[v4,0/5] arm64: dts: add description for solidrun am642 som and hummingboard evb

  This series adds DT bindings and dts descriptions for SolidRun AM642
based SoM and Hummingboard EVB.

Additionally a commit from downstream vendor kernel are included,
enhancing support for pru based ethernet.
I wasn't sure how to properly annotate it in commit description /
signed-off area ...:

1. add description for "Industrial Ethernet Peripherals" (IEP) to am64
   https://git.ti.com/cgit/ti-linux-kernel/ti-linux-kernel/commit/arch/arm64/boot/dts/ti/k3-am64-main.dtsi?h=ti-linux-6.1.y-cicd&id=5afb73d82a014b59462162d960b350b8c58e5ae6
   IEP is already supported in-tree by a driver, and used in
   k3-am65-main.dtsi.

Unfortunately dtbs_check reported many problems, I put some remarks:

- 'mux-controller' does not match any of the regexes
  The expectation seems to be that a mux-controller at minimum has an
  address, something to put behind an @. However this is a gpio mux, not
  sure how to name it better.

- unevaluated properties: interrupts, interrupt-parent
  sensors and flash yaml are missing interrupt descriptions, but these
  parts definitely have an interrupt signal in this solidrun board.

- wrong names for pinctrl nodes
  Other TI DTSs consistently end with *-pins-default. Should a different
  naming convention be used?

- cdns,phy-type required property
  inherited from k3-am64-main.dtsi
  there is a PHY_NONE value in dt-bindings/phy/phy.h,
  but not allowed in phy-cadence-torrent.yaml

Changes in v4:
- abracon,abx80x.yaml: fixed dtc error in example irq reference
- Link to v3: https://lore.kernel.org/r/20240202-add-am64-som-v3-0-2f44023d50e9@solid-run.com

Changes in v3:
- removed lots more status properties, double-checked against soc dtsi
  (reported by Krzysztof Kozlowski <krzysztof.kozlowski+dt@linaro.org>)
  (reported by Andrew Davis <afd@ti.com>)
- removed intentionally-disabled pcie node from dts
- rewrote yaml bindings to use enum instead of anyof+const+description
  (reported by Krzysztof Kozlowski <krzysztof.kozlowski+dt@linaro.org>)
- abracon yaml
  - added missing maintainer
  - added diode type property type
  - added example
  (reported by Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org>)
  - added reference to /schemas/interrupts.yaml#
- use generic name for pru ethernet controller node
  (reported by Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org>)
- removed unnamed dmas from pru ethernet controller node
- moved pcie/usb3 features to dtb overlays
- Link to v2: https://lore.kernel.org/r/20240112-add-am64-som-v2-0-1385246c428c@solid-run.com

Changes in v2:
- reordered patchset to drop separate patch adding iep handle to som
- moved dtbs_check warnings to cover letter
- converted abracon abx80x rtc bindings to yaml
- updated dts:
  - remove unnecessary status properties
  - changed non-generic node names
  - use color property for led descriptions,
    they have no default function on evaluation board
  - drop earlycon bootargs from chosen node
  (reported by Krzysztof Kozlowski <krzysztof.kozlowski+dt@linaro.org>)
- converted charger node to comment, part not assembled, has no bindings
- picked up acked-by on board bindings patch
- Link to v1: https://lore.kernel.org/r/20240103-add-am64-som-v1-0-dda1f9227aef@solid-run.com

it probably needs to be enabled here too.
