From 25515b630c3c49945953cc048d6051441ac220d2 Mon Sep 17 00:00:00 2001 From: Tony Lindgren Date: Thu, 23 Jul 2015 22:33:18 -0700 Subject: [PATCH] ARM: dts: Add minimal clocks for dm814x Use fixed clocks until we have a clock driver for the PLL. The mux and divider composite clocks work the same way as on dm816x and am335x.
