+Subject: [PATCH] arm: dts: Change downstream vchiq compatible string
+
+The new cache line size mechanism requires a different vchiq compatible
+string on BCM2836 and BCM2837, but the downstream dts files didn't
+inherit the upstream changes.
+
+See: https://github.com/raspberrypi/linux/issues/2643
