According to its specifications and original device tree, the board is a revised version of the ODROID-N2 with Wi-Fi, Bluetooth and an Amlogic A311D instead of the original S922X. The device tree therefore builds on meson-g12b-a311d.dtsi and meson-g12b-odroid-n2.dtsi, mirroring meson-g12b-odroid-n2-plus.dts. It extends those descriptions with the board-specific AP6256 wiring. The status LED is green instead of the original ODROID-N2 blue and has inverted polarity. This series consists of: Patch 1: add the "orbbec" vendor prefix. Patch 2: document the "orbbec,zora-p1" board compatible. Patch 3: add the meson-g12b-zora-p1.dts board file and Makefile entry. The DTB was built, validated against the amlogic.yaml binding using DT_SCHEMA_FILES, and boot-tested twice on the board. The AP6256 Wi-Fi interface enumerates and operates with the GPIOX_16 reset and PWM clock description present. Removing the wifi32k and pwm_ef descriptions causes the SDIO Wi-Fi device to stop working on this board. --- Changes in v2: - Investigated the apparent GPIOX_16 overlap between the SDIO power sequence reset and the 32.768 kHz PWM clock. Retained the description after two successful hardware tests; removing the clock description prevents the AP6256 Wi-Fi device from working. - Sort the new DTB entry alphabetically in the Amlogic Makefile. - Sort the "orbbec" entry alphabetically in vendor-prefixes.yaml. --- Changes in v3: - Polished meson-g12b-zora-p1.dts. - Use proper comment with /* and */. - Use the new bindings with function and color properties instead of label in leds node. - Include dt-bindings/leds/common.h. --- Changes in v4: - Dropped unnecessary sentences from patch 1 and 2. - Renamed "wifi32k" node to "clock-32768" as updated guidelines suggest.
