Everyone:

This series contains various improvements (at least in my mind) and
fixes that I made to tc358767 while working with the code of the
driver. Hopefuly each patch is self explanatory.

Feedback is welcome!

Thanks,
Andrey Smirnov

    - Collected Reviewed-bys from Andrzej
    
    - Dropped explicit check for -ETIMEDOUT in "drm/bridge: tc358767:
      Simplify polling in tc_main_link_setup()" for consistency

    - AUX transfer code converted to user regmap_raw_read(),
      regmap_raw_write()

Changes since [v2]:

      tc_main_link_setup()" and "drm/bridge: tc358767: Simplify
      polling in tc_link_training()" changed to use tc_poll_timeout()
      instead of regmap_read_poll_timeout()
