[PULL REQUEST] i2c for 5.5

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Linus,

I2C has mostly driver updates for you this time. The few noteworthy
changes are: the core has now support for analog and digital filters
with at91 being the first user, a core addition to replace the NULL
returning i2c_new_probed_device() with an ERR_PTR variant, and the pxa
driver has finally being moved to use the generic I2C slave interface.
We have quite a significant number of reviews per patch this time, so
thank you to all involved!

Please pull.

Thanks,

   Wolfram
