This patch set add hardware sampling support for csky-pmu, and also add some properties to pmu node definition. perf can record on hardware event with this patch applied.
Changes since v2: - update dt-binding(csky pmu use rising edge interrupt) - use cpuhp_setup_state to enable irq(fix irq enable on smp)
Changes since v1: - do not update hpcr when event type is invalid(fix option --all-kernel/--all-user)
Guo Ren (1): csky: Fixup some error count in 810 & 860.
Mao Han (5): csky: Init pmu as a device csky: Add reg-io-width property for csky pmu csky: Add pmu interrupt support dt-bindings: csky: Add csky PMU bindings csky: Fix perf record in kernel/user space
