Subject: [PATCH v5 0/3] add support for Mediatek High-Speed DMA controller on MT7622 and MT7623 SoC
Date: Sun, 18 Feb 2018 03:08:28 +0800 [thread overview]
Message-ID: <cover.1518857746.git.sean.wang@mediatek.com> (raw)
From: Sean Wang <sean.wang@mediatek.com>
Changes since v4:
- rebase to 4.16-rc1
- fold back patch 4 and 5 in v4 into the original commit
- add the missing header included
- fix typo and add more explanation in existing comments
- fix the comments with kernel-doc style which uses /** as the begin
- begin the multi-line comments with /*
Changes since v3:
- enhance dt-binding documents based on Rob's comments
- make consistent among all comments
- perfer ordering declarations longest to shortest
- fix warning reported from kbuild test robot
- add patch 4 and 5 to keep Fengguang and Julia's effort
Changes since v2:
- remove extra tasklets and refactor driver for letting descriptors being processed ASAP.
- add more comments stating the relevant logic
- remove unused macro and variables
- change to use the disclaimer with SPDX identifier
- add mt7622 support
- refine hardware initialization sequence
- add tx_status support for DMA_RESIDUE_GRANULARITY_SEGMENT
- refine remove handler with killing vc's tasklet
Changes since v1:
- fix typo in the commit message.
- delete status shown in the dt-binding example.
This patchset introduces support for MediaTek High-Speed DMA controller
(MTK-HSDMA) Currently, the driver is already tested successfully with
dmatest module on MT7622 and MT7623 SoC.
MTK-HSDMA on MT7622/23 SoC has a single ring which is dedicated for
doing memory-to-memory transfer through ring-based descriptor management.
Even though there is only a single ring available inside HSDMA, the
driver is being extended to the support for multiple virtual channels
processing simultaneously by means of DMA_VIRTUAL_CHANNELS.
