Nikolaos Pasaloukos April 6, 2023, 10:22 a.m. UTC
Adds support for the Blaize CB2 development board based on
BLZP1600 SoC. This consists of a Carrier-Board and a SoM.

The blaize-blzp1600.dtsi is the common part for the SoC,
blaize-blzp1600-som.dtsi is the common part for the SoM and
blaize-blzp1600-som-cb2.dts is the board specific file.

DTS cannot go with defconfig or other pieces. DTS is separate, always.

SoM or board? I commented about this in your bindings patch, so now it
visible more that it is wrong.

This is property of the board usualy, not SoC. Although I am not sure
what's this file about - there is already SoM DTSI.

Nope, that's not for DTS in mainline.

New platforms should be free of warnings from 'make dtbs_check'. Please 
run and fix if you have not, and confirm that in the commit message.
