Subject: [PATCH v1 01/15] dt-binding: remoteproc: mediatek: Support dual-core SCP
Date: Wed, 1 Jun 2022 19:21:47 +0800 [thread overview]
Message-ID: <20220601112201.15510-2-tinghan.shen@mediatek.com> (raw)
In-Reply-To: <20220601112201.15510-1-tinghan.shen@mediatek.com>
The SCP co-processor is a dual-core RISC-V MCU on MT8195.
Add a new property to identify each core and helps to find drivers
through device tree API to cooperate with each other, e.g. boot flow and
watchdog timeout flow.
Add a new compatile for the driver of SCP 2nd core.
