feat: Add Seeed Studio reComputer RK3576 SoM dts - #531
Conversation
…-recomputer IO board
WalkthroughAdds a complete RK3576 ReComputer module device tree with board power, multimedia, connectivity, storage, display, USB-C, and pin-control configuration. Adds camera support for IMX708 sensors, autofocus controllers, CSI-2, CIF, ISP, and VPSS paths. Adds a Raspberry Pi 7-inch DSI touchscreen overlay with GT911 touch input and display routing. Registers the new DTB and overlay in the Rockchip build lists. Estimated code review effort: 5 (Critical) | ~120 minutes Merge Risk: 🟠 High · up to This change adds reComputer RK3576 board support, but unresolved device-tree configuration errors can cause camera and GPU features to fail, expose the wrong EEPROM capacity with possible data corruption, and create GPIO or regulator conflicts.

Fix the reset regulator definitions.
cam0_rst and cam1_rst are declared as regulator-fixed, but they carry regulator-name = "cam0_pwr" and "cam1_pwr". Two problems follow:
- The names duplicate the
cam1_pwrregulator declared at Line 21. The regulator core then registers two regulators with the same name, which makesdebugfs,regulator_summary, and log output ambiguous. - Neither node declares a
gpio, so each is a static always-on dummy with no control. Thedw9817VCM drivers consume them asVDD-supply(Lines 98 and 163), so the VCM never actually gets a controlled rail.
Give each node a unique regulator-name, and add the gpio property if the rail is switchable. If these are only placeholders to satisfy VDD-supply, state that in a comment.

pinctrl-names has no matching pinctrl-0.
Both imx708_0 (Line 115) and imx708_1 (Line 181) set pinctrl-names = "default" without a pinctrl-0 property. The pinctrl core builds its mapping from the pinctrl-N properties, so a declared state with no property list produces an error during pinctrl_dt_to_map and can abort sensor probe. Either add the pin group that the sensor needs, or remove pinctrl-names.

Verify the press-threshold-microvolt unit.
press-threshold-microvolt = <1750> is 1.75 mV, while keyup-threshold-microvolt is 1.8 V. With this value the adc-keys driver maps only near-ground readings to the volume-up key, so a floating or noisy channel can report a false key press. If the divider produces about 1.75 V at press, use <1750000>. If it produces a low voltage, use the measured value in microvolts.

Widen the opp-supported-hw bin mask, or confirm that only bin 0 ships.
Every OPP entry sets opp-supported-hw = <0x01 0xffff>. This first cell matches only bin 0. If a module carries silicon that reports a different bin, the OPP core rejects all GPU OPPs again, which is the exact failure this override tries to fix. The GPU then has no usable OPP table.
If several bins can ship on this module, set a mask that covers them, for example <0xff 0xffff>, or add per-bin entries.

Align the PHY node unit addresses with reg.
Both nodes are named phy@1 but set reg = <0x0>. dtc reports a unit_address_vs_reg warning, and readers get the wrong PHY address. The MDIO bus uses reg, so the PHYs are probed at address 0. Rename the nodes to phy@0, or correct reg if the PHYs really sit at address 1.

Resolve the EEPROM size mismatch.
The node is named at24c256@50, but compatible = "atmel,24c32" declares a 4 KiB part. The at24 driver sizes the device from the compatible, so a fitted 24C256 exposes only 4 KiB and address wrap can silently corrupt data past that limit. Set the compatible to the fitted part, and align the node name.

GPIO2_B4 is named as a header pin and also used as the GMAC1 PHY reset.
Line 1215 names GPIO2_B4 "PIN_38", which exposes it as a user header pin. Line 675 assigns the same pin to &gmac1 as snps,reset-gpio. &gmac1 is disabled, so nothing claims the pin today. If someone enables &gmac1, userspace access through "PIN_38" and the PHY reset will fight for the same line. Confirm the schematic, then either drop the name or drop the reset assignment.

Confirm the schematic and remove either the "PIN_38" label or the gmac1 reset
assignment, preserving the intended hardware function when gmac1 is enabled.

The GPIO2 gpio-line-names table names lines that other nodes already claim. The shared root cause is that the header pin map in the board DTS was written without cross-checking the pins consumed by the camera include and the GMAC nodes.
