| * | include/linux/iopoll.h: include <linux/ktime.h> instead of <linux/hrtimer.h> | Masahiro Yamada | 2017-02-24 | 1 | -1/+1 |
| | | | | | | | | | | | | The timer APIs this header needs are ktime_get(), ktime_add_us(), and ktime_compare(). So, including <linux/ktime.h> seems enough. This commit will cut unnecessary header file parsing.

| * | iopoll: Introduce memory-mapped IO polling macros | Matt Wagantall | 2015-01-19 | 1 | -0/+144 |
| It is sometimes necessary to poll a memory-mapped register until its value satisfies some condition. Introduce a family of convenience macros that do this. Tight-looping, sleeping, and timing out can all be accomplished using these macros.
