[PATCH 09/11] ARM: berlin: rework chip and system controller nodes for BG2

Wed Feb 11 08:15:30 PST 2015


The chip and system controller nodes are now handled by the Berlin
controller mfd driver. Its sub-devices are then registered by the mfd
driver and let the drivers be probed properly, using their own
sub-nodes.

Rework the device tree to take this changes into account.
