This patch series aims to add serdev_device_id to the serdev drivers
so as to support platform instantiation of a serdev device.The first
two patches adding the serdev_device_id has already been once submitted
by Ricardo Ribalda Delgado(in CC) here:
https://lore.kernel.org/lkml/20180611115240.32606-1-ricardo.ribalda@gmail.com/

The problem currently trying to solved is bit different from dynamically
loading/removing serdev devices as addressed in the original patch series,
the aim now is to attach a serdev driver once to a device that is not a part of
the device tree or the ACPI table, Eg. a device on a greybus created gbphy uart.

The patches were tested with a set of uBlox GNSS Receiver Clicks on a PocketBeagle.
The serdev_device_id table is exported only for a single driver(drivers/gnss/ubx.c)
for reference.

Ricardo Ribalda (2):
  serdev: Add serdev_device_id
  file2alias: Support for serdev devices

Vaishnav M A (3):
  serdev: add of_ helper to get serdev controller
  gnss: ubx add MODULE_DEVICE_TABLE(serdev)
  gnss: change of_property_read to device_property_read
