Subject: [PATCH v2 1/2] uio_pdrv_genirq: convert to use device_property APIs
Date: Tue,  9 Apr 2024 11:40:48 +1200

Convert the uio_pdrv_genirq driver to use the device_property_* APIs
instead of the of_property_* ones. This allows UIO interrupts to be
defined via an ACPI overlay using the Device Tree namespace linkage.
