Jisheng,

I am trying to follow your request to get rid of 88DExxxx numbering and
replace it where possible with berlin type-of names.

For the above, I have:
"marvell,berlin-bg2" for Marvell Armada 1500 (BG2, 88DE3100)
"marvell,berlin-bg2cd" for Marvell Armada 1500-mini (BG2CD, 88DE3005)

I cannot pin down Armada 1000 in the BG naming scheme. It would be great
if you provide info here on how Marvell would like to see the
compatibles.

Sebastian
