Subject: [PATCH v2 0/6] dmaengine: jz4780: Driver updates v2
Date: Mon, 6 Dec 2021 17:42:53 +0000 [thread overview]
Message-ID: <20211206174259.68133-1-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.
Changes since V1 include:
- indentation fixes in patch [1/6],
- a better worded documentation in patch [2/6],
- a new patch [5/6] to convert all uses of uint32_t to u32.
You mentioned the fact that it would be great to have an exemple in the
documentation file that uses #dma-cells = <3>. I will add one in a
future patchset to the SD controller's binding documentation, when its
driver will be updated to support bidirectional DMA channels.
Cheers,
-Paul
