Subject: [PATCH v4 00/15] dmaengine: dw-axi-dmac: support Intel KeemBay AxiDMA
Date: Tue, 17 Nov 2020 10:22:00 +0800 [thread overview]
Message-ID: <20201117022215.2461-1-jee.heng.sia@intel.com> (raw)
The below patch series are to support AxiDMA running on Intel KeemBay SoC.
The base driver is dw-axi-dmac. This driver only support DMA memory copy
transfers. Code refactoring is needed so that additional features can be
supported.
The features added in this patch series are:
- Replacing Linked List with virtual descriptor management.
- Remove unrelated hw desc stuff from dma memory pool.
- Manage dma memory pool alloc/destroy based on channel activity.
- Support dmaengine device_sync() callback.
- Support dmaengine device_config().
- Support dmaengine device_prep_slave_sg().
- Support dmaengine device_prep_dma_cyclic().
- Support of_dma_controller_register().
- Support burst residue granularity.
- Support Intel KeemBay AxiDMA registers.
- Support Intel KeemBay AxiDMA device handshake.
- Support Intel KeemBay AxiDMA BYTE and HALFWORD device operation.
- Add constraint to Max segment size.
This patch series are tested on Intel KeemBay platform.
v4:
- Fixed bot found errors running make_dt_binding_check.
- Added minItems: 1 to the YAML schemas DT binding.
- Updated "reg" field to the YAML schemas DT binding.
v3:
- Added additionalProperties: false to the YAML schemas DT binding.
- Reordered patch sequence for patch 10th, 11th and 12th so that
DT binding come first, follow by adding Intel KeemBay SoC registers
and update .compatible field.
- Checked txstate NULL condition.
- Created helper function dw_axi_dma_set_hw_desc() to handle common code.
v2:
- Rebased to v5.10-rc1 kernel.
- Added support for dmaengine device_config().
- Added support for dmaengine device_prep_slave_sg().
- Added support for dmaengine device_prep_dma_cyclic().
- Added support for of_dma_controller_register().
- Added support for burst residue granularity.
- Added support for Intel KeemBay AxiDMA registers.
- Added support for Intel KeemBay AxiDMA device handshake.
- Added support for Intel KeemBay AxiDMA BYTE and HALFWORD device operation.
- Added constraint to Max segment size.
v1:
- Initial version. Patch on top of dw-axi-dma driver. This version improve
the descriptor management by replacing Linked List Item (LLI) with
virtual descriptor management, only allocate hardware LLI memories from
DMA memory pool, manage DMA memory pool alloc/destroy based on channel
activity and to support device_sync callback.
