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
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 the
generic slave capabilities
