Subject: [PATCH v6 00/10] arm64: dts: Add Arm Morello support

The Morello architecture is an experimental extension to Armv8.2-A,
which extends the AArch64 state with the principles proposed in
version 7 of the Capability Hardware Enhanced RISC Instructions
(CHERI) ISA [1].

This series adds dts support for the Arm Morello System Development
Platform.

To simplify the testing a linux tree rebased on 6.14-rc4 is accessible
at [2].
