Subject: [PATCH 2/2] arm64: dts: NS2: add support for XMC form factor
The BCM958712DxXMC board is a smaller form factor typically used as
controller boards for switches. This smaller board has less devices
pinned out, so only a few need be populated in the device tree.
Signed-off-by: Jon Mason <jon.mason@...adcom.com>
