… tree, supplies and suspend Rename rk3588-blade3-v101-linux.dts to rk3588-mixtile-blade3.dts and drop the PCB revision from the board identity. The file describes the Blade 3 as a product, not one PCB spin: model "Mixtile Blade 3 v1.0.1" -> "Mixtile Blade 3" compatible "rockchip,rk3588-blade3-v101-linux" -> "mixtile,blade3" The DTB name changes with it. armbian/build still points the vendor branch at rockchip/rk3588-blade3-v101-linux.dtb in config/boards/mixtile-blade3.csc and needs a matching update; its edge branch already uses rockchip/rk3588-mixtile-blade3.dtb. The rest is a review of the file against the Blade 3 schematic rev V1.1.0. Power tree. The board takes a 12-20V PD/barrel input rather than a fixed 12V rail, and the RK806 and the three RK860x are fed from the 4.0V buck, not from VCC5V0_SYS. Add vin_12_20v and vcc4v0_sys and repoint the consumers, including the RK806 vcc1..vcc10, vcc12 and vcca inputs, which had no supply at all. Drop vcc5v0_usbdcin and vcc5v0_usb, which described rails the board does not have, and the four pcie*_avdd* fixed regulators, which duplicated PMIC outputs and had no consumer. Add vcc3v3_minipcie on GPIO3_C6 and give pcie2x1l1 a vpcie3v3-supply. vcc_3v3_sd_s0 is enabled by a low level on GPIO0_B7 but carried enable-active-high and no voltage constraints; fix the polarity and add the constraints, the startup delay and the vcc_3v3_s3 parent. Supplies. Add venc-supply and mem-supply to rkvenc0 and rkvenc1 and vop-supply to vop. Without them rockchip_init_opp_table() finds no regulator through regulator_get_optional(), so no OPP table is built and both blocks stay at their boot voltage. saradc takes its reference from AVCC_1V8_S0, not VCC_1V8_S0. Memory. The cma node pinned the 256MB pool at a fixed address through reg; use size and let the allocator place it. Buses and peripherals. J7 routes i2c3 with external pull-ups; add it with a matching pinctrl group. Add i2c7 and i2c8. can2 has no transceiver on this board, and leaving it enabled only muxes two expansion-header pins away from GPIO, so disable it. Drop the i2s0_8ch node and the duplicate hdptxphy0 node. Use gpu_panthor. Make cec-enable the boolean it is rather than a string, and spell status = "disabled" correctly on the mini-PCIe USB3 combo nodes. Suspend. Replace the raw 0x4000024 with the RKPM_SLP_* macros. The board has no external 32.768kHz oscillator, so RKPM_SLP_32K_EXT must not be set; ARMOFF_DDRPD, PMU_PMUALIVE_32K and PMU_DIS_OSC remain. Rename the fan pinctrl groups to match the rest of the file and drop the unreferenced vcc5v0_host_en group and a commented-out pwrkey node. Also add a metadata node to the mixtile-blade3-sata2 overlay, so it shows up with a description in the overlay picker, and add a new mixtile-blade3-camera-imx415 overlay for the J7 FPC connector.

Review the Core3588E board file against the module schematic. The Core3588E is a Jetson-Nano-compatible SoM, so everything described here is on the module itself or on the pins it brings out on the 260-pin connector. Displays and audio. Add a dp-connector for the DP output carried on edp1 and wire it up through a new edp1 port@1, and add the rockchip-edp1-sound card fed from spdif_tx4. Rename the HDMI card to rockchip-hdmi0-sound to match. Add vcc_hdmi on GPIO0_C4, and move the HDMI HPD pin to hdmim1_tx0_hpd, which is the group the module routes. Storage. The SD card interface is wired 4-bit with no card-detect line, so use bus-width = <4> with the sdmmc_bus4 group, add broken-cd and drop the cd-gpios and the sdmmc_det group. Add no-sdio, no-mmc, cap-sd-highspeed and sd-uhs-sdr104 to describe what the slot supports. USB. The module brings out the second USB 3.1 controller, not the USB 2.0 host pair, so enable usbdrd3_1 and usbdrd_dwc3_1 and drop the u2phy3, u2phy3_host, usb_host1_ehci and usb_host1_ohci nodes. Suspend. Replace the raw 0x4000024 sleep-mode-config with the RKPM_SLP_* macros and add a wakeup-config of RKPM_GPIO_WKUP_EN and RKPM_CPU0_WKUP_EN. Keep vdd_log_s0 up across suspend by deleting the off-in-suspend and suspend-microvolt properties it inherits and setting regulator-on-in-suspend instead; the logic rail has to stay alive for the DDR to be self-refreshed with the PD off. Also: use gpu_panthor; take the saradc reference from AVCC_1V8_S0; give the SPI controller its second chip select and a spidev for each; replace the adc-keys node, which described keys this board does not have, with a recovery gpio-key, and add sys_status_led; drop pcie2x1l1, which is not routed on the module; and drop the hdmirx CMA reservation and the unused dt-bindings/usb/pd.h include. The two IMX219 camera overlays are the RPi camera v2 configurations for the CAM0 and CAM1 FPC connectors on the carrier. CAM0 is GPIO3_C4 PWDN with MIPI_CAM0_MCLK_M1 on GPIO3_A5 and the CSI0 lanes; CAM1 is GPIO3_C5 with MIPI_CAM1_MCLK_M1 on GPIO3_A6 and the CSI2 lanes.

…ings and drop unused audio Review the Edge 2 board file against the schematic and switch it to the board's real identity. Identity. The compatible still carried focalcrest,mixtile-edge2 from before the product was named; use mixtile,edge2. Add the missing SPDX line. WiFi and Bluetooth. Replace the Rockchip-specific wlan-platdata and bluetooth-platdata nodes with the standard bindings: an sdio_pwrseq for the WiFi side and a bluetooth child node on uart8 using brcm,bcm43438-bt with shutdown, device-wakeup and host-wakeup GPIOs, max-speed and vddio-supply. Wire uart8 up with its CTS and RTS pins so the module's flow control works. The AP6275S takes its 32.768kHz LPO from Y8 on the board, not from RK809 CLK32KOUT2: R142, which would have connected clkout2 to the module, is DNP. Drop the clkout2 references, correct the comment that claimed otherwise, and drop rockchip,clk-32k-always-on, which made clk-rk808 register clkout2 as CLK_IS_CRITICAL. With no consumer on this board it only kept an unused output powered. This reverses commit 5aa5628 ("arm64: dts: rockchip: keep RK809 clkout2 on for WiFi on Mixtile Edge 2"), which read the LPO source from the device tree rather than from the board. Audio. Drop the audiopwmout_diff, pdm_mic_array, spdif-sound and vad_sound cards and the dummy codecs they used, and disable spdif_8ch, pdm and vad. None of those interfaces are brought out on this board. Add headphone detection on GPIO3_A7 to the remaining card. Regulators. Add m2_lane1_sel on GPIO1_D0, which selects between PCIe and USB 3.0 on the M.2 slot's second lane, and usb_hub_reset on GPIO3_B4. Rename vcc3v3_pcie to vcc3v3_pi6c, after the PI6C clock generator it actually powers, and point the PCIe controller's vpcie3v3-supply at vcc3v3_m2. Rename the vcc1v8_m2_pin pinctrl group to vcc1v8_m2_en, matching the vcc5v0_host_en naming already used here. eMMC. The device reports STROBE_SUPPORT and the data strobe is routed, so add mmc-hs400-1_8v and mmc-hs400-enhanced-strobe. USB. The OTG port is device-only on this board; set dr_mode to peripheral, give it its phy and cap it at high-speed. Also replace the adc-keys node with a recovery gpio-key and drop the generic RK3566/RK3568 IO-domain comment block. Add a mixtile-edge2-m2-usb3 overlay that flips m2_lane1_sel so the M.2 slot's second lane is USB 3.0 instead of PCIe. Signed-off-by: Kevin Zhuang <kevin.zhuang@focalcrest.com>

Add the missing IMX415 digital supplies. The IMX415 driver requests dvdd, dovdd, and avdd, then returns an error when regulator acquisition fails. This node defines only avdd-supply, so probing can fail when the other supplies are unavailable. Add dvdd-supply and dovdd-supply with the regulators connected to the sensor. Use dovdd-supply, not ovdd-supply. This tree has no sony,imx415 binding, and its IMX415 nodes omit link-frequencies; do not add that property based on the IMX412 binding.

Add the required IMX219 supplies to both sensor nodes. The sony,imx219 binding requires VANA-supply, VDIG-supply, and VDDL-supply. Add each property in both overlays with the regulator phandles that provide the Core3588E camera rails.

Declare the HYM8563 clock provider.
The checked-in HYM8563 binding requires #clock-cells = <0>. This node omits that property, so it does not satisfy the binding's clock-provider contract. The repository contains the legacy .txt binding rather than a HYM8563 YAML schema, so this is not an established dtbs_check failure from that YAML.
Proposed fix
hym8563: hym8563@51 {
compatible = "haoyu,hym8563";
+ `#clock-cells` = <0>;
reg = <0x51>;📝 Committable suggestion

There was a problem hiding this comment.
Thanks, Kevin.
Ref the Blade3 rename: that's going to cause breakage for existing users. We should keep the old name existing, with just an #include to the new name, and both in the Makefile. Similar to this - that way we can merge this independent of armbian/build, and old users keep on working.
…tb as an alias Renaming the board file changes the DTB name, which breaks existing installations that boot rk3588-blade3-v101-linux.dtb, and the vendor BOOT_FDT_FILE in armbian/build that points at it. Keep the old name as a wrapper that only includes the new file, and build both DTBs, the way rk3588-nanopc-cm3588-nas.dts does for rk3588-friendlyelec-cm3588-nas.dts. Both DTBs come out byte-identical, so nothing outside this tree has to change. Signed-off-by: Kevin Zhuang <kevin.zhuang@focalcrest.com>

Summary
Fix the device tree descriptions for the Mixtile Blade 3, Core3588E and Edge 2
boards, including their overlays. One commit per board.
The changes were reviewed against the board schematics and the Rockchip vendor
kernel, and the affected boards were subsequently validated on hardware.
Changes
Blade 3
rk3588-blade3-v101-linux.dtstork3588-mixtile-blade3.dtsandupdate the board identity to
Mixtile Blade 3/mixtile,blade3.and the three RK860x from the 4.0V buck. Drop the rails and the four
pcie*_avdd*regulators the board does not have, addvcc3v3_minipcie.Core3588E
suspend.
Edge 2
mixtile,edge2.SDIO pwrseq and serdev bindings.
clkout2. This reverses 5aa5628.
Validation
Blade 3, Core3588E and Edge 2 were each runtime-validated on their own
hardware after these device tree changes.
All three DTBs and the five Mixtile overlays build, and
git diff --checkisclean. The two IMX219 overlays emit the same
reg_formatwarnings as theexisting
radxa-nx5-io-rpi-camera-v2-cam1overlay, which is inherent todescribing an I2C client inside a
/plugin/fragment.The Blade 3 rename changes the DTB name, so it needs the matching
armbian/buildchange, submitted separately as armbian/build#10774. Thatone has to be merged after this.
