Subject: [RESEND PATCH 06/19] arm64: allwinner: a100: Add device node for DMA controller
Date: Tue, 10 Nov 2020 14:29:32 +0800 [thread overview]
Message-ID: <1b15266045edbcfff2fc3791c88a5390d7bb3185.1604988979.git.frank@allwinnertech.com> (raw)
In-Reply-To: <cover.1604988979.git.frank@allwinnertech.com>
From: Yangtao Li <frank@allwinnertech.com>
The A100 SoC has a DMA controller that supports 8 DMA channels
to and from various peripherals.
Add a device node for it.
