From ad9b5f77dffaa38ea830af94cd5de3450318f97c Mon Sep 17 00:00:00 2001 From: Vlad Zakharov Date: Tue, 21 Mar 2017 14:49:47 +0300 Subject: [PATCH 1/3] drivers: timer: Introduce ARC timer driver This commit introduces timer driver for ARC. ARC timers are configured via ARC AUX registers so we use special functions to access timer control registers. This driver allows utilization of either timer0 or timer1 depending on which one is available in real hardware. Essentially only existing timers should be mentioned in board's Device Tree description.

Earlier device tree sources in U-Boot were very simplified and hadn't been updated for quite a long period of time. So this commit is the first step on the road to unified device tree blobs. First of all we re-organize device tree sources for AXS10X boards. As AXS101 and AXS103 boards consist of AXS10X motherboard and AXC001 and AXC003 cpu tiles respectively we add corresponding device tree source files: axs10x_mb.dtsi for motherboard, axc001.dtsi and axc003.dtsi for cpu tiles and axs101.dts and axs103.dts to represent actual boards. Also we delete axs10x.dts as it is no longer used. One more important change - we add timer device to ARC skeleton device tree sources as both ARC700 and ARCHS cores contain such timer. We add core_clk nodes to abilis_tb100, nsim, axc001 and axc003 device tree sources as it is referenced via phandle from timer node in common skeleton.dtsi file.

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.
