Subject: [PATCH 9/9] arm64: dts: ti: k3-am69-sk: Add overlay for IMX219
RPi v2 Camera (IMX219) is an 8MP camera that can be used with SK-AM69
through the 22-pin CSI-RX connector.
Same overlay can be used across AM68 SK, TDA4VM SK boards that have a
15/22-pin FFC connector. Also enable build testing and symbols for
all the three platforms.
