From a6cf39fbe133857a7f26f0cab8198869caf44dee Mon Sep 17 00:00:00 2001 From: Hector Martin Date: Sun, 14 Feb 2021 16:07:27 +0900 Subject: dt-bindings: timer: arm,arch_timer: Add interrupt-names support 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.
