Subject: [PATCH v3 2/7] ARM: dts: sun8i: v3s: add DMA properties to peripherals supporting DMA
Date: Fri, 14 May 2021 15:44:00 +0200	[thread overview]
Message-ID: <20210514134405.2097464-3-t.schramm@manjaro.org> (raw)
In-Reply-To: <20210514134405.2097464-1-t.schramm@manjaro.org>

This commit adds DMA properties to all peripherals supporting DMA on the
Allwinner V3s, enabling accelerated data transfer to them.
