Subject: [PATCH 0/6] introduce fwnode in the I2C subsystem

In order to allow the I2C subsystem to be usable with fwnode, add
some functions to retrieve an i2c_adapter from a fwnode and use
these functions in both i2c mux and sfp. ACPI and device-tree are
handled to allow these modifications to work with both descriptions.

This series is a subset of the one that was first submitted as a larger
series to add swnode support [1]. In this one, it will be focused on
fwnode support only since it seems to have reach a consensus that
adding fwnode to subsystems makes sense.

Clément Léger (6):
  property: add fwnode_property_read_string_index()
  i2c: fwnode: add fwnode_find_i2c_adapter_by_node()
  i2c: of: use fwnode_get_i2c_adapter_by_node()
  i2c: mux: pinctrl: remove CONFIG_OF dependency and use fwnode API
  i2c: mux: add support for fwnode
  net: sfp: add support for fwnode
