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.
