From c026c98739c7e435440e76cbcd96e0f8ebeeada0 Mon Sep 17 00:00:00 2001 From: Anton Vorontsov Date: Thu, 19 Feb 2009 19:02:23 +0300 Subject: powerpc/83xx: Do not configure or probe disabled FSL DR USB controllers On MPC837X CPUs Dual-Role USB isn't always available (for example DR USB pins can be muxed away to eSDHC). U-Boot adds status = "disabled" property into the DR USB nodes to indicate that we must not try to configure or probe Dual-Role USB, otherwise we'll break eSDHC support on targets with MPC837X CPUs.
