#1227679 — [PATCH v1 0/3] Support the timer on RK3368 SoC

Message-ID<q9ZGr-67w-35@gated-at.bofh.it>
Timer0~11 count up from zero to a programmed value and
generate an interrupt when the count reaches the programmed value.

TIMER0, TIMER1, TIMER2, Timer3, TIMER4 and TIMER5 are in the CPU
subsystem, using timer ch0 ~ ch5 respectively. The timer clock is 24MHz
OSC.

This series are found on RK3368 SoC, verified on rk3368 evb board.


Changes in v1:
- As Russell, Thomas, Daniel comments, let's replace NO_IRQ by '!irq'.
- As the Heiko comments, add the "rockchip,rk3368-timer" for timer.
  Although the 'rockchip,rk3288-timer' is working for RK3368, need to add the
  'rockchip,rk3368-timer' for the rk3368-spec timer in the future.

Caesar Wang (3):
  clocksource: rockchip: Make the driver more readability and compatible
  arm64: Enable the timer on Rockchip architecture
  arm64: dts: rockchip: Add the needed timer for RK3368 SoC

In reply to#1227679
There is a need of a broadcast timer in this case to ensure proper
wakeup when the cpus are in sleep mode and a timer expires.
