Merge tag 'devicetree-for-5.13' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux

2021-04-28T22:50:24+00:00

Pull devicetree updates from Rob Herring:

 - Refactor powerpc and arm64 kexec DT handling to common code. This
   enables IMA on arm64.

 - Add kbuild support for applying DT overlays at build time. The first
   user are the DT unittests.

 - Fix kerneldoc formatting and W=1 warnings in drivers/of/

 - Fix handling 64-bit flag on PCI resources

 - Bump dtschema version required to v2021.2.1

 - Enable undocumented compatible checks for dtbs_check. This allows
   tracking of missing binding schemas.

 - DT docs improvements. Regroup the DT docs and add the example schema
   and DT kernel ABI docs to the doc build.

 - Convert Broadcom Bluetooth and video-mux bindings to schema

 - Add QCom sm8250 Venus video codec binding schema

 - Add vendor prefixes for AESOP, YIC System Co., Ltd, and Siliconfile
   Technologies Inc.

 - Cleanup of DT schema type references on common properties and
   standard unit properties

dt-bindings: usb: mtk-xhci: remove redefinitions of usb3-lpm-capable

2021-04-02T13:56:49+00:00

The property usb3-lpm-capable is defined in usb-xhci.yaml which is
already referenced in this file, so no need 'description' and 'type'
anymore.

dt-bindings: usb: dwc3-imx8mp: Use the correct name for child node "snps, dwc3"

2021-04-02T13:21:41+00:00

File snps,dwc3.yaml describes the schema of Synopsys DesignWare USB3
Controller, it directly or indirectly contains "$ref: usb.yaml". So the
node name of "snps,dwc3" must start with "usb". Otherwise, the following
warning will be displayed:

Documentation/devicetree/bindings/usb/fsl,imx8mp-dwc3.example.dt.yaml: \
dwc3@38100000: $nodename:0: 'dwc3@38100000' does not match '^usb(@.*)?'
        From schema: Documentation/devicetree/bindings/usb/snps,dwc3.yaml

In addition, replace "type: object" with "$ref: snps,dwc3.yaml#". Ensure
that all properties of the child node comply with snps,dwc3.yaml.

dt-bindings: usb: mediatek,mtu3: Use graph schema

2021-03-28T11:43:34+00:00

Users of the DT graph binding now should reference it for their 'port'
schemas, so add it for Mediatek MTU3 binding.

dt-bindings: usb: mtu3: support wakeup for mt8183 and mt8192

2021-03-28T11:42:23+00:00

These two HW of wakeup don't follow MediaTek internal IPM rule,
and both use a specific way, like as early revision of mt8173.

Due to the index 2 already used by many DTS, it's better to keep
it unchanged for backward compatibility, treat specific ones without
following IPM rule as revision 1.x, meanwhile reserve 3~99 for
later revision that following the IPM rule.
