From 5c697664858945b7a67e74e9c196a8f705c9e88f Mon Sep 17 00:00:00 2001 From: Thomas Petazzoni Date: Tue, 22 Apr 2014 23:26:17 +0200 Subject: ARM: orion5x: convert DT to use the mvebu-mbus driver This commit switches the Orion5x Device Tree files to use the DT representation and probing for the mvebu-mbus driver. The changes are mainly: * Re-organize the DT to follow the same organization as the one used on Armada 370/XP, which is needed for mvebu-mbus to work: a top-level soc { ... } node, which corresponds to the MBus bus, and a sub-node internal-regs { ... } for all peripherals whose register sit only in the "Internal Register Window". This change re-indents by one level the definition of all nodes in the Device Tree, which explains the large change. * Use custom functions orion5x_dt_init_early() and orion5x_dt_init_time() instead of orion5x_init_early() and orion5x_timer_init() as we now want the MBus driver to be probed from the Device Tree. We still use the old-style timer initialization, but that will be changed in a followup commit.
