e06f1a9ed7 ARM: zynq: dts: split up device tree
The purpose of the created zynq-7000.dtsi file is to describe the
hardware common to all Zynq 7000-based boards.  Also, get rid of the
zynq-ep107 device tree, since it is not hardware anyone can purchase.

Add a zc702 dts file based on the zynq-7000.dtsi.  Add it to the
dts/Makefile so it is built with the 'dtbs' target.

aaf5e0be79 ARM: zynq: Allow UART1 to be used as DEBUG_LL console.
The main UART on the Xilinx ZC702 board is UART1, located at address
e0001000.  Add a Kconfig option to select this device as the low-level
debugging port.  This allows the really early boot printouts to reach
the USB serial adaptor on this board.

For consistency's sake, add a choice entry for UART0 even though it is
the the default if UART1 is not selected.

f58007762f zynq: move static peripheral mappings
Shifting them up into the vmalloc region prevents the following warning,
when booting a zynq qemu target with more than 512mb of RAM:

  BUG: mapping for 0xe0000000 at 0xe0000000 out of vmalloc space

In addition, it allows for reuse of these mappings when the proper
drivers issue requests via ioremap().

There are currently unknown issues with the early uart mapping.  For
now, the uart will be mapped to a known working address.

f7977939e9 zynq: remove use of CLKDEV_LOOKUP
The Zynq support in mainline does not (yet) make use of any of the
generic clk or clk lookup functionality.  Remove what is upstream for
now, until the out-of-tree implementation is in suitable form for
merging.

An important side effect of this patch is that it allows the building of
a Zynq kernel without running into unresolved symbol problems:

   drivers/built-in.o: In function `amba_get_enable_pclk':
   clkdev.c:(.text+0x444): undefined reference to `clk_enable'
   drivers/built-in.o: In function `amba_remove':

   make[2]: *** [vmlinux] Error 1
   make[1]: *** [sub-make] Error 2
   make: *** [all] Error 2

In addition, eliminate Zynq's "use" of the versatile platform, as it is
no longer needed.  As Nick Bowler points out:

   For the record, I think this was introduced by commit 56a34b03ff
   ("ARM: versatile: Make plat-versatile clock optional") which forgot to
   select PLAT_VERSATILE_CLOCK on Zynq.  This is not all that surprising,
   because the fact that Zynq "uses" PLAT_VERSATILE is secretly hidden in
   the Makefile.

   Nevertheless, the only feature from versatile that Zynq needed was the
   clock support, so this patch should *also* delete the secret use of
   plat-versatile by removing this line from arch/arm/Makefile:

      plat-$(CONFIG_ARCH_ZYNQ)      += versatile

2adca5672f A mix of typos and critical fixes.
The most important ones are a duplicated definition of a Kconfig
 variable and the handling of external interrupts for non-DT case.
 The new at91sam9g10 was suffering a recognition issue due to an ID

disregarded.

65bf7ca000 ARM: OMAP3: Beagle: fix OPP customization and initcall ordering
After commit 24d7b40a60 (ARM: OMAP2+:
PM: MPU DVFS: use generic CPU device for MPU-SS), OPPs are registered
using an existing CPU device, not the omap_device for MPU-SS.

First, fix the board file to use get_cpu_device() as required by the
above commit, otherwise custom OPPs will be added to the wrong device.

Second, the board files OPP init is called from the its init_machine
method, and the generic CPU devices are not yet created when
init_machine is run.  Therefore OPP initialization will fail.  To fix,
use a device_initcall() for the board file's OPP customization, and
make the device_initcall board-specific by using a machine_is check.

1d8643dd05 ARM: OMAP3: Fix 3430 legacy mux names for ssi1 signals.
On n900 uart1 pins are not not used for uart, instead they are
used to connect to a cell modem over ssi. Looks like we're
currently missing these signal names for 3430 for some reason,
and only have some of them listed for 3630. Obviously the signals
are there for 3430 if n900 is using them and they are documented
in some TRMs.

Note that these will eventually be replaced by device tree
based pinctrl-single.c driver. But for now these are needed
to verify the SSI pins for devices like Nokia N900.

[    2.324432] omap-mcbsp 49024000.mcbsp: invalid rx DMA channel

Which is because we failed to link the sidetone hwmod for McBSP2/3. The
missing sidetone hwmod link will prevent omap_device_alloc() to append the
DMA resources since we - accidentally - end up having the same number of
resources provided from DT (IO/IRQ) as we have in hwmod for the McBSP ports
without the ST resources.
