As long as the i2c-list is on cc, they will show up in patchwork and
then I'll have the patches. All fine here.

Awesome, thanks for testing this series.

Looks like I forgot to CC Wolfram. CC'ing now on this cover letter, let
me know if you also need the individual patches.

[PATCH v3 0/3] i2c: designware: improve performance for transfers

[Lucas De Marchi]

This can be considered a v3 of "i2c: designware: do not disable adapter after
transfer". Differences are:

- Now there's a first patch that does not depend on IC_TAR being dynamically
  enabled/disabled: it just doesn't wait for the state change when not 
needed.

- We added a patch that allows detecting if HW supports the dynamic TAR 
updates

- In the last patch the bits were changed as suggested by Jarkko.

- This is tested on BayTrail and CherryTrail, both of them returning true 
for
  "dynamically update TAR"
