[PATCH v2 5/5] arm64: dts: add support for A5 based Amlogic AV400
Posted by Xianwei Zhao via B4 Relay 1 year, 10 months ago 
From: Xianwei Zhao <xianwei.zhao@amlogic.com>

Amlogic A5 is an application processor designed for smart audio
and IoT applications.

Add basic support for the A5 based Amlogic AV400 board, which describes
the following components: CPU, GIC, IRQ, Timer and UART.
These are capable of booting up into the serial console.
