Subject: [PATCH v2 05/25] dt-bindings: timer: arm,arch_timer: Add interrupt-names support
Date:   Mon, 15 Feb 2021 21:16:53 +0900

Not all platforms provide the same set of timers/interrupts, and Linux
only needs one (plus kvm/guest ones); some platforms are working around
this by using dummy fake interrupts. Implementing interrupt-names allows
the devicetree to specify an arbitrary set of available interrupts, so
the timer code can pick the right one.

This also adds the hyp-virt timer/interrupt, which was previously not
expressed in the fixed 4-interrupt form.
