014-12-30	timecounter: keep track of accumulated fractional nanoseconds	Richard Cochran	1	-7/+12
	The current timecounter implementation will drop a variable amount of resolution, depending on the magnitude of the time delta. In other words, reading the clock too often or too close to a time stamp conversion will introduce errors into the time values. This patch fixes the issue by introducing a fractional nanosecond field that accumulates the low order bits.

2014-12-30	timecounter: provide a helper function to shift the time.	Richard Cochran	1	-0/+9
	Some PTP Hardware Clock drivers use a struct timecounter to represent their clock. To adjust the time by a given offset, these drivers all perform a two step read/write of their timecounter. However, it is better and simpler just to adjust the offset in one step. This patch introduces a little routine to help drivers implement the adjtime method.

2014-12-30	time: move the timecounter/cyclecounter code into its own file.	Richard Cochran	1	-0/+122
	The timecounter code has almost nothing to do with the clocksource code. Let it live in its own file. This will help isolate the timecounter users from the clocksource users in the source tree.
