This looks good, however can you split this into 2 different patches and 
add for the first hunk:

Fixes: c8b404fb05dc ("arm64: dts: broadcom: bcm4908: add BCM4906 Netgear 
R8000P DTS files")

and:

Fixes: 2961f69f151c ("arm64: dts: broadcom: add BCM4908 and Asus 
GT-AC5300 early DTS files")

for the second hunk to the commit message?

Thanks!
