Pull DeviceTree updates from Rob Herring:
 "A bigger diffstat than usual with the kbuild changes and a tree wide
  fix in the binding documentation.

  Summary:

   - kbuild cleanups and improvements for dtbs

   - Code clean-up of overlay code and fixing for some long standing
     memory leak and race condition in applying overlays

   - Improvements to DT memory usage making sysfs/kobjects optional and
     skipping unflattening of disabled nodes. This is part of kernel
     tinification efforts.

   - Final piece of removing storing the full path for every DT node.
     The prerequisite conversion of printk's to use device_node format
     specifier happened in 4.14.

   - Sync with current upstream dtc. This brings additional checks to
     dtb compiling.

   - Binding doc tree wide removal of leading 0s from examples

   - RTC binding documentation adding missing devices and some
     consolidation of duplicated bindings

   - Vendor prefix documentation for nutsboard, Silicon Storage
     Technology, shimafuji, Tecon Microprocessor Technologies, DH
     electronics GmbH, Opal Kelly, and Next Thing"

dt-bindings: Remove leading zeros from bindings notation

2017-11-09T23:05:05+00:00

Improve the binding example by removing all the leading zeros to fix the
following dtc warnings:

Warning (unit_address_format): Node /XXX unit name should not have leading 0s

Converted using the following command:

perl -p -i -e 's/\@0+([0-9a-f])/\@$1/g' `find ./Documentation/devicetree/bindings "*.txt"`

Some unnecessary changes were manually fixed.

dt-bindings: timer: renesas, cmt: Fix SoC-specific compatible values

2017-10-19T21:48:53+00:00

While the new family-specific compatible values introduced by commit
6f54cc1adcc8957f ("devicetree: bindings: R-Car Gen2 CMT0 and CMT1
bindings") use the recommended order ",-", the
new SoC-specific compatible values still use the old and deprecated
order ",-".

Switch the SoC-specific compatible values to the recommended order while
there are no upstream users of these compatible values yet.

Fixes: 7f03a0ecfdc786c1 ("devicetree: bindings: r8a73a4 and R-Car Gen2 CMT bindings")
Fixes: 63d9e8ca0dd4bfa4 ("devicetree: bindings: Deprecate property, update example")

devicetree: bindings: Remove deprecated properties

The deprecated DT properties are part of the GIT history,
no need to keep them around any longer.

devicetree: bindings: Remove unused 32-bit CMT bindings

2017-08-29T09:08:03+00:00

Remove the 32-bit CMT compat strings to reduce maintenance burden.

It should be fine to break DT compatibility because the 32-bit
CMT DT binding was never part of any upstream DTS file.

devicetree: bindings: R-Car Gen2 CMT0 and CMT1 bindings

2017-08-29T09:07:59+00:00

Add documentation for new separate CMT0 and CMT1 DT compatible strings
for R-Car Gen2. These compat strings allow us to enable CMT1-specific
features in the driver. The old compat strings will be deprecated in
the not so distant future.

devicetree: bindings: Remove sh7372 CMT binding

2017-08-29T09:07:58+00:00

Remove the sh7372 CMT compat string to reduce maintenance burden.

It should be fine to break DT compatibility because:
1) The sh7372 SoC support has been removed from upstream
2) The sh7372 CMT DT binding was never part of upstream DTS
3) The CMT driver never matches on the sh7372 binding
