- remove improper error message on kirkwood
- a couple a clean-up patch generated from automatic tools
- clean-up in assembly code allowing using LLVM
* tag 'mvebu-arm-5.2-1' of git://git.infradead.org/linux-mvebu:
ARM: mvebu: drop return from void function
ARM: mvebu: prefix coprocessor operand with p
ARM: mvebu: drop unnecessary label
ARM: mvebu: fix a leaked reference by adding missing of_node_put
ARM: mvebu: kirkwood: remove error message when retrieving mac address

There was NVMEM support added to of_get_mac_address, so it could now return
ERR_PTR encoded error values, so we need to adjust all current users of
of_get_mac_address to this new fact.

Kirkwood has always had the ability to retrieve the local-mac-address
from the hardware (usually this was configured by the bootloader). This
is particularly useful when dealing with a legacy non-DT aware
bootloader.
The "error" message just indicated that the board used an old bootloader
and in many cases users can't do anything about this. The message
probably should have been pr_info() to inform the user that the kernel
has been helpful but rather than than let's remove it entirely to make
the kernel less noisy.

Now that we have a custom printf format specifier, convert users of
full_name to use %pOF instead. This is preparation to remove storing
of the full path string for each node.

Pull ARM SoC cleanups from Olof Johansson:
"The cleanup branch keeps going down in size as we've completed a lot
of the major legacy platform removals and conversions.
A handful of changes this time around, some of the themes or larger
sets are:
- A bunch of i.MX cleanups around platform detection, init call cleanups
- Misc fixes of missing/implicit includes
- Removal of ARCH_[WANT_OPTIONAL|REQUIRE]_GPIOLIB"

Use helper of_platform_default_populate() in linux/of_platform
when possible, instead of calling of_platform_populate() with
the default match table.

The kirkwood_disable_mbus_error_propagation is not exported or declared
elsewhere, so make it static to avoid the following warning:
arch/arm/mach-mvebu/kirkwood.c:153:6: warning: symbol 'kirkwood_disable_mbus_error_propagation' was not declared. Should it be static?

Since DT support is now available for the LEDs found on the LaCie
netxbig boards (Kirkwood-based), then the old-fashion netxbig board
setup file is no longer needed. This patch removes this file.

There is currently no DT binding for the CPLD which controls the LEDs
on the Net 2Big and Net 5Big. So use a platform device.

place.

Until now, the mvebu-mbus was guessing by itself whether hardware I/O
coherency was available or not by poking into the Device Tree to see
if the coherency fabric Device Tree node was present or not.
However, on some upcoming SoCs, the presence or absence of the
coherency fabric DT node isn't sufficient: in CONFIG_SMP, the
coherency can be enabled, but not in !CONFIG_SMP.
In order to clean this up, the mvebu_mbus_dt_init() function is
extended to get a boolean argument telling whether coherency is
enabled or not. Therefore, the logic to decide whether coherency is
available or not now belongs to the core SoC code instead of the
mvebu-mbus driver itself, which is much better.

Convert the kirkwood t5325-setup.c to mostly device tree for
mach-mvebu. Part of the audio setup needs to remain in C for the
moment until suitable bindings are designed and implemented. So add
board code, triggered by the compatibility string.

Move the kirkwood DT support into mach-mvebu, and make them part of
ARCH_MULTI_V5. Minimal changes have been made in order to make it
boot. Cleanup of the header files and integration with mvebu will
take place in following patches.
In order to help Debian transition between mach-kirkwood and
mach-mvebu, the DTS files are compiled for both, allowing Debian to
continue using mach-kirkwood until all remaining boards are supported
by mach-mvebu. Debian is then expected to simply swap from
mach-kirkwood to mach-mvebu and mach-kirkwood will be removed.
