[PATCH v1] dt-bindings: perf: riscv,pmu: fix property dependencies

From: Conor Dooley
Date: Tue Apr 04 2023 - 14:04:33 EST


From: Conor Dooley <conor.dooley@xxxxxxxxxxxxx>

Seemingly I mis-implemented the dependencies here. The OpenSBI docs only
point out that the "riscv,event-to-mhpmcounters property is mandatory if
riscv,event-to-mhpmevent is present". It never claims that
riscv,event-to-mhpmcounters requires riscv,event-to-mhpmevent.

Drop the dependency of riscv,event-to-mhpmcounters on
riscv,event-to-mhpmevent.

Fixes: 7e38085d9c59 ("dt-bindings: riscv: add SBI PMU event mappings")

Atish, I'm not 100% on this one but I noticed it while doing dt-validate
on a dump of the qemu virt machine which doesn't use the
event-to-mhpmevent property.
