dt-bindings: misc: tmr-inject: Add device-tree binding for TMR Inject

2023-01-20T12:09:31+00:00

The Triple Modular Redundancy(TMR) Inject core provides functional fault
injection by changing selected MicroBlaze instructions, which provides the
possibility to verify that the TMR subsystem error detection and fault
recovery logic is working properly.

dt-bindings: misc: tmr-manager: Add device-tree binding for TMR Manager

2023-01-20T12:08:52+00:00

Triple Modular Redundancy(TMR) subsystem contains three microblaze cores,
subsystem is fault-tolerant and continues to operate nominally after
encountering an error. Together with the capability to detect and recover
from errors, the implementation ensures the reliability of the entire
subsystem.  TMR Manager is responsible for performing recovery of the
subsystem detects the fault via a break signal it invokes microblaze
software break handler which calls the tmr manager driver api to
update the error count and status.

dt-bindings: drop redundant part of title (end, part three)

2022-12-16T17:41:49+00:00

The Devicetree bindings document does not have to say in the title that
it is a "binding", but instead just describe the hardware.

Drop trailing "bindings" in various forms (also with trailing full
stop):

  find Documentation/devicetree/bindings/ -type f -name '*.yaml' \
    -not -name 'trivial-devices.yaml' \
    -exec sed -i -e 's/^title: \(.*\) [bB]indings\?\.\?$/title: \1/' {} \;

Merge tag 'char-misc-6.2-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc

2022-12-16T11:49:24+00:00

Pull char/misc driver updates from Greg KH:
 "Here is the large set of char/misc and other driver subsystem changes
  for 6.2-rc1. Nothing earth-shattering in here at all, just a lot of
  new driver development and minor fixes.

  Highlights include:

   - fastrpc driver updates

   - iio new drivers and updates

   - habanalabs driver updates for new hardware and features

   - slimbus driver updates

   - speakup module parameters added to aid in boot time configuration

   - i2c probe_new conversions for lots of different drivers

   - other small driver fixes and additions

  One semi-interesting change in here is the increase of the number of
  misc dynamic minors available to 1048448 to handle new huge-cpu
  systems.

  All of these have been in linux-next for a while with no reported
  problems"

dt-bindings: misc: qcom,fastrpc: increase allowed iommus entries

2022-11-25T17:45:33+00:00

The fastrpc components on the SM8550 SoC can require up to 3 IOMMU
entries, this bumps the maxItems to 3 for this purpose.

dt-bindings: misc: Convert IDT 89HPESx to DT schema

2022-10-18T15:03:45+00:00

Convert the IDT 89HPESx device binding to DT schema format.

"onsemi,24c64" was not a documented compatible string, so update the
example to "atmel,24c64". It's not clear what's in use here as no
upstream dts files have the eeprom child node.

dt-bindings: misc: qcom,fastrpc: correct example for GLINK edge

2022-09-09T16:23:30+00:00

The parent of FastRPC node is GLINK edge, so the properties should be
matching GLINK, not SMD.  Correct the example and extend it based on
SM8350.
