Ivan Grokhotkov	1af6384349	esp_timer: lock-free implementation of esp_timer_get_time ... The implementation of esp_timer_get_time used a critical section, which resulted in a call time of ~1.8us. To make esp_timer_get_time more useable as a high-resolution time source, this change replaces the lock with polling. Call time is reduced to ~0.7us.	2017-09-01 10:34:36 +08:00
