From 06b4ba529528fbf9c24ce37b7618f4b0264750e2 Mon Sep 17 00:00:00 2001 From: Kevin Hilman Date: Fri, 6 Jul 2012 11:20:28 -0700 Subject: [PATCH] ARM: OMAP2+: omap2plus_defconfig: EHCI driver is not stable, disable it The EHCI driver is not stable enough to be enabled by default. In v3.5, it has at least the following problems: - warning dump during bootup - hang during suspend - prevents CORE powerdomain from entering retention during idle (even when no USB devices connected.) This demonstrates that this driver has not been thoroughly tested and therfore should not be enabled in the default defconfig. In addition, the problems above cause new PM regressions which need be addressed before this driver should be enabled in the default defconfig.
