Merge tag 'omap-devel-d-for-3.6' of git://git.kernel.org/pub/scm/linux/kernel/git/pjw/omap-pending into fixes-non-critical
Some OMAP AM35xx fixes. The powerdomain and clockdomain data for the AM35xx are finally fixed. The AM35xx EMAC/MDIO Ethernet controller integration code has been converted to use the OMAP device and hwmod framework. Also the UART4 and HSOTGUSB warnings have been fixed.
