From 7117a44bc0eb5d73dc8aa8df92134f736c2099ac Mon Sep 17 00:00:00 2001 From: Bai Ping Date: Wed, 5 Jun 2019 06:40:52 +0000 Subject: clocksource/drivers/sysctr: Add nxp system counter timer driver support The system counter (sys_ctr) is a programmable system counter which provides a shared time base to the Cortex A15, A7, A53 etc cores. It is intended for use in applications where the counter is always powered on and supports multiple, unrelated clocks. The sys_ctr hardware supports: - 56-bit counter width (roll-over time greater than 40 years) - compare frame(64-bit compare value) contains programmable interrupt generation when compare value <= counter value.
