Signed-off-by: Biju Das Reviewed-by: Fabrizio Castro --- This patch is tested against renesas-dev I have executed on inconsistency-check, nanosleep and clocksource_switch selftests on this arm64 SoC. The inconsistency-check and nanosleep tests are working fine.The clocksource_switch asynchronous test is failing due to inconsistency-check failure on "arch_sys_counter". But if i skip the clocksource_switching of "arch_sys_counter", the asynchronous test is passing for CMT0/1/2/3 timer.
