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 Signed-off-by: Josua Mayer <josua@xxxxxxxxxxxxx> --- 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@xxxxxxxxxx>) - 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@xxxxxxxxxxxxx --- Josua Mayer (4): dt-bindings: arm: ti: Add bindings for SolidRun AM642 HummingBoard-T dt-bindings: rtc: abx80x: convert to yaml arm64: dts: add description for solidrun am642 som and evaluation board arm64: dts: ti: hummingboard-t: add descriptions for m.2 pci-e and usb-3 Suman Anna (1): arm64: dts: ti: k3-am64-main: Add ICSSG IEP nodes Documentation/devicetree/bindings/arm/ti/k3.yaml | 7 + .../devicetree/bindings/rtc/abracon,abx80x.txt | 31 - .../devicetree/bindings/rtc/abracon,abx80x.yaml | 56 ++ arch/arm64/boot/dts/ti/Makefile | 3 + arch/arm64/boot/dts/ti/k3-am64-main.dtsi | 24 + .../boot/dts/ti/k3-am642-hummingboard-t-pcie.dts | 31 + .../boot/dts/ti/k3-am642-hummingboard-t-usb3.dts | 37 ++ arch/arm64/boot/dts/ti/k3-am642-hummingboard-t.dts | 326 +++++++++++ arch/arm64/boot/dts/ti/k3-am642-sr-som.dtsi | 638 +++++++++++++++++++++ 9 files changed, 1122 insertions(+), 31 deletions(-) --- base-commit: 861deac3b092f37b2c5e6871732f3e11486f7082 change-id: 20240101-add-am64-som-51a1ca47edf3 Sincerely, -- Josua Mayer <josua@xxxxxxxxxxxxx>
