[PATCH v2] iio: proximity: as3935 change of_property_read to device_property_read

From: Vaishnav M A
Date: Sat Oct 17 2020 - 23:17:46 EST


replace the of_property_read_u32 for reading
the ams,tuning-capacitor-pf, ams,nflwdth properties with
device_property_read_u32, allows the driver to get the properties
information using the more generic device_property_* helpers and opens
the possibility of passing the properties during platform instantiation
of the device by a suitably populated struct property_entry
