Re: [PATCH v9 6/6] drivers: remoteproc: Add Xilinx r5 remoteproc driver

[Tanmay Shah]

Thanks Mathieu.

Also, I see that last few revisions I have changed driver a lot based on 
comments, but documentation in driver is not in sync.

I know we agreed initially, that I will address changes _only_ commented 
in previous revision. However, in next revision I would like

to fix documentation all over the driver along with your comments. I 
hope it's fine and I wanted to give you heads up so we stay on same page.

Thanks,

Tanmay
