The device on this spi bus is a FPGA with 4 functions and looking at other projects I've changed it to a resource-controller node name. On cs0 there is a sub-device reset-controller added in the upcoming patchset to enable hardware reset of the eMMC device.

Yes, because adding a compatible was nacked. We have a driver added (two actually, mfd and reset driver) for the next patch update.

Removed where not needed

Yes, moved reg to be right after compatible

Changed to syscon

Yes, removed "simple-mfd"
