Jarkko does now work for Intel anymore and since I'm currently
maintaining this driver, update my contact information here to make sure
patches get Cc'd to me as well.

6589b3d76d Merge tag 'soc-dt-7.0' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc
Pull SoC devicetree updates from Arnd Bergmann:
 "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"

079a015b5a 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.

Adjust the regex for child-node address to account for the fact that

Add a vendor-specific property to explicitly specify the SCL line number
of the defined I2C controller/master. This is required, in particular
for RTL9310, to operate on the correct SCL for each controller. Require
this property to be specified for RTL9310.

Add compatibles for known SoC variants RTL9311, RTL9312 and RTL9313.

Pull SoC dt updates from Arnd Bergmann:
 "There are five sets of new SoCs that get added in existing families,
  all of them being either upgrades or cut-down versions of the older
  chips:

   - Apple M2 Pro, M2 Max and M2 Ultra, used in the 2022/2023 generation
     of high-end workstations and laptops from Apple. Linux has been
     working on these for a while but stil requires patches.

   - Axis Artpec8 is an Armv8 chip based on Samsung Exynos design,
     unlike the earlier Armv7 Artpec6 from the same company that was
     part of a separate family of chips.

   - NXP i.MX91 is a cut-down version of i.MX93, using only a single
     Cortex-A55 core.

   - Qualcomm Lemans Auto is a variant of the Lemans SoC that was
     originally merged under the sa8775p name, the differences being
     mostly the firmware configuration of the platform.

   - Four new Renesas SoCs RZ/T2H (r9a09g077m44), RZ/N2H (r9a09g087m44),
     RZ/T2H (r9a09g077), and RZ/N2H (r9a09g087) are all industrial
     bedded SoCs based on Cortex-A55 cores

  In total, there are 65 new machines, including:

   - Industrial embedded system and single-board computers based on NXP,
     Allwinner, TI, Rockchips, Marvell, Xilinx Spacemit, Starfive chips.

   - Reference boards for the newly added Renesas, Qualcomm, NXP and
     Axis ARMv8 chips as well as Microchip's MPFS RISC-V SoC

   - Laptops and Workstations using Apple M2 and Qualcomm Snapdragon X1
     chips.

   - Several Samsung phones using Qualcomm Snapdragon chips

   - Set-top boxes based on Allwinner H313

   - Five BMC boards using 32-bit ASpeed SoCs

   - Three network routers using IXP4xx (ARMv5!) and Broadcom bcm4708
     (ARMv7) SoCs

  Two machines get phased out because they were available only in small
  quantities but never made it into products: one STi407 based reference
  board, and a Snapdragon 845 based Chromebook.

  Aside from the newly added machines, a lot of work went into improving
  hardware support on the existing machines and cleaning up contents for
  validation"

69329daf16 dt-bindings: i2c: nvidia,tegra20-i2c: Add Tegra256 I2C compatible
Add compatible for Tegra256 I2C controllers. Tegra256 consists of
8 generic Tegra I2C controllers similar to previous generations.
The parent clock frequency is different in these controllers and
hence the timing parameter values are different from the previous
ones.

f77a13df57 dt-bindings: i2c: apple,i2c: Add apple,t6020-i2c compatible
After discussion with the devicetree maintainers we agreed to not extend
lists with the generic compatible "apple,i2c" anymore [1]. Use
"apple,t8103-i2c" as fallback compatible as it is the SoC the driver
and bindings were written for.

This block is compatible with t8103, so just add the new per-SoC
compatible using apple,t8103-i2c as base.

Tegra264 has 17 generic I2C controllers, two of which are in always-on
partition of the SoC. In addition to the features supported by Tegra194
it also supports a SW mutex register to allow sharing the same I2C
instance across multiple firmware.

Document compatible string "nvidia,tegra264-i2c" for Tegra264 I2C.

aa1826696a dt-bindings: media: Deprecate clock-frequency property for camera sensors
Usage of the clock-frequency property for camera sensors is discouraged
in favour of using assigned-clock-rates (and assigned-clock-parents
where needed). Mark the property as deprecated.

Update the examples accordingly. In DT examples where the sensor input
clock appears to come from a programmable clock generator, replace
clock-frequency by the assigned-clocks and assigned-clock-rates
properties. Otherwise, just drop clock-frequency.

f8fd855d5b dt-bindings: i2c: i2c-rk3x: Allow use of a power-domain
The I2C controllers in most Rockchip SoCs are part of power domains that
are always powered on, i.e. PD_BUS or PD_PMU. These always powered
on power domains have typically not been described in the device tree.

Because these power domains have been left out of the device tree there
has not been any real need to properly describe the I2C controllers
power domain.

On RK3528 the I2C controllers are spread out among the described
PD_RKVENC, PD_VO and PD_VPU power domains. However, one I2C controller
belong to an undescribed always powered on power domain.

Add support to describe an optional power-domains for the I2C
controllers in Rockchip SoCs.
