Subject: [PATCH v3 5/5] arm64: dts: add support for A5 based Amlogic AV400
Date: Mon, 01 Apr 2024 18:10:53 +0800 [thread overview]
Message-ID: <20240401-basic_dt-v3-5-cb29ae1c16da@amlogic.com> (raw)
In-Reply-To: <20240401-basic_dt-v3-0-cb29ae1c16da@amlogic.com>
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.
