Hi, 

According to "i.MX Linux Reference Manual" , i.MX 8M Mini usages system counter timer (driver/clocksource/timer-imx-sysctr.c ), but I couldn't fine any APIs  which I can integrate in our driver , can you let me know the which system counter timer APIs (pls do share the file path) we can use to enable the timer (one shot and periodic  timer)? please do share the developer document regarding timer, if any.
