clocksource/drivers/sprd: Enable register for timer counter from 32 bit to 64 bit

2025-11-26T10:24:26+00:00

Using 32 bit for suspend compensation, the max compensation time is 36 hours(working clock is 32k).In some IOT devices, the suspend time may be long, even exceeding 36 hours. Therefore, a 64 bit timer counter is needed for counting.

clocksource/drivers/sprd: Register one always-on timer to compensate suspend time

2018-07-26T09:26:34+00:00

Since the clocksource framework has introduced one suspend clocksource to compensate the suspend time, this patch registers one always-on timer as the suspend clocksource. Signed-off-by: Baolin Wang Signed-off-by: Daniel Lezcano

clocksource/drivers/spreadtrum: Add timer driver for the Spreadtrum SC9860 platform

2018-01-08T16:57:24+00:00

The Spreadtrum SC9860 platform will use the architected timers as local clock events, but we also need a broadcast timer device to wake up the CPUs when the CPUs are in sleep mode. The Spreadtrum timer can support 32-bit or 64-bit counters, as well as supporting period mode or one-shot mode.
