From 1c694102a56895b7aea636f026955cc5d7ee340d Mon Sep 17 00:00:00 2001 From: Vlad Zakharov Date: Tue, 21 Mar 2017 14:49:49 +0300 Subject: arc: use timer driver for ARC boards This commit replaces legacy timer code with usage of arc timer driver. It removes arch/arc/lib/time.c file and selects CONFIG_CLK, CONFIG_TIMER and CONFIG_ARC_TIMER options for all ARC boards by default. Therefore we remove CONFIG_CLK option from less common axs101 and axs103 defconfigs. Also it removes legacy CONFIG_SYS_TIMER_RATE config symbol from axs10x.h, tb100.h and nsim.h configs files as it is no longer required.
