[PATCH 01/17] ARM: dts: lpc18xx: add cgu and ccu clock-controller nodes

Tue Jul 14 06:39:36 PDT 2015
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.
