2023-02-13clocksource/drivers/timer-sun4i: Add CLOCK_EVT_FEAT_DYNIRQYangtao Li1-1/+2
Add CLOCK_EVT_FEAT_DYNIRQ to allow the IRQ could be runtime set affinity to the cores that needs wake up, otherwise saying core0 has to send IPI to wakeup core1. With CLOCK_EVT_FEAT_DYNIRQ set, when broadcast timer could wake up the cores, IPI is not needed. After enabling this feature, especially the scene where cpuidle is enabled can benefit.

2022-05-18clocksource/drivers/timer-sun4i: Convert to SPDX identifierThomas Gleixner1-4/+1
The license information clearly states GPL version 2 only. The extra text which excludes warranties is an excerpt of the corresponding GPLv2 clause 11. So the SPDX identifier covers it completely.

2019-08-27clocksource: sun4i: Add missing compatiblesMaxime Ripard1-0/+4
Newer Allwinner SoCs have different number of interrupts, let's add different compatibles for all of them to deal with this properly. Signed-off-by: Maxime Ripard <[email protected]> Acked-by: Daniel Lezcano <[email protected]> Signed-off-by: Daniel Lezcano <[email protected]>
2019-05-02clocksource/drivers/sun4i: Add a compatible for sunivMesih Kilinc1-1/+4
The suniv (new F-series) chip has a timer with less functionality than the A10 timer, e.g. it has only 3 channels. Add a new compatible for it. As we didn't use the extra channels on A10 either now, the code needn't to be changed. The suniv chip is based on ARM926EJ-S CPU, thus it has no architecture timer. Register sun4i_timer as sched_clock on it.
