Subject: [PATCH v2 0/3] arm64: dts: amlogic: add support for Orbbec Zora P1
Date: Sun, 26 Jul 2026 22:16:44 +0200	[thread overview]
Message-ID: <20260726201647.264108-1-robazzalberto@gmail.com> (raw)

The Orbbec Zora P1 is a vision development board based on the Amlogic
A311D (Meson G12B) SoC, with 2 or 4 GiB LPDDR4, an Ampak AP6256 combo
module (Broadcom BCM43456 Wi-Fi over SDIO and BCM4345C5 Bluetooth over
UART_A), HDMI output and Gigabit Ethernet.

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.
