From ba2db535a99dc004ab6b7952625029ec196514b9 Mon Sep 17 00:00:00 2001 From: Joachim Eastwood Date: Wed, 1 Apr 2015 14:42:00 +0200 Subject: [PATCH] ARM: dts: lpc18xx: add cgu and ccu clock-controller nodes Add CGU and CCU clock-controller nodes for lpc18xx together with the fixed input clocks. Also remove the temporary fixed-factor pll1 clock from both lpc18xx and lpc4350-hitex-eval DTS now that proper clock drivers are inplace.
