Subject: [PATCH v7 0/2] Add support for Loongson1 APB DMA
Date: Fri, 29 Mar 2024 19:26:56 +0800 [thread overview]
Message-ID: <20240329-loongson1-dma-v7-0-37db58608de5@gmail.com> (raw)
Add the driver and dt-binding document for Loongson1 APB DMA.
Changes in v7:
- Change the comptible to 'loongson,ls1*-apbdma' (suggested by Huacai Chen)
- Update the title and description part accordingly
- Rename the file to loongson,ls1b-apbdma.yaml
- Add a compatible string for LS1A
- Delete minItems of 'interrupts'
- Change patterns of 'interrupt-names' to const
- Rename the file to loongson1-apb-dma.c to keep the consistency
- Update Kconfig and Makefile accordingly
- Link to v6: https://lore.kernel.org/r/20240316-loongson1-dma-v6-0-90de2c3cc928@gmail.com
Changes in v6:
- Change the compatible to the fallback
- Implement .device_prep_dma_cyclic for Loongson1 sound driver,
- as well as .device_pause and .device_resume.
- Set the limitation LS1X_DMA_MAX_DESC and put all descriptors
- into one page to save memory
- Move dma_pool_zalloc() into ls1x_dma_alloc_desc()
- Drop dma_slave_config structure
- Use .remove_new instead of .remove
- Use KBUILD_MODNAME for the driver name
- Improve the debug information
- Some minor fixes
-
Changes in v5:
- Add the dt-binding document
- Add DT support
- Use DT information instead of platform data
- Use chan_id of struct dma_chan instead of own id
- Use of_dma_xlate_by_chan_id() instead of ls1x_dma_filter()
- Update the author information to my official name
-
Changes in v4:
- Use dma_slave_map to find the proper channel.
- Explicitly call devm_request_irq() and tasklet_kill().
- Fix namespace issue.
- Some minor fixes and cleanups.
-
Changes in v3:
- Rename ls1x_dma_filter_fn to ls1x_dma_filter.
-
Changes in v2:
- Change the config from 'DMA_LOONGSON1' to 'LOONGSON1_DMA',
- and rearrange it in alphabetical order in Kconfig and Makefile.
- Fix comment style.
