   entries
 
 - Add various checks that expected strings are strings before accessing
   them
 
 - Drop redundant memset() when unflattening DT
 
 DT bindings:
 - Add a DTS style checker. Currently hooked up to dt_binding_check to
   check examples.

1589352a0c
dt-bindings: i2c: microchip,corei2c: permit resets
Both CoreI2C and the hardened versions of it on mpfs and pic64gx have a
reset pin. For the former, usually this is wired to a common fabric
reset not managed by software and for the latter two the platform
firmware takes them out of reset on first-party boards (or those using
modified versions of the vendor firmware), but not all boards may take
this approach. Permit providing a reset in devicetree for Linux, or
other devicetree-consuming software, to use.

Pull i2c updates from Wolfram Sang:
 "The biggest news in this pull request is that it will start the last
  cycle of me handling the I2C subsystem. From 7.2. on, I will pass
  maintainership to Andi Shyti who has been maintaining the I2C drivers
  for a while now and who has done a great job in doing so.

  We will use this cycle for a hopefully smooth transition. Thanks must
  go to Andi for stepping up! I will still be around for guidance.

  Updates:
   - generic cleanups in npcm7xx, qcom-cci, xiic and designware DT
     bindings
   - atr: use kzalloc_flex for alias pool allocation
   - ixp4xx: convert bindings to DT schema
   - ocores: use read_poll_timeout_atomic() for polling waits
   - qcom-geni: skip extra TX DMA TRE for single read messages
   - s3c24xx: validate SMBus block length before using it
   - spacemit: refactor xfer path and add K1 PIO support
   - tegra: identify DVC and VI with SoC data variants
   - tegra: support SoC-specific register offsets
   - xiic: switch to devres and generic fw properties
   - xiic: skip input clock setup on non-OF systems
   - various minor improvements in other drivers

  rtl9300:
   - add per-SoC callbacks and clock support for RTL9607C
   - add support for new 50 kHz and 2.5 MHz bus speeds
   - general refactoring in preparation for RTL9607C support

  New support:
   - DesignWare GOOG5000 (ACPI HID)
   - Intel Nova Lake (ACPI ID)
   - Realtek RTL9607C
   - SpacemiT K3 binding
   - Tegra410 register layout support"

dt-bindings: i2c: realtek,rtl9301-i2c: extend for clocks and RTL9607C support
Add the "realtek,rtl9607-i2c" compatible for i2c controller on the
RTL9607C SoC series.

Add a clocks property to the properties to describe the i2c reference
clock and make it available for all the compatibles. This i2c reference
clock is assumed to be coming from switchcore region via Lexra bus as
the other SoC peripherals.

According to the info available about the existing devices, they also
have the i2c master controller clocks.

RTL9607C requires the "realtek,scl" and "clocks" to be specified
and so handle it under separate if check for "realtek,rtl9607-i2c".

6589b3d76d soc: devicetree updates for 7.0
There are a handful of new SoCs this time, all of these are
 more or less related to chips in a wider family:
 
  - SpacemiT Key Stone K3 is an 8-core risc-v chip, and the first
    widely available RVA23 implementation. Note that this is
    entirely unrelated with the similarly named Texas Instruments
    K3 chip family that follwed the TI Keystone2 SoC.
 
  - The Realtek Kent family of SoCs contains three chip models
    rtd1501s, rtd1861b and rtd1920s, and is related to their earlier
    Set-top-box and NAS products such as rtd1619, but is built
    on newer Arm Cortex-A78 cores.
 
  - The Qualcomm Milos family includes the Snapdragon 7s Gen 3
    (SM7635) mobile phone SoC built around Armv9 Kryo cores of the Arm
    Cortex-A720 generation. This one is used in the Fairphone Gen 6
 
  - Qualcomm Kaanapali is a new SoC based around eight high
    performance Oryon CPU cores
 
  - NXP i.MX8QP and i.MX952 are both feature reduced versions of
    chips we already support, i.e. the i.MX8QM and i.MX952, with
    fewer CPU cores and I/O interfaces.
 
 As part of a cleanup, a number of SoC specific devicetree files got
 removed because they did not have a single board using the .dtsi files
 and they were never compile tested as a result: Samsung s3c6400,
 ST spear320s, ST stm32mp21xc/stm32mp23xc/stm32mp25xc, Renesas
 r8a779m0/r8a779m2/r8a779m4/r8a779m6/r8a779m7/r8a779m8/r8a779mb/
 r9a07g044c1/r9a07g044l1/r9a07g054l1/r9a09g047e37, and TI am3703/am3715.
 All of these could be restored easily if a new board gets merged.
 
 Broadcom/Cavium/Marvell ThunderX2 gets removed along with its only
 machine, as all remaining users are assumed to be using ACPI
 based firmware.
 
 A relatively small number of 43 boards get added this time, and
 almost all of them for arm64. Aside from the reference boards for
 the newly added SoCs, this includes:
 
  - Three server boards use 32-bit ASpeed BMCs
 
  - One more reference board for 32-bit Microchip LAN9668
 
  - 64-bit Arm single-board computers based on Amlogic s905y4,
    CIX sky1, NXP ls1028a/imx8mn/imx8mp/imx91/imx93/imx95,
    Qualcomm qcs6490/qrb2210 and Rockchip rk3568/rk3588s
 
  - Carrier board for SOMs using Intel agilex5, Marvell Armada 7020,
    NXP iMX8QP, Mediatek mt8370/mt8390 and rockchip rk3588
 
  - Two mobile phones using Snapdragon 845
 
  - A gaming device and a NAS box, both based on Rockchips rk356x
 
 On top of the newly added boards and SoCs, there is a lot of
 background activity going into cleanups, in particular towards
 getting a warning-free dtc build, and the usual work on adding
 support for more hardware on the previously added machines.

  am3703/am3715. All of these could be restored easily if a new board
  gets merged.

  Broadcom/Cavium/Marvell ThunderX2 gets removed along with its only
  machine, as all remaining users are assumed to be using ACPI based
  firmware.

  A relatively small number of 43 boards get added this time, and almost
  all of them for arm64. Aside from the reference boards for the newly
  added SoCs, this includes:

   - Three server boards use 32-bit ASpeed BMCs

   - One more reference board for 32-bit Microchip LAN9668

   - 64-bit Arm single-board computers based on Amlogic s905y4, CIX
     sky1, NXP ls1028a/imx8mn/imx8mp/imx91/imx93/imx95, Qualcomm
     qcs6490/qrb2210 and Rockchip rk3568/rk3588s

   - Carrier board for SOMs using Intel agilex5, Marvell Armada 7020,
     NXP iMX8QP, Mediatek mt8370/mt8390 and rockchip rk3588

   - Two mobile phones using Snapdragon 845

   - A gaming device and a NAS box, both based on Rockchips rk356x

  On top of the newly added boards and SoCs, there is a lot of
  background activity going into cleanups, in particular towards getting
  a warning-free dtc build, and the usual work on adding support for
  more hardware on the previously added machines"

dt-bindings: i2c: Add CP2112 HID USB to SMBus Bridge
This is a USB HID device which includes an I2C controller and 8 GPIO pins.

The binding allows describing the chip's gpio and i2c controller in DT,
with the i2c controller being bound to a subnode named "i2c". This is
intended to be used in configurations where the CP2112 is permanently
connected in hardware.

6044a1ee9d Devicetree updates for v6.19:
DT bindings:
 - Convert lattice,ice40-fpga-mgr, apm,xgene-storm-dma, brcm,sr-thermal,
   amazon,al-thermal, brcm,ocotp, mt8173-mdp, Actions Owl SPS, Marvell
   AP80x System Controller, Marvell CP110 System Controller,
   cznic,moxtet, and apm,xgene-slimpro-mbox to DT schema format
 
 - Add i.MX95 fsl,irqsteer, MT8365 Mali Bifrost GPU, Anvo ANV32C81W
   EEPROM, and Microchip pic64gx PLIC
 
 - Add missing LGE, AMD Seattle, and APM X-Gene SoC platform compatibles
 
 - Updates to brcm,bcm2836-l1-intc, brcm,bcm2835-hvs, and bcm2711-hdmi
   bindings to fix warnings on BCM2712 platforms
 
 - Drop obsolete db8500-thermal.txt
 
 - Treewide clean-up of extra blank lines and inconsistent quoting
 
 - Ensure all .dtbo targets are applied to a base .dtb
 
 - Speed up dt_binding_check by skipping running validation on empty
   examples
 
 DT core:
 - Add of_machine_device_match() and of_machine_get_match_data() helpers
   and convert users treewide
 
 - Fix bounds checking of address properties in FDT code. Rework the code
   to have a single implementation of the bounds checks.
 
 - Rework of_irq_init() to ignore any implicit interrupt-parent (i.e. in
   a parent node) on nodes without an interrupt. This matches the spec
   description and fixes some RISC-V platforms.
