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 functionsI 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. - Lars
