Merge tag 'devicetree-for-5.7' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux

2020-04-03T00:32:52+00:00

Pull devicetree updates from Rob Herring:

 - Unit test for overlays with GPIO hogs

 - Improve dma-ranges parsing to handle dma-ranges with multiple entries

 - Update dtc to upstream version v1.6.0-2-g87a656ae5ff9

 - Improve overlay error reporting

 - Device link support for power-domains and hwlocks bindings

 - Add vendor prefixes for Beacon, Topwise, ENE, Dell, SG Micro, Elida,
   PocketBook, Xiaomi, Linutronix, OzzMaker, Waveshare Electronics, and
   ITE Tech

 - Add deprecated Marvell vendor prefix 'mrvl'

 - A bunch of binding conversions to DT schema continues. Of note, the
   common serial and USB connector bindings are converted.

 - Add more Arm CPU compatibles

 - Drop Mark Rutland as DT maintainer :(

dt-bindings: serial: sh-sci: Convert to json-schema

2020-03-31T21:28:56+00:00

Convert the Renesas Serial Communication Interface ((H)SCI(F)(A|B))
Device Tree binding documentation to json-schema.

Split the bindings in 5 files, one per major type, to ease expressing
constraints.

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.

dt-bindings: serial: snps-dw-apb-uart: add compatible property for rk3308 uart

2020-03-10T19:32:48+00:00

A test with the command below gives these errors:

arch/arm64/boot/dts/rockchip/rk3308-evb.dt.yaml: serial@ff0d0000: compatible:
['rockchip,rk3308-uart', 'snps,dw-apb-uart']

['rockchip,rk3308-uart', 'snps,dw-apb-uart']
is not valid under any of the given schemas

The compatible property for the Rockchip rk3308 uart was somehow never
added to the documention. Fix this error by adding 'rockchip,rk3308-uart'
to snps-dw-apb-uart.yaml.
