Subject: [PATCH 26/32] arc: Assign parents for event_source devices
Date:   Tue, 4 Apr 2023 14:42:19 +0100
Message-ID: <20230404134225.13408-27-Jonathan.Cameron@huawei.com>
In-Reply-To: <20230404134225.13408-1-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.
