So, this will result in the warnings on Juno like: sp804: timer clock not found: -517 sp804: arm,sp804 clock not found: -2 sp804: timer clock not found: -517 sp804: arm,sp804 clock not found: -2 This can be ignored as we rely on arch-timers and they are just there in DT for completion. We can disable them in DT if that's fine ?
