Hi,
As we discussed a couple of weeks ago, this is a first attempt at creating a generic behaviour for slave capabilities retrieval so that generic layers using dmaengine can actually rely on that.
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
Maxime Ripard (9): dmaengine: Make the destination abbreviation coherent dmaengine: Make channel allocation callbacks optional dmaengine: Introduce a device_config callback dmaengine: split out pause/resume operations from device_control dmaengine: Add device_terminate_all callback dmaengine: Create a generic dma_slave_caps callback dmaengine: Move slave caps to dma_device dmaengine: Mark device_control as deprecated dmaengine: sun6i: Convert to generic slave_caps
