Hi Cyril,
PRU is basically a micro-controller embedded inside of da8xx processors.
To emulate any protocol on it, we need to implement the protocol and
download the firmware into the instruction RAM.
Hence, if the firmware is implemented in such a was that its able to run
different protocols simul

Hi Cyril,
I am referring the SSP driver to implement the PRU MFD driver.
I had a few concerns regarding this.
First of all, does the SSP support multiple execution units, in a sense that
its able to run multiple serial devices at once, like multiple channels.
If so, then its definitely a MFD.

function chosen based on what the board needs.
Codec interface, SPI, GPIO, etc.
If so, then it makes sense for the

Incidentally the ARM PrimeCell PL022 is called SSP,
"Synchronous Serial Port" and is not multifunction at all.
Just to add to the confusion...

On the assumptions you've tested this *AND* will

TI's SSP controller pins can be directly read and written to behave like a
GPIO. This patch adds a GPIO driver that exposes such functionality.
