From 3fea68f6c39f83bfcd8de2c52351e82a82ed05aa Mon Sep 17 00:00:00 2001

Subject: [PATCH 643/773] 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
