From eb4f5213251833567570df1a09803f895653274d Mon Sep 17 00:00:00 2001 From: Shaokun Zhang Date: Fri, 4 Jan 2019 14:21:34 +0800 Subject: drivers/perf: hisi: Fixup one DDRC PMU register offset For DDRC PMU, each PMU counter is fixed-purpose. There is a mismatch between perf list and driver definition on rw_chg event. # perf list | grep chg hisi_sccl1_ddrc0/rnk_chg/ [Kernel PMU event] hisi_sccl1_ddrc0/rw_chg/ [Kernel PMU event] But the register offset of rw_chg event is not defined in the driver, meanwhile bnk_chg register offset is mis-defined, let's fixup it.
