+Subject: [PATCH] ARM: dts: bcm271x: Use a53 pmu, drop RPI364
+
+The upstream bcm2837.dtsi uses cortex-a53-pmu, so we can do the same
+but with a fallback to the cortex-a7-pmu which is supported by the
+32-bit kernel.
+
+Now that we're using the natural fallback mechanism of compatible
+strings, the RPI364 macro no longer serves any purpose - remove it.
