Subject: [PATCH v2 0/7] introduce fwnode in the I2C subsystem
Date: Wed, 23 Mar 2022 10:18:03 +0100 [thread overview]
Message-ID: <20220323091810.329217-1-clement.leger@bootlin.com> (raw)
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.
I2C mux support has also been modified to support fwnode based
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.

---------------
Changes in V2:
- Remove sfp modifications
- Add property_read_string_index fwnode_operation callback
- Implement .property_read_string_index for of and swnode
- Renamed np variable to fwnode
Clément Léger (7):
device property: add fwnode_property_read_string_index()
of: property: implement .property_read_string_index callback
software node: implement .property_read_string_index callback
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
