Subject: [PATCH v3 0/8] Add support for Sonoff iHost RV1126 Smart Home Gateway
Date: Sun,  3 Dec 2023 23:39:56 +1100	[thread overview]
Message-ID: <20231203124004.2676174-1-tim@feathertop.org> (raw)

Sonoff iHost is gateway device designed to provide a Smart Home Hub,
most notably it includes builtin radios for Wifi, BT and Zigbee, which
make it suitable SBC for use with many of the open home automation
platforms. It is availabe in two versions, first is based on
Rockchip RV1126 and 4GB DDR4 RAM. There is a second version based off
the RV1109 dual core SoC and 2GB RAM.

Features:
- Rockchip RV1126 (or RV1109)
- 4GB DDR4
- 8GB eMMC
- microSD slot
- RMII Ethernet PHY
- 1x USB 2.0 Host
- 1x USB 2.0 OTG
- Realtek RTL8723DS WiFi/BT
- EFR32MG21 Silabs Zigbee radio
- Speaker/Microphone

This patch series adds the various device tree nodes required to
support this device. It also adds the initial dts for this device,
This work was largely based off the device trees for mainline
Edgeble Neu2 and downstream Rockchip rv1126-evb-v13 configs.
It has been adapted with relevant peripherals and GPIO pins for the
iHost.

Implemented in this series are most of the core periperhals including
Ethernet, Wifi, BT, Zigbee and RTC. Sound and USB will be added in a
later series.

Changes in v3:
- i2c: add code comment and clarify commit message further
- i2c: Collect ack by Heiko
- Move ethernet alias from rv1126.dtsi to board dtsi

Changes in v2:
- i2c: clarify commit message
- Address review comments from Heiko
- Split out rv1109.dtsi to new patch
- Collect Robh Ack for dt-bindings patch
