Merge branch 'devicetree/next' of git://git.secretlab.ca/git/linux-2.6
* 'devicetree/next' of git://git.secretlab.ca/git/linux-2.6: of_mdio: Don't phy_scan_fixups() twice Devicetree: Expand on ARM Primecell binding documentation dt: Add empty of_match_node() macro dt: add empty dt helpers for non-dt build devicetree: fix build error on drivers/tty/serial/altera_jtaguart.c devicetree: Add ARM pl022 spi controller binding doc devicetree: Add ARM pl061 gpio controller binding doc of/irq: of_irq_find_parent: check for parent equal to child MAINTAINERS: update devicetree maintainers dt: add helper to read 64-bit integers tty: use of_match_ptr() for of_match_table entry OF: Add of_match_ptr() macro dt: add empty for_each_child_of_node, of_find_property devicetree: Document Qualcomm and Atmel prefixes serial/imx: add of_alias_get_id() reference back dt: add of_alias_scan and of_alias_get_id devicetree: Add a registry of vendor prefixes
