WalkthroughAdds RK3576 reComputer SoM device-tree support with WiFi, Bluetooth, multimedia, networking, USB, EEPROM, RTC, and storage configurations. Adds eMMC and SPI-NOR variants. Adds the Industrial carrier board description with audio, LEDs, buzzer, watchdog, USB-C, DisplayPort, Ethernet, CAN, PCIe, LoRa, GPIO, and build-target support. Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🟡 Moderate · up to The device-tree definitions currently prevent the SX1261 LoRa userspace interface from appearing, and the boot-mode ADC key may fail binding validation. These are localized but concrete current-head issues, so merge should wait for fixes or explicit owner acceptance. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

In `@arch/arm64/boot/dts/rockchip/rk3576-recomputer-industrial.dts`:
- Line 37: Update the compatible value in the device-tree definition to use the
space-free hyphenated model identifier, preserving the existing vendor prefix
and secondary Rockchip compatible entry.
In `@drivers/net/phy/maxio.c`:
- Around line 54-71: Update the LED configuration function around the error
label and final MAE0621A_PAGE_SELECT call so page zero is attempted on every
exit, including failures in the LEDCR or MAE0621A_LED_REG11 writes. Preserve an
earlier write error, but if no earlier error exists, return the page-reset
phy_write() error instead of success.
- Around line 112-116: Update the MODULE_DEVICE_TABLE declaration for maxio_tbl
to use the mdio module-table type instead of mdio_bus_id, preserving the
existing struct mdio_device_id entries so modular PHY detection emits the
correct modalias.
- Around line 96-102: Update the registration flow around
phy_register_fixup_for_uid and phy_drivers_register so a successfully registered
maxio_led_init fixup is removed if driver registration fails. Also update
maxio_exit to unregister the UID fixup before unloading the module, ensuring
cleanup occurs only when fixup registration succeeded.

changed the title
FT24C32 nWP is GPIO0_D1 (high = write-protect, low = writable). The at24 driver in this kernel does not toggle a wp-gpios line, so hog GPIO0_D1 low to allow page writes (read/write/restore test). Syncs rk3576-recomputer-industrial.dts with build-side patch 002-recomputer-rk3576-industrial-dts.patch (commit c9dccc6fd). Signed-off-by: Ming Zhangqun <north_sea@qq.com>
