Subject: [PATCH 0/3] clocksouce/timer-clint|riscv: some improvements

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.

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
