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.

I have one, but I'm not using it because of it's large size, and I doubt anybody else is using it either. We do have minimal omap2420-h4.dts in place, so if anybody wants more support on H4, patches are welcome. So let's just remove it as that helps us making mach-omap2 to be device tree only.
