That has been done mostly through two steps: by moving out the sub-commands of the device_control callback, so that the dmaengine core can then infer from that wether a sub-command is implemented, and then by moving the slave properties, such as the supported buswidth, to the structure dma_device itself. Comments are as usual appreciated! Thanks, Maxime Changes from v4: - Rebased on top of current dma/next - Converted AT91 XDMAC driver to the new API - Updated the documentation to reflect our changes Changes from v3: - Removed the generic_slave_caps flag - Merged the patch introducing a generic slave caps functions with the one introducing the dma_device capabilities Changes from v2: - Reworked dma_chan_get/dma_chan_put in order to optionally use device_alloc_chan_resources/device_free_chan_resources - Modified a few client drivers that were still calling device_control directly to use the dmaengine API instead - Totally remove device_control and device_slave_config - Move device_control BUG_ON removal earlier in the patch set to avoid breaking the bisectability - Converted rapidio tsi721 driver too. - Minor cosmetics changes and fixes suggested by Laurent Pinchart and Andy Shevchenko - Fixed a few build warnings - Collected the various Acked-by - Rebased on top of 3.18-rc1 Changes from v1: - Add a flag to trigger the generic slave caps mechanism - Add a warning whenever this flag is not set, or when a device_control callback is still defined - Migrate all existing users to use the new callbacks, and
