From: Afzal Mohammed Date: Mon, 27 May 2013 14:36:53 +0000 (+0530) Subject: ARM: OMAP2+: AM43x: basic dt support X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=bb256f803c9f620eb5a7d1c02e53360392cffbdd;p=linux-beck.git ARM: OMAP2+: AM43x: basic dt support Describe minimal DT boot machine details for AM43x based SoC's. AM43x SoC's are ARM Cortex-A9 based with one core. AM43x is similar to AM335x w.r.t L4 PER/WKUP memory map. AM43x has a sync timer, here that is being used as clocksource, while 1ms dmtimer as clockevent.
