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: fastrpc: Document memory-region property

2022-09-12T17:09:51+00:00

Add memory-region property to the list of optional properties, specify
the value type and a definition. This property is used to specify the
memory region which should be used for remote heap CMA.

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.

The children of FastRPC have either one or two IOMMUs in existing DTS
(SM8150, SM8450 and others).

qcom,nsessions.

dt-bindings: misc: fastrpc convert bindings to yaml

2022-09-07T15:42:24+00:00

Convert Qualcomm FastRPC bindings to yaml format, so that we could validate
dt-entries correctly and any future additions can go into yaml format.

Use compute-cb@ subnodes instead of just cb@. Add qcom,glink-channels and
qcom,smd-channels missing properties to make sure dtbs_check doesn't fail
right off the bat. Correct the name of the parent node in the example from
smd-edge to glink-edge.

Since now the qcom,fastrpc bindings document is yaml, update the
reference to it in qcom,glink-edge and also use $ref.

Also update the MAINTAINERS file to point to the yaml version.
