I didn't realize earlier that this patch is directly modifying
dts/upstream subtree. Modifying the subtree is likely going to cause
conflicts with the next subtree pull. It looks like this board is
targeted for v6.13 release. Let's see if we get lucky with automerge
being successful for this one but let's try to rather use cherry pick
or wait for the board support to land in devicetree-rebasing tree. You
can maintain U-Boot DTS for the time being.
