[PATCH 0/2] i2c: recovery: add bus_free callback

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

 



Add a new callback for IP cores which cannot report SDA directly but only a
'bus free' state. Implement this for the Renesas R-Car driver.

It has been tested with a Renesas Lager board (R-Car H2).

A branch (with further improvements) can be found here:

git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux.git renesas/i2c/recovery/write-byte-fix

Looking forward to comments.

Kind regards,

   Wolfram
