Pull devicetree updates from Rob Herring:

 - Convert various DT (non-binding) doc files to ReST

 - Various improvements to device link code

 - Fix __of_attach_node_sysfs refcounting bug

 - Add support for 'memory-region-names' with reserved-memory binding

dt-bindings: timer: Move snps,dw-apb-timer DT schema from rtc

2020-05-22T22:02:33+00:00

This binding file doesn't belong to the rtc seeing it's a pure timer
with no rtc facilities like days/months/years counting and alarms.
So move the YAML-file to the Documentation/devicetree/bindings/timer/
directory.

dt-bindings: rtc: Convert snps,dw-apb-timer to DT schema

2020-05-22T22:02:26+00:00

Modern device tree bindings are supposed to be created as YAML-files
in accordance with DT schema. This commit replaces Synopsys DW Timer
legacy bare text binding with YAML file. As before the binding file
states that the corresponding dts node is supposed to be compatible
with generic DW APB Timer indicated by the "snps,dw-apb-timer"
compatible string and to provide a mandatory registers memory range,
one timer interrupt, either reference clock source or a fixed clock
rate value. It may also have an optional APB bus reference clock
phandle specified.

dt-bindings: Remove cases of 'allOf' containing a '$ref'

2020-05-03T16:10:41+00:00

json-schema versions draft7 and earlier have a weird behavior in that
any keywords combined with a '$ref' are ignored (silently). The correct
form was to put a '$ref' under an 'allOf'. This behavior is now changed
in the 2019-09 json-schema spec and '$ref' can be mixed with other
keywords. The json-schema library doesn't yet support this, but the
tooling now does a fixup for this and either way works.

This has been a constant source of review comments, so let's change this
treewide so everyone copies the simpler syntax.

Scripted with ruamel.yaml with some manual fixups. Some minor whitespace
changes from the script.

dt-bindings: Clean-up schema indentation formatting

2020-04-16T21:59:22+00:00

Fix various inconsistencies in schema indentation. Most of these are
list indentation which should be 2 spaces more than the start of the
enclosing keyword. This doesn't matter functionally, but affects running
scripts which do transforms on the schema files.

Merge tag 'rtc-5.7' of git://git.kernel.org/pub/scm/linux/kernel/git/abelloni/linux

2020-04-04T17:38:01+00:00

Pull RTC updates from Alexandre Belloni:
 "More cleanup this cycle, with the final goal of removing the
  rtc_time_to_tm and rtc_tm_to_time wrappers. All the drivers that have
  been modified for this now are ready for the end of times (whether it
  happens in 2033, 2038, 2106, 2127 or even 4052). There is also a
  single new driver and the usual fixes and features.

  Summary:

  Subsystem:

   - The rtc_time_to_tm and rtc_tm_to_time wrappers have finally been
     removed and only the 64bit version remain.

   - hctosys now works with drivers compiled as modules

  New driver:

   - MediaTek MT2712 SoC based RTC

  Drivers:

   - set range for 88pm860x, au1xxx, cpcap, da9052, davinci, ds1305,
     ds1374, mcp5121, pl030, pl031, pm8xxx, puv3, sa1100, sirfsoc,
     starfire, sun6i

   - ds1307: DS1388 oscillator failure detection and watchdog support

   - jz4740: JZ4760 support

   - pcf85063: clock out pin support

   - sun6i: external 32k oscillator is now optional, the range is now
     handled by the core, providing a solution for 2034"

dt-bindings: Add missing 'additionalProperties: false'

2020-03-31T15:03:17+00:00

Setting 'additionalProperties: false' is frequently omitted, but is
important in order to check that there aren't extra undocumented
properties in a binding.

Ideally, we'd just add this automatically and make this the default, but
there's some cases where it doesn't work. For example, if a common
schema is referenced, then properties in the common schema aren't part
of what's considered for 'additionalProperties'. Also, sometimes there
are bus specific properties such as 'spi-max-frequency' that go into
bus child nodes, but aren't defined in the child node's schema.

So let's stick with the json-schema defined default and add
'additionalProperties: false' where needed. This will be a continual
review comment and game of wack-a-mole.
