Sonoff iHost is gateway device designed to provide a Smart Home Hub,
it is based on Rockchip RV1126. There is also a version with 2GB RAM
based off the RV1109 dual core SoC.
Features:
- Rockchip RV1126
- 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 adds the initial device tree for this device, it is largely
based off the device trees for mainline Edgeble Neu2 and downstream
Rockchip rv1126-evb-v13 configs. It has been adapted with relevant
peripheral and GPIO pins for the iHost.

Changes in v3:
- Move ethernet alias from rv1126.dtsi to board dtsi
Changes in v2:
- Address review comments from Heiko
- Split out rv1109.dtsi to new patch
