Subject: [PATCH v2 2/3] LoongArch: dts: Add new supported device nodes to Loongson-2K0500
Date: Thu, 9 May 2024 14:18:05 +0800 [thread overview]
Message-ID: <44c3bcd02598894f838e7c6dd205a139fd388ff8.1715222938.git.zhoubinbin@loongson.cn> (raw)
In-Reply-To: <cover.1715222938.git.zhoubinbin@loongson.cn>
By now, more Loongson-2K0500 related drivers are supported, such as
clock controller, thermal controller, and dma controller.
Now we add these device nodes to the Loongson-2K0500 dts file.
