[PATCH v7 0/4] arm64: dts: add description for solidrun am642 som and hummingboard evb

[Josua Mayer <josua@solid-run.com>]

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.

To avoid introducing new dtbs_check errors, respective patches were
submitted via rtc, mtd and iio trees.

Only one error remains which is common to all k3-am64:

- 'mux-controller' does not match any of the regexes
