[PATCH 6/6 v2] ARM: integrator: convert platform devices to Device Tree

From: Linus Walleij <hidden>
Date: 2012-09-01 03:55:58
Also in: linux-arm-kernel
Subsystem: arm port, the rest · Maintainers: Russell King, Linus Torvalds

Possibly related (same subject, not in this thread)

This moves the physmap flash and SMSC91x ethernet devices
over to the device tree, moving the static board code down
into the #ifndef CONFIG_OF section.

Signed-off-by: Linus Walleij <redacted>
