The easiest fix in most cases is to change the 'reg' property to 1 cell for address and size.

2020-05-03dt-bindings: Remove cases of 'allOf' containing a '$ref'Rob Herring
json-schema versions draft7 and earlier have a weird behavior in that any keywords combined with a '$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.

2020-03-31dt-bindings: Add missing 'additionalProperties: false'Rob Herring
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.

2018-12-21dt-bindings: tegra186-hsp: Add shared mailboxesMikko Perttunen
Shared mailboxes are a mechanism to transport data from one processor in the system to another. They are bidirectional links with both a producer and a consumer. Interrupts are used to let the consumer know when data was written to the mailbox by the producer, and to let the producer know when the consumer has read the data from the mailbox. These interrupts are mapped to one or more "shared interrupts". Typically each processor in the system owns one of these shared interrupts. Add documentation to the device tree bindings about how clients can use mailbox specifiers to request a specific shared mailbox and select which direction they drive. Also document how to specify the shared interrupts in addition to the existing doorbell interrupt.

2018-08-03dt-bindings: mailbox: Add support for secure proxy threadsNishanth Menon
Secure Proxy is another communication scheme in Texas Instrument's devices intended to provide an unique communication path from various processors in the System on Chip(SoC) to a central System Controller. Secure proxy is, in effect, an evolution of current generation Message Manager hardware block found in K2G devices. However the following changes have taken place: Secure Proxy instance exposes "threads" or "proxies" which is primary representation of "a" communication channel. Each thread is preconfigured by System controller configuration based on SoC usage requirements. Secure proxy by itself represents a single "queue" of communication but allows the proxies to be independently operated. Each Secure proxy thread can uniquely have their own error and threshold interrupts allowing for more fine control of IRQ handling. Provide an hardware description of the same for device tree representation.

2018-07-25dt-bindings: remove 'interrupt-parent' from bindingsRob Herring
'interrupt-parent' is often documented as part of define bindings, but it is really outside the scope of a device binding. It's never required in a given node as it is often inherited from a parent node. Or it can be implicit if a parent node is an 'interrupt-controller' node. So remove it from all the binding files.

2018-02-28dt-bindings: mailbox: add support for mailbox client shared memorySudeep Holla
Many users of the mailbox controllers depend on the shared memory between the two end points to exchange the main data while using simple doorbell mechanism to alert the end points of the presence of a message. This patch defines device tree bindings to represent such shared memory in a generic way.

Remove the relation to proxy ID in the documentation of binding. Existing device tree descriptions follow the correct conventions already and documentation update has been missed.
