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.
The PRUSS was named as DMAX on da830 platform.
This patch resolves the naming conflict by replacing the macro
DA8XX_LPSC0_DMAX with DA8XX_LPSC0_PRUSS.
