From def0641e2f61a545a852887e15a19231c4c863c4 Mon Sep 17 00:00:00 2001 From: Stefan Agner Date: Wed, 27 May 2015 14:47:52 +0200 Subject: [PATCH] ARM: dts: add property for maximum ADC clock frequencies The ADC clock frequency is limited depending on modes used. Add device tree property which allow to set the mode used and the maximum frequency ratings for the instance. These allows to set the ADC clock to a frequency which is within specification according to the actual mode used.
