Subject: [PATCH v8 2/4] riscv: dts: Add dma-channels property and modify compatible
Date: Mon, 28 Mar 2022 17:52:23 +0800	[thread overview]
Message-ID: <d19daa503fb242eef00d79082931199cb3e48021.1648461096.git.zong.li@sifive.com> (raw)
In-Reply-To: <cover.1648461096.git.zong.li@sifive.com>

Add dma-channels property, then we can determine how many channels there
by device tree, in addition, we add the pdma versioning scheme for
compatible.
