I don't have access to omap36xx hardware myself, but give a try for the following patch: From: Tero Kristo Date: Wed, 29 Jan 2014 11:03:46 +0200 Subject: [PATCH] ARM: dts: omap36xx: fix omap96m_alwon_fck OMAP36xx has different hardware implementation for the omap96m_alwon_fck compared to other OMAP3 variants. Reflect this properly in the dts file.
