+  The EcoNet High Precision Timer (HPT) is a timer peripheral found in various
+  EcoNet SoCs, including the EN751221 and EN751627 families. It provides per-VPE
+  count/compare registers and a per-CPU control register, with a single interrupt
+  line using a percpu-devid interrupt mechanism.

This goes under allOf:, to save re-indent later, and then after

because it is redundant. Bus/parent addressing already defines this as
base address, cannot be anything else.
