[PATCH v2 09/10] ARM: berlin: rework chip and system controller nodes for BG2CD

Antoine Tenart
2015-03-06T15:06:46Z

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.
