From e6639117d624d5c8f531d22456a69e38dc23c501 Mon Sep 17 00:00:00 2001 From: Peter De Schrijver Date: Thu, 12 Jun 2014 18:58:27 +0300 Subject: kernel: add calibration_delay_done() Add calibration_delay_done() call and dummy implementation. This allows architectures to stop accepting registrations for new timer based delay functions.
