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

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
