[PATCH 10/11] ARM: berlin: rework chip and system controller nodes for BG2CD

Antoine Tenart antoine.tenart at free-electrons.com
Wed Feb 11 08:15:31 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.
