Subject: [PATCH v6 0/2] Add support for Loongson1 DMA
Date: Sat, 16 Mar 2024 19:33:52 +0800 [thread overview]
Message-ID: <20240316-loongson1-dma-v6-0-90de2c3cc928@gmail.com> (raw)
Add the driver and dt-binding document for Loongson1 DMA.
Changelog
V5 -> 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
V4 -> 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
V3 -> 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.
V2 -> V3:
Rename ls1x_dma_filter_fn to ls1x_dma_filter.
V1 -> V2:
Change the config from 'DMA_LOONGSON1' to 'LOONGSON1_DMA',
and rearrange it in alphabetical order in Kconfig and Makefile.
Fix comment style.
