Hi all,

After merging the arm-soc tree, today's linux-next build (arm
multi_v7_defconfig) produced this warning:

arch/arm/boot/dts/bcm47094-asus-rt-ac88u.dts:109.4-14: Warning (reg_format): /switch/ports:reg: property has invalid length (4 bytes) (#address-cells == 2, #size-cells == 1)

Maybe introduced by commit

  3d2d52a0d183 ("ARM: dts: BCM5301X: define RTL8365MB switch on Asus RT-AC88U")

Confirmed, and now reverted as I'm already tagging the final pull requests.

Arınç, Florian: Feel free to resubmit a fixed version for the "late"
branch that Olof
may still pick up when I'm out of office, in case this is an important
change. Otherwise
I guess we can leave it for 5.18

        Arnd
