[v2] Add parents to struct pmu -> dev

[PATCH v2 25/30] ARM: imx: Assign parents for mmdc event_source devices

Posted by Jonathan Cameron 1 year, 10 months ago

Currently the PMU device appears directly under /sys/devices/
Only root busses should appear there, so instead assign the pmu->dev
parent to be the platform device.
