2020-08-24clocksource/drivers/timer-gx6605s: Fixup counter reloadGuo Ren1-0/+1
When the timer counts to the upper limit, an overflow interrupt is generated, and the count is reset with the value in the TIME_INI register. But the software expects to start counting from 0 when the count overflows, so it forces TIME_INI to 0 to solve the potential interrupt storm problem.

2018-11-02clocksource/drivers/c-sky: Add gx6605s SOC system timerGuo Ren1-0/+154
The driver is for gx6605s SOC system timer and there are two same timers in gx6605s. We use one for clkevt and another one for clksrc. The timer is mmio map to access, so we need give mmio address in dts. The counter at 0x0 offset is clock event. The counter at 0x40 offset is clock source.
