i'm working on a project which depends on 5 Wire SPI communication. It
is probably identical to spi-davinci.c with SPI_READY signal. Only
difference is that SPI_READY is not supported by hardware, in this case
GPIO input is used.

Sounds interesting!

Currently this project implements SPI_READY and CS on top of spidev
driver. What makes it really ugly, slow and complicated.

Can you please point me to some SPI slave hardware that supports this?

It is automotive filed. Used for inter chip communication.
There are many products with it. Currently i can't say more :(

Thanks a lot!
