Thanks! Even the PIT block on other Vybrid SoCs have differences from the one integrated on mvf600, we can handle them using device tree compatible string. And that's why we need to encode SoC name in compatible. > [Lu Jingchang-B35083] > PIT0 and PIT1 can be chained to build a 64-bit timer, so PIT2 and PIT3 are selected as the clocksource and clockevent device, and leave PIT0 and PIT1 unused for anyone else who needs them. Thanks! This could be an useful info to be in the comment.
