Merge branch 'zynq/multiplatform' of git://git.monstr.eu/linux-2.6-microblaze into next/multiplatform
From Michal Simek: This branch depends on arm-soc devel/debug_ll_init branch because we needed Rob's "ARM: implement debug_ll_io_init()" (sha1: afaee03511ba8002b26a9c6b1fe7d6baf33eac86) patch. This branch also depends on zynq/dt branch because of previous major zynq changes. zynq/cleanup branch is subset of zynq/dt. * 'zynq/multiplatform' of git://git.monstr.eu/linux-2.6-microblaze: ARM: zynq: Remove all unused mach headers ARM: zynq: add support for ARCH_MULTIPLATFORM ARM: zynq: make use of debug_ll_io_init() ARM: zynq: remove TTC early mapping ARM: zynq: add clk binding support to the ttc ARM: zynq: use zynq clk bindings clk: Add support for fundamental zynq clks ARM: zynq: dts: split up device tree ARM: zynq: Allow UART1 to be used as DEBUG_LL console. ARM: zynq: dts: add description of the second uart ARM: zynq: move arm-specific sys_timer out of ttc zynq: move static peripheral mappings zynq: remove use of CLKDEV_LOOKUP zynq: use pl310 device tree bindings zynq: use GIC device tree bindings Add/add conflict in arch/arm/Kconfig.debug.
