v2 cover arm64: dts: rockchip: Add support for Axelera Embedded 111c
The Axelera Embedded 111c is an SBC based on the Rockchip RK3588 SoC. It offers efficient AI compute for multi-stream computer vision and generative AI applications in a compact design.
Product page [1].
This series aims to introduce basic support for the board, which includes the console, the eMMC, the two Gigabit Ethernet ports, the four USB ports and the HDMI connector.
Changes in v2:
- The board was renamed by Axelera between v1 and v2, from "Metis Compute Board" to "Embedded 111c". Address the name change. Drop Conor's Acked-by on the bindings, since the compatible changed. Keep it on the vendor-prefix.
- Address Heiko's comment about regulator node names starting with "regulator-".
- Address Heiko's comment about non-existent "mem-supply" binding.
- Address Heiko's comment about dropping the unneeded "Use rgmii-rxid mode to disable rx delay inside Soc" comment; checkpatch complains about uncommented rgmii-rxid, so take the one from rk3588-youyeetoo-yy3588.
- Address Heiko's comment about reset lines of the phy nodes being incorrectly described in the gmac node; note that these are still not described in the phy node because GPIO3_B7 defaults to pull-down, which causes the rgmii_phy1 node to never come up; rgmii_phy0's reset GPIO, GPIO4_B3, defaults to pull-up, so that node does not encounter the same issue. Moving the reset to the parent mdio node instead did the trick.
- Address Sashiko's high severity comment about hdmi0 node mixing M0 and M1 pinmux groups; use the existing hdmim1_tx0_hpd pinctrl group instead of redefining it. HPD is wired to M1 while CEC and DDC use the M0 pins. Verified hot-plug detection on external display.
- Address Sashiko's medium comment about "full-pwr-cycle-in-suspend" and missing "vmmc-supply" and "vqmmc-supply" on the eMMC node; drop the former, add the latter two.
- Address Sashiko's medium comment about the pmic node lacking a pinctrl assignment for the interrupt pin; add it.
- Address Sashiko's medium comment about the "vcc3v3_hubreset" regulator hack; describe the two GL3523 hubs linked with peer-hub.
- Address Sashiko's low comment about defined-but-never-referenced regulators without regulator-always-on property; drop them, alongside their pinctrls.
- Mux PCIEX4_PERST_N as GPIO, to match it being used via reset-gpios.
- Drop the unused input.h include.
- Drop the unused rtc label.
- Drop the local PCIe x1 pinctrl groups, which duplicated the pcie30x1m1_1_* groups in rk3588-base-pinctrl.dtsi.

PATCH v2 3/3 arm64: dts: rockchip: Add Axelera Embedded 111c
In reply to Patrick BarsantiAdd minimal device tree for the Axelera Embedded 111c (rk3588-embedded-111c).
It offers efficient AI compute for multi-stream computer vision and GenAI applications in a compact design. It features a quad-core Axelera AI Metis AIPU and an RK3588 SoC processor.
This basic version of the dts supports:
- Console
- eMMC
- HDMI
- 4x USB-A
- 2x Gigabit Ethernet
- RTC
- Enumeration of on-board Axelera Metis AIPU
---
Changes in v2:
- Prepend "regulator-" to regulator nodes
- Drop non-existent "mem-supply" binding
- Drop unneeded comment from rgmii-rxid; replace it with the one from rk3588-youyeetoo-yy3588 to stop checkpatch from complaining
- Remove phy reset from the gmac node; note that these are still not described in the phy node because GPIO3_B7 defaults to pull-down, which causes the rgmii_phy1 node to never come up. Describing the reset in the parent mdio node instead does not cause the same issue
- Use the existing hdmim1_tx0_hpd pinctrl group instead of redefining it
- Drop "full-pwr-cycle-in-suspend" from the eMMC node
- Add "vmmc-supply" and "vqmmc-supply" to the eMMC node
- Add pinctrl for the pmic interrupt pin
- Replace the "vcc3v3_hubreset" regulator hack with two GL3523 hubs linked with "peer-hub".
- Drop the regulators that were defined but never referenced, and their corresponding pinctrls
- Mux PCIEX4_PERST_N as GPIO, since it is being used as reset-gpios
- Drop unused input.h include
- Drop unused rtc label
- Drop the local pciex1 pinctrl groups, as they were duplicates of the pcie30x1m1_1_* groups in the base pinctrl for the rk3588

[Severity: Low]
The v2 changelog mentions dropping regulators that were defined but never referenced along with their corresponding pinctrls.
However, vcc3v3_m2, its parent supply vcc3v3_sus, and the four pcie20_avdd0v85, pcie20_avdd1v8, pcie30_avdd0v75, and pcie30_avdd1v8 regulators are not referenced anywhere in rk3588-embedded-111c.dts (the only enabled PCIe controller is &pcie3x4, which uses vpcie3v3-supply = <&vcc_1v8_pcie>).
Because vcc3v3_m2 specifies regulator-always-on and regulator-boot-on, the fixed-regulator driver will still claim gpio0 RK_PC4 (using pinctrl pcie_pwren_h) and drive it high at boot even though no M.2 PCIe controller is enabled.
Should vcc3v3_m2 (along with pcie_pwren_h and vcc3v3_sus) and the unreferenced pcie20/pcie30 avdd regulators be dropped as well?

[Severity: Low]
Will make dtbs_check fail to match the rgmii_phy0 and rgmii_phy1 nodes against Documentation/devicetree/bindings/net/ethernet-phy.yaml?
In Documentation/devicetree/bindings/net/ethernet-phy.yaml, the select block only matches nodes whose name matches "^ethernet-phy(@[a-f0-9]+)?$":
select:
properties:
$nodename:
pattern: "^ethernet-phy(@[a-f0-9]+)?$" required:
- $nodename
Because the nodes under &mdio0 and &mdio1 are named phy@1 and phy@3 with compatible = "ethernet-phy-ieee802.3-c22", dtbs_check reports that no schema matches that compatible string. Should these nodes be named ethernet-phy@1 and ethernet-phy@3 instead?

It's a bit complicated; let's say the core was done by us in a workshop and even I'm
the original author of the first version of this board's support in downstream. I think that co-development is more appropriate for me and Dario. Anyway not being here is not a big deal for me, because I don't spend time on the series at the end
