[PATCH 2/2] ARM: dts: AM33XX: don't redefine OCP bus and device nodes
Javier Martinez Canillas
javier.martinez at collabora.co.uk
Sat Aug 10 13:05:11 EDT 2013
The On Chip Peripherals (OCP) device node is a simplified
representation of the AM33XX SoC interconnect. An OCP dev
node is already defined in the am33xx.dtsi Device Tree
source file included by am33xx based boards so there is
no need to redefe this on each board DT file.
Also, the OCP and IP modules directly connected to it are SoC
internal details that is better to keep outside of board files.
