Pull Devicetree updates from Rob Herring:
 "A bit bigger than normal as I've been busy this cycle.

  There's a few things with dependencies and a few things subsystem
  maintainers didn't pick up, so I'm taking them thru my tree.

  The fixes from Johan didn't get into linux-next, but they've been
  waiting for some time now and they are what's left of what subsystem
  maintainers didn't pick up.

  Summary:

   - Sync dtc with upstream version v1.4.7-14-gc86da84d30e4

   - Work to get rid of direct accesses to struct device_node name and
     type pointers in preparation for removing them. New helpers for
     parsing DT cpu nodes and conversions to use the helpers. printk
     conversions to %pOFn for printing DT node names. Most went thru
     subystem trees, so this is the remainder.

   - Fixes to DT child node lookups to actually be restricted to child
     nodes instead of treewide.

   - Refactoring of dtb targets out of arch code. This makes the support
     more uniform and enables building all dtbs on c6x, microblaze, and
     powerpc.

   - Various DT binding updates for Renesas r8a7744 SoC

   - Vendor prefixes for Facebook, OLPC

   - Restructuring of some ARM binding docs moving some peripheral
     bindings out of board/SoC binding files

   - New "secure-chosen" binding for secure world settings on ARM

   - Dual licensing of 2 DT IRQ binding headers"

libfdt: Ensure INT_MAX is defined in libfdt_env.h

2018-09-19T22:10:06+00:00

The next update of libfdt has a new dependency on INT_MAX. Update the
instances of libfdt_env.h in the kernel to either include the necessary
header with the definition or define it locally.

ARM: 8786/1: Debug kernel copy by printing

2018-09-19T09:44:50+00:00

It may happen that when we relocate the kernel we corrupt other
sensible memory (e.g. the memory needed by U-Boot for dealing
with bootm command) while copying the kernel. If we overwrite
the content of the memory area used by U-Boot's command bootm
(described by U-Boot's parameters bootm_low and bootm_size),
the kernel won't be able to boot. Troubleshooting the problem
then is not straightforward.

This commit allows the user to easily print information on
where the kernel gets copied from/to in order to help with the
design of the system memory map (e.g. bootm_low and bootm_size)
at boot up.

arm: port KCOV to arm

2018-06-14T22:55:24+00:00

KCOV is code coverage collection facility used, in particular, by
syzkaller system call fuzzer.  There is some interest in using syzkaller
on arm devices.  So port KCOV to arm.

On implementation level this merely declares that KCOV is supported and
disables instrumentation of 3 special cases.  Reasons for disabling are
commented in code.

Tested with qemu-system-arm/vexpress-a15.

ARM: 8767/1: add support for building ARM kernel with clang

2018-05-19T10:53:46+00:00

Use cc-options call for compiler options which are not available
in clang. With this patch an ARMv7 multi platform kernel can be
successfully build using clang (tested with version 5.0.1).

ARM: replace unnecessary perl with sed and the shell $(( )) operator

2018-05-19T10:35:56+00:00

You can build a kernel in a cross compiling environment that doesn't
have perl in the $PATH. Commit 429f7a062e3b broke that for 32 bit
ARM. Fix it.

As reported by Stephen Rothwell, it appears that the symbols can be
either part of the BSS section or absolute symbols depending on the
binutils version.  When they're an absolute symbol, the $(( ))
operator errors out and the build fails.  Fix this as well.

2018-05-19T10:35:56+00:00

The hypervisor setup before __enter_kernel destroys the value
sotred in r1. The value needs to be restored just before the jump.
