arm: orion5x: basic Device Tree support This commit adds basic DT support for the Orion5x SoC family. It adds an orion5x.dtsi description of the Orion5x SoC as well as the needed DT_MACHINE structure to support boards converted to DT in the future. So far, the Device Tree contains the interrupt controller, the GPIO bank, the UART controllers, the SPI controller, the watchdog, the SATA controller, the I2C controller and the cryptographic engine.

arm: orion5x: convert 'LaCie Ethernet Disk mini v2' to Device Tree This commit converts the 'LaCie Ethernet Disk mini v2' board to the Device Tree. All devices that have existing Device Tree bindings are converted over to the Device Tree, the other devices remain instantiated in the old way, until the respective drivers get the needed Device Tree bindings.

ARM: delete struct sys_timer Now that the only field in struct sys_timer is .init, delete the struct, and replace the machine descriptor .timer field with the initialization function itself. This will enable moving timer drivers into drivers/clocksource without having to place a public prototype of each struct sys_timer object into include/linux; the intent is to create a single of_clocksource_init() function that determines which timer driver to initialize by scanning the device dtree, much like the proposed irqchip_init() at: http://www.spinics.net/lists/arm-kernel/msg203686.html Includes mach-omap2 fixes from Igor Grinberg.
