d01e4afdbb ARM: arm-soc: Cleanups on various subarchitectures
Cleanup patches for various ARM platforms and some of their associated
 drivers. There's also a branch in here that enables Freescale i.MX to be
 part of the multiplatform support -- the first "big" SoC that is moved
 over (more multiplatform work comes in a separate branch later during
 the merge window).

Merge tag 'cleanup' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

Pull ARM SoC cleanups on various subarchitectures from Olof Johansson:
 "Cleanup patches for various ARM platforms and some of their associated
  drivers.  There's also a branch in here that enables Freescale i.MX to
  be part of the multiplatform support -- the first "big" SoC that is
  moved over (more multiplatform work comes in a separate branch later
  during the merge window)."

Conflicts fixed as per Olof, including a silent semantic one in
arch/arm/mach-omap2/board-generic.c (omap_prcm_restart() was renamed to
omap3xxx_restart(), and a new user of the old name was added).

3f54db784a 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.

9a45eb691d ARM: zynq: add support for ARCH_MULTIPLATFORM
The majority of changes are necessary to remove dependencies on header
files within arch/arm/mach-zynq/include/mach:

  uncompress.h
    - Deleted. It is unused for ARCH_MULTIPLATFORM builds.

  uart.h:
    - Move uart definitions out of uart.h into debug/zynq.S, which is
      now the only user

  zynq_soc.h:
    - Move SCU address definitions into common.c.
    - Other #defines, such as PERIPHERAL_CLOCK_RATE, TTC0_BASE, etc, are
      unused and can be dropped

49c9e60eaa ARM: imx6q: let users input debug uart port number
imx6q gets 5 uart ports in total.  Different board design may choose
different port as debug uart.  For example, imx6q-sabresd uses UART1,
imx6q-sabrelite uses UART2 and imx6q-arm2 uses UART4.  Rather than
bloating DEBUG_LL choice list with all these uart ports, the patch
introduces DEBUG_IMX6Q_UART_PORT for users to input uart port number
when DEBUG_IMX6Q_UART is selected inside DEBUG_LL choice.

Since the code can never get executed on ARMv6 but might
be built in a configuration that has ARMv6 enabled, it's
safe to just mark it in the assembly source for being

Move imx debug-macro.S over to common debug macro directory.  It
removes the inclusion to hardware.h by hard-coding the physical
address of uart port and copying IMX_IO_P2V from hardware.h.

Since we will need a common solution, which might use a fixed virtual
address for uart port across platforms, we make a copy of IMX_IO_P2V
here as a temporary solution to enable low-level debug for imx
multi-platform build.
