The Meson Timer IP block has two clock inputs: - clk81 for using the system clock as timebase - xtal for a timebase with 1us, 10us, 100us and 1ms resolution The clocksource driver does not use these yet, but it's still a good idea to add them as this describes how the hardware actually works internally.
