dt-bindings: Convert Reserved Memory binding to a schema

2021-09-13T13:20:18+00:00

Convert the reserved memory bindings to DT schema format. The bindings
are split into schemas for clients, common reserved memory node
properties and a specific binding for shared-dma-pool.

dt-bindings: of: Add restricted DMA pool

2021-07-14T00:04:52+00:00

Introduce the new compatible string, restricted-dma-pool, for restricted
DMA. One can specify the address and length of the restricted DMA memory
region by restricted-dma-pool in the reserved-memory node.

pstore: Add mem_type property DT parsing support

2021-03-31T17:06:23+00:00

There could be a scenario where we define some region
in normal memory and use them store to logs which is later
retrieved by bootloader during warm reset.

In this scenario, we wanted to treat this memory as normal
cacheable memory instead of default behaviour which
is an overhead. Making it cacheable could improve
performance.

This commit gives control to change mem_type from Device
tree, and also documents the value for normal memory.

The reusable and the no-map property are mutually exclusive.
Clarify this in the documentation.

Merge tag 'devicetree-for-5.8' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux

2020-06-05T03:11:25+00:00

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

 - Vendor prefixes for Protonic Holland, BeagleBoard.org, Alps, Check
   Point, Würth Elektronik, U-Boot, Vaisala, Baikal Electronics,
   Shanghai Awinic Technology Co., MikroTik, Silex Insight

 - A bunch more binding conversions to DT schema. Only 3K to go.

 - Add a minimum version check for schema tools

 - Treewide dropping of 'allOf' usage with schema references. Not needed
   in new json-schema spec.

 - Some formatting clean-ups of schemas

ramoops: Add "max-reason" optional field to ramoops DT node

2020-05-30T17:34:03+00:00

Currently, it is only possible to get kmsg dumps for panic and oops,
or just panic, via "no-dump-oops". With "max-reason" it is possible to
dump messages for other kmsg_dump events, for example emerg and shutdown.

dt-bindings: reserved-memory: Introduce memory-region-names

2020-04-15T16:23:30+00:00

In order to make the reserved-memory bindings more consistent with other
existing bindings, add a memory-region-names property that contains an
array of strings that name the entries of the memory-region property and
allows these regions to be looked up by name.
