Subject[PATCH v2 0/5] arm64: dts: add description for solidrun am642 som and hummingboard evb
Date
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.

- icssg1-eth dmas is too long
It is caused by definint 12 dmas, when ti,icssg-prueth.yaml specifies a
maximum of 10. The pru ethernet on am64 mostly identical to am65 - see
e.g. arch/arm64/boot/dts/ti/k3-am654-idk.dtso which also defines 12 dma.
I cannot fix it because unsure what is the purpose of last two dmas.

- 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 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
