e465ea5cc0 dt-bindings: soc: samsung: usi: refer to dtschema for children
Explicitly reference the dtschema for USI children implementing specific
serial protocol (I2C, SPI, UART).  The SPI schema is not yet accepted,
so it will be provided later.

39bd2b6a37 dt-bindings: Improve phandle-array schemas
The 'phandle-array' type is a bit ambiguous. It can be either just an
array of phandles or an array of phandles plus args. Many schemas for
phandle-array properties aren't clear in the schema which case applies
though the description usually describes it.

The array of phandles case boils down to needing:

items:
  maxItems: 1

The phandle plus args cases should typically take this form:

items:
  - items:
      - description: A phandle
      - description: 1st arg cell
      - description: 2nd arg cell

With this change, some examples need updating so that the bracketing of
property values matches the schema.

aca48b2dd1 ARM: SoC devicetree changes for v5.17
As usual, this is the bulk of the updates for the SoC tree, adding
 more devices to existing files, addressing issues from ever improving
 automated checking, and fixing minor issues.
 
 The most interesting bits as usual are the new platforms.
 All the newly supported SoCs belong into existing families
 this time:
 
  - Qualcomm gets support for two newly announced platforms, both
    of which can now work in production environments: the SDX65
    5G modem that can run a minimal Linux on its Cortex-A7 core,
    and the Snapdragon 8 Gen 1, their latest high-end phone SoC.
 
  - Renesas adds support for R-Car S4-8, the most recent automotive
    Server/Communication SoC.
 
  - TI adds support for J721s2, a new automotive SoC in the K3
    family.
 
  - Mediatek MT7986a/b is a SoC used in Wifi routers, the latest
    generation following their popular MT76xx series. Only basic
    support is added for now.
 
  - NXP i.MX8 ULP8 is a new low-power variant of the widespread
    i.MX8 series.
 
  - TI SPEAr320s is a minor variant of the old SPEAr320 SoC that
    we have supported for a long time.
 
 New boards with the existing SoCs include
 
  - Aspeed AST2500/AST2600 BMCs in TYAN, Facebook and Yadro servers
 
  - AT91/SAMA5 based evaluation board
 
  - NXP gains twenty new development and industrial boards for their
    i.MX and Layerscape SoCs
 
  - Intel IXP4xx now supports the final two machines in device tree
    that were previously only supported in old style board files.
 
  - Mediatek MT6589 is used in the Fairphone FP1 phone from 2013,
    while MT8183 is used in the Acer Chromebook 314.
 
  - Qualcomm gains support for the reference machines using the two
    new SoCs, plus a number of Chromebook variants and phones based
    on the Snapdragon 7c, 845 and 888 SoCs, including various
    Sony Xperia devices and the Microsoft Surface Duo 2.
 
  - ST STM32 now supports the Engicam i.Core STM32MP1 carrier board.
 
  - Tegra now boots various older Android devices based on 32-bit
    chips out of the box, including a number of ASUS Transformer
    tablets.
    There is also a new Jetson AGX Orin developer kit.
 
  - Apple support adds the missing device trees for all the remaining
    M1 Macbook and iMac variants, though not yet the M1 Pro/Max
    versions.
 
  - Allwinner now supports another version of the Tanix TX6 set-top
    box based on the H6 SoC.
 
  - Broadcom gains support for the Netgear RAXE500 Wireless router
    based on BCM4908.

96c8bddb6c dt-bindings: soc: samsung: keep SoC driver bindings together
Recently added Samsung Exynos USI driver devicetree bindings were added
under ../bindings/soc/samsung/exynos-usi.yaml, so move there also two
other bindings for Exynos SoC drivers: the PMU and ChipID.

Update Samsung Exynos MAINTAINERS entry to include this new path.

d56a8e9c7a dt-bindings: soc: samsung: Fix I2C clocks order in USI binding example
Now that HSI2C binding [1] is converted to dt-schema format, it reveals
incorrect HSI2C clocks order in USI binding example:

    .../exynos-usi.example.dt.yaml:
    i2c@13820000: clock-names:0: 'hsi2c' was expected
    From schema: .../i2c-exynos5.yaml

    .../exynos-usi.example.dt.yaml:
    i2c@13820000: clock-names:1: 'hsi2c_pclk' was expected
    From schema: .../i2c-exynos5.yaml

Change HSI2C clock order in USI binding example to satisfy HSI2C binding
requirements and fix above warnings.
