[PATCH V2 0/2] clockevents: Add helpers to verify state of a clockevent device
From: Viresh Kumar
Date: Thu May 21 2015 - 04:07:04 EST
Hi Thomas,
Some clockevent drivers, once migrated to use per-state callbacks, would
need to verify 'state' of the clockevent device in their callbacks or
interrupt handler.
(Details of these drivers are posted by Thomas earlier:
https://lkml.org/lkml/2015/5/20/454)
In order to discourage drivers from using CLK_EVT_STATE_* symbols
directly and to make it easy grep for abusers of these symbols, this
series introduces few accessor functions. The second patch updates core
code to use these functions.
V1->V2:
- Don't move 'enum clock_event_state' to core's internal file.
- Move accessor functions to clockchips.h and mark them inline.
- New patch, 2/2.
- s/\<evt\>/dev in accessor functions
Rebased-over: tip/timers/core (dependency on 8fff52fd5093 ("clockevents:
Introduce CLOCK_EVT_STATE_ONESHOT_STOPPED state"))
