12description:
13 The EcoNet High Precision Timer (HPT) is a timer peripheral found in various
14 EcoNet SoCs, including the EN751221 and EN751627 families. It provides per-VPE
15 count/compare registers and a per-CPU control register, with a single interrupt
16 line using a percpu-devid interrupt mechanism.
