[RFC 0/1] i2c/aspeed: Add slave device handling in new register mode

[Peter Delevoryas]

The AST2600/AST1030 new register mode patches[1] and the I2C slave device
patches[2] will be really useful, but we still need DMA slave device
handling in the new register mode too for the use-cases I'm thinking of
(OpenBIC Zephyr kernel using Aspeed SDK drivers[3]).

My test images are on Github[4]. They can be used with the ast1030-evb, or
the oby35-cl and oby35-bb machines in the fb qemu branch[5].

I'm submitting this as an RFC cause I just want to see how other people
expect these changes to be made based on the previously submitted "new
register mode" and "old register mode slave device" patches.

Thanks,
Peter
