NetBSD pinebook 9.99.93 NetBSD 9.99.93 (GENERIC64) #4: Thu Jan 20 22:39:15 EST 2022  ml@paddy:/disk/build/obj_earm64/sys/arch/evbarm/compile/GENERIC64 evbarm

>Description:
after updating kernel and dtbs sunxidrm errors out and leaves a blank screen on pinebook, the machine boots otherwise and can be talked to via ssh. New kernel and older dtbs work.
Relevant dmesg snippets:

Jun Ebihara seems to have encountered the same problem ( see port-arm@, 'pinebook status update (20220119)' ):
Problems:
- pinebook: 
  need backout dts.tgz to 202111060010Z.due to display issue.

>How-To-Repeat:
boot -current with recent dtbs on a pinebook
>Fix:
put old dtbs back as a workaround

committed a fix a while ago
Module Name:	src
Committed By:	macallan
Date:		Fri Jan 21 21:00:26 UTC 2022

Modified Files:
	src/sys/dev/fdt: fdt_port.c

Log Message:
when enumerating ports and endpoints treat missing 'reg' properties as zero
ok jmcneill:
Looking at Linux. If port or endpoint are missing a 'reg' property it defaults to 0.
Please make our code do the same.

see https://github.com/devicetree-org/dt-schema/blob/main/dtschema/schemas/graph.yaml

with this my pinebook has a usable console again
