[PATCH 0/3] arm64: dts: ti: k3-am62a/p: Add r5fss nodes

[Markus Schneider-Pargmann]

Hi,

am62p-wakeup already has the r5fss node defined, but it is currently
missing from the am62a-wakeup domain in the devicetree. This is added as
part of the series.

For am62a and am62p starter kit boards the r5fss memory region is added
and referenced for the r5fss core 0 node.

Best
Markus
