This series is a simple improvement for timer-clint and timer-riscv:
Add set_state_shutdown for timer-clint, this hook is used when
switching clockevent from timer-clint to another timer.
Add set_state_oneshot_stopped for both timer-clint and timer-riscv,
this hook is to avoid spurious timer interrupts when KTIME_MAX is
usd. Check commit 8fff52fd5093 ("clockevents: Introduce
CLOCK_EVT_STATE_ONESHOT_STOPPED state") for more information.
Since v1:
- use U64_MAX instead of ULONG_MAX in clint_clock_shutdown, this is
to "produce a 64-bit value on riscv32" as pointed out by Samuel
Jisheng Zhang (3):
clocksource/drivers/timer-riscv: Add set_state_oneshot_stopped
clocksource/drivers/timer-clint: Add set_state_shutdown
clocksource/drivers/timer-clint: Add set_state_oneshot_stopped
