From 036582f76ad900e4c1b9ec290ce66c6f698bd00d Mon Sep 17 00:00:00 2001 From: Tony Lindgren Date: Mon, 25 Nov 2013 15:17:09 -0800 Subject: ARM: OMAP2+: Add support for board specific auxdata quirks Looks like some boards need to fill in the auxdata before we call of_platform_populate(). Let's add support for auxdata quirks like we already have for pdata quirks for legacy drivers.

Note that we still need to initialize most things with platform data as the drivers are lacking support for device tree.
