ethernet: ti: am65-cpts: add routines to support taprio offload

Browse source

TAPRIO/EST offload support in CPSW2G requires EST scheduler
function enabled in CPTS. So this patch add a function to
set cycle time for EST scheduler.  It also add a function for
getting time in ns of PHC clock for taprio qdisc configuration.
Mostly to verify if timer update is needed or to get actual
state of oper/admin schedule.
