clocksource/drivers/timer-sun4i: Add CLOCK_EVT_FEAT_DYNIRQ

2023-02-13T12:10:17+00:00

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.

clocksource/drivers/sun4i: Add definition of clear interrupt

2022-09-20T08:49:39+00:00

To prevent misunderstanding, use TIMER_IRQ_CLEAR instead of TIMER_IRQ_EN in function sun4i_timer_clear_interrupt. Signed-off-by: Victor Hassan Acked-by: Jernej Skrabec Link: https://lore.kernel.org/r/20220906052056.43404-1-victor@allwinnertech.com Signed-off-by: Daniel Lezcano

clocksource/drivers/timer-sun4i: Convert to SPDX identifier

2022-05-18T09:08:59+00:00

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.

clocksource: sun4i: Add missing compatibles

2019-08-26T22:31:39+00:00

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 Acked-by: Daniel Lezcano Signed-off-by: Daniel Lezcano

clocksource/drivers/sun4i: Add a compatible for suniv

2019-05-02T19:55:58+00:00

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. Signed-off-by: Mesih Kilinc Acked-by: Maxime Ripard Acked-by: Daniel Lezcano Signed-off-by: Daniel Lezcano

clocksource/drivers/sun4i: Change name sun4i_timer to timer-sun4i

In order to unify the names in this directory, let's rename the driver to be prefixed with timer-* Signed-off-by: Daniel Lezcano
