Understanding of S3C6410 timer related codes in Linux kernel

This article describes the relevant codes in time.c based on the mini6410 platform, mainly describing the understanding of some codes. Paste the code first: 1 /* we use the shifted arithmetic to work out the ratio of timer ticks 2 * to use cs, as often the peripheral clock is not a nice ev
