From what you're saying, and judging from the drivers that already
implement it, can't it be moved directly to the framework itself ?
What exactly do you mean by moving it directly to the framework? The
slave_caps API is part of the DMAengine framework.
Not its implementation, which is defined by each and every driver,
while the behaviour of device_slave_caps is rather generic.
Do you mean something like adding a dma_slave_caps struct field to
the DMA channel that gets initialized when the channel is created
and then remove the callback? That makes some sense.
I was rather thinking into something like:
- Splitting device_control into independant functions
I like this part :)
I started working on this a while ago by splitting out the slave_config
functionality into its own callback. Haven't managed to finalize it since it
wasn't really top priority.
