Subject: [PATCH 29/32] fpga: dfl: Assign parent for event_source device
Date:   Tue, 4 Apr 2023 14:42:22 +0100
Message-ID: <20230404134225.13408-30-Jonathan.Cameron@huawei.com>

Precedence: bulk

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.
