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"
José Roberto de Souza (1):
i2c: designware: wait for disable/enable only if necessary
Lucas De Marchi (2):
i2c: designware: detect when dynamic tar update is possible
i2c: designware: do not disable adapter after transfer
