[PATCH 0/9] dmaengine: Implement generic slave capabilities retrieval

[Maxime Ripard]

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
