Subject: [PATCH 2/2] dma: jz4780: Add support for the JZ4760(B)
Date: Wed, 20 Jan 2021 10:53:22 +0000 [thread overview]
Message-ID: <20210120105322.16116-2-paul@crapouillou.net> (raw)
In-Reply-To: <20210120105322.16116-1-paul@crapouillou.net>
Add support for the JZ4760 and JZ4760B SoCs.
Both SoCs have only 5 DMA channels per chip. The JZ4760B introduced the
DCKES/DCKEC registers.
