From ee3e7604095258ec63af3fc837e51065a953a2f7 Mon Sep 17 00:00:00 2001 From: Alexandre Belloni Date: Wed, 8 Jun 2016 01:31:19 +0200 Subject: [PATCH] ARM: dts: at91: ma5d4: properly define crystals frequencies The Denx MA5D4 dts doesn't properly define the slow_xtal and main_xtal frequencies, the PMC then has to fallback to using the RC oscillators whose precision is not really good. As both crystals are populated, define their frequencies, see p17 of http://www.denx-cs.de/sites/all/files/MA5D4.HWM_.002.pdf Also, remove the obsolete main_clock definition.
