From 3a61a5dae49bf3d1afb7f75c8acb3607f26565af Mon Sep 17 00:00:00 2001 From: Nicolas Ferre Date: Thu, 19 Jan 2012 10:13:40 +0100 Subject: ARM: at91/tc: add device tree support to atmel_tclib Device tree support added to atmel_tclib: the generic Timer Counter library. This is used by the clocksource/clockevent driver tcb_clksrc. The current DT enabled platforms are also modified to use it: - .dtsi files are modified to add Timer Counter Block entries - alias are created to allow identification of each block - clkdev lookup tables are added for clocks identification.
