From 86cdd72af936860503f392825410d1b60a3e474e Mon Sep 17 00:00:00 2001 From: Mark Rutland Date: Fri, 9 Sep 2016 14:08:26 +0100 Subject: drivers/perf: arm_pmu: add common attr group fields In preparation for adding common attribute groups, add an array of attribute group pointers to arm_pmu, which will be used if the backend hasn't already set pmu::attr_groups. Subsequent patches will move backends over to using these, before adding common fields.
