As reported already in this thread, this adds a crap load of warnings as 
it makes ports or port required. Sigh. Can QCom folks pay more attention 
to this please. Every cycle the number goes up though that's often 
temporary because there's no coordination of taking .dts files after 
bindings. But generally, progress on QCom warnings has stalled.

Here's the top (bottom?) platforms in arm64. The first number is 
total warnings. The 2nd number is unique warnings (to remove inflated 
numbers due to lots of boards per SoC).

mediatek:785:166
hisilicon:133:112
qcom:362:104
broadcom:286:104
marvell:558:80
apm:78:58
rockchip:128:57
nvidia:199:53
sprd:30:29
xilinx:94:22

Congrats on 3rd place. There's a bunch of pending Mediatek fixes, so I 
expect you all will move up to 2nd soon. 

All this data is updated daily. There's some scripts to get and process 
the logs here[1].
