linux-toradex.git/drivers/clocksource/Makefile, branch v5.17-rc5 Linux kernel for Apalis and Colibri modules clocksource/drivers: Add MStar MSC313e timer support 2021-12-20T12:28:28+00:00 Romain Perier romain.perier@gmail.com 2021-12-17T19:57:22+00:00 5fc1f93f69989e72be7a84ded6ee867d6415f690 The MSC313e-compatible SoCs have 3 timer hardware blocks. All of these are free running 32-bit increasing counters and can generate interrupts. Based onto a maximum value register, each timer can either count from 0 to max, one time then stop (which generates interrupts) or can count from 0 to max and then roll. This commit adds basic support for these timers, the first timer block being used as clocksource/sched_clock and delay, while the others will be used as clockevents.
