[PATCH v2 3/3] arm64: dts: meson-axg: add support for JetHub D1

From: Vyacheslav Bocharov
Date: Fri Sep 03 2021 - 02:01:24 EST

JetHome Jethub D1 (http://jethome.ru/jethub-d1) is a home automation controller with the following features:
- DIN Rail Mounting
- Amlogic A113X (ARM Cortex-A53) quad-core up to 1.5GHz
- no video out
- 512Mb/1GB LPDDR4
- 8/16GB eMMC flash
- 1 x USB 2.0
- 1 x 10/100Mbps ethernet
- WiFi / Bluetooth AMPAK AP6255 (Broadcom BCM43455) IEEE 802.11a/b/g/n/ac, Bluetooth 4.2.
- TI CC2538 + CC2592 Zigbee Wireless Module with up to 20dBm output power and Zigbee 3.0 support.
- 2 x gpio LEDS
- GPIO user Button
- 1 x 1-Wire
- 2 x RS-485
- 4 x dry contact digital GPIO inputs
- 3 x relay GPIO outputs
- DC source with a voltage of 9 to 56 V / Passive POE
