Pull i2c updates from Wolfram Sang:
 "I2C has largely driver updates for 6.7, i.e. feature additions (like
  adding transfers while in atomic mode), using new helpers (like
  devm_clk_get_enabled), new IDs, documentation fixes and additions...
  you name it.

  The core got a memleak fix and better support for nested muxes"

dt-bindings: eeprom: at24: allow NVMEM cells based on old syntax

2023-10-27T11:17:58+00:00

This binding supported NVMEM cells as subnodes and that syntax is used
by few in-kenel DTS files. Modify binding to allow it.

dt-bindings: at24: add ST M24C64-D Additional Write lockable page

2023-10-16T06:49:00+00:00

The ST M24C64-D behaves as a regular M24C64, except for the -D variant
which uses up another I2C address for Additional Write lockable page.
This page is 32 Bytes long and can contain additional data. Document
compatible string for it, so users can describe that page in DT. Note
that users still have to describe the main M24C64 area separately as
that is on separate I2C address from this page.

Pull devicetree updates from Rob Herring:
 "DT core:

   - Add support for generating DT nodes for PCI devices. This is the
     groundwork for applying overlays to PCI devices containing
     non-discoverable downstream devices.

   - DT unittest additions to check reverted changesets, to test for
     refcount issues, and to test unresolved symbols. Also, various
     clean-ups of the unittest along the way.

   - Refactor node and property manipulation functions to better share
     code with old API and changeset API

   - Refactor changeset print functions to a common implementation

   - Move some platform_device specific functions into of_platform.c

  Bindings:

   - Treewide fixing of typos

   - Treewide clean-up of SPDX tags to use 'OR' consistently

   - Last chunk of dropping unnecessary quotes. With that, the check for
     unnecessary quotes is enabled in yamllint.

   - Convert ftgmac100, zynqmp-genpd, pps-gpio, syna,rmi4, and qcom,ssbi
     bindings to DT schema format

   - Add Allwinner V3s xHCI USB, Saef SF-TC154B display, QCom SM8450
     Inline Crypto Engine, QCom SM6115 UFS, QCom SDM670 PDC interrupt
     controller, Arm 2022 Cortex cores, and QCom IPQ9574 Crypto bindings

   - Fixes for Rockchip DWC PCI binding

   - Ensure all properties are evaluated on USB connector schema

   - Fix dt-check-compatible script to find of_device_id instances with
     compiler annotations"

dt-bindings: Fix SPI and I2C bus node names in examples

2023-03-08T15:04:53+00:00

SPI and I2C bus node names are expected to be "spi" or "i2c",
respectively, with nothing else, a unit-address, or a '-N' index. A
pattern of 'spi0' or 'i2c0' or similar has crept in. Fix all these
cases. Mostly scripted with the following commands:

git grep -l '\si2c[0-9] {' Documentation/devicetree/ | xargs sed -i -e 's/i2c[0-9] {/i2c {/'
git grep -l '\sspi[0-9] {' Documentation/devicetree/ | xargs sed -i -e 's/spi[0-9] {/spi {/'

With this, a few errors in examples were exposed and fixed.

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

it is a "Devicetree binding", but instead just describe the hardware.

trailing full stop):
