[PATCH v2 0/2] new Atmel DMA controller

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

This set of patches introduces support for the new Atmel DMA controller know as
XDMAC and available on SAMA5D4.

Changes from:
- v1
  - add power management stuff
  - check maxburst value
  - revert subsys_initcall remove, EPROBE_DEFER not yet available on the kernel
  version I use to do the tests, moreover other devices are not ready to use it

- RFC:
  - DMA_SUCCESS replaced by DMA_COMPLETE
  - fix memcpy issue caused by a mistake in interfaces used
  - add filter function
  - remove some parameters from device tree since we can get them through the
  dma slave configuration
  - use readl/writel relaxed
  - remove subsys_initcall
  - synchronize irq before killing tasklets
  - use BIT macro
  - misc cleanup
