Subject: [PATCH 0/5] dmaengine: dma-jz4780: Driver updates
Date: Mon, 11 Oct 2021 16:36:47 +0200 [thread overview]
Message-ID: <20211011143652.51976-1-paul@crapouillou.net> (raw)
Hi Vinod,
A small set of updates to the dma-jz4780 driver.
It adds support for the MDMA/BDMA engines in the JZ4760(B) and JZ4770
SoCs, which are just regular cores with less channels.
It also adds support for bidirectional channels, so that devices that
only do half-duplex transfers can request a single DMA channel for both
directions.
Cheers,
-Paul
