     I'd put the above into a separate patch...

Why should addition of clock data not be in the same patch
as the one which adds platform resources etc? It is not a big
deal to change, but I would like to know why you request this.

    I didn't request anything, I just said what I'd have done. :-)

Okay. I guess I will keep it as is.

I think modifying the DA8xx-common and DA850-specific files should better be done separately. Although in this case we're adding DA850 only device, so perhaps the added code in devices-da8xx.c should be enclosed into #ifdef?

Good point. Will add the #ifdef.

   Or perhaps the device should just be placed in da850.c instead?

WBR, Sergei
