[PATCH v2 0/6] i2c: core: Move client towards fwnode

The struct i2c_board_info has of_node and fwnode members. This is
quite confusing as they are of the same semantics and it's tend
to have an issue if user assigns both. Luckily there is only a
single driver that does this and fix was sent today. Nevertheless
the series moves the client handling code to use fwnode and deprecates
the of_node member in the respective documentation.

Tomi, can you test this series + the patch we discussed earlier so it works as
expected?

In v2:
- covered i2c-core-slave.c where it makes sense
- covered i2c-core-of.c where it makes sense
- rebased on top of the latest code base

Andy Shevchenko (6):
i2c: core: Drop duplicate check before calling OF APIs
i2c: core: Unify the firmware node type check
i2c: core: Switch to fwnode APIs to get IRQ
i2c: core: Reuse fwnode variable where it makes sense
i2c: core: Do not dereference fwnode in struct device
i2c: core: Deprecate of_node in struct i2c_board_info
