Hi Jassi,

quoted

However, if SCU (in its current form) must be supported. We may need
to add the third cell (irq enable or not) or some better way, right
now.

Looking at imx_mu_scu_send_data(), which simply polls on the tx, I think we
don't even need third cell for scu client. A simple 2-cell, 8 uni-dir channel
setup should work.

How would you suggest to use for SCU in 2 -cells?

If I see the scu client driver, I could confirm how it would work.

I've already given a general overview from here:
https://www.spinics.net/lists/arm-kernel/msg669202.html

Do you need me to send the full scu client driver patch for the reference?
If yes, please feel free to let me know.

So, lets please do the 8 uni-directional, 2 cells implementation.

Regards.
