Subject: [PATCH v6 00/15] tc358767 driver improvements

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

Changes since [v5]:

    - Fixed regression in "drm/bridge: tc358767: Add support for
      address-only I2C transfers" that broke EDID reading

    - Moved said patch to be the last in case it is still causing
      problems and needs to be dropped

Changes since [v4]:

    - tc_pllupdate_pllen() renamed to tc_pllupdate()

    - Collected Reviewed-bys from Andrzej for the rest of the series

Changes since [v3]:

    - 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]:

    - Patchset rebased on top of v4 of Tomi's series that recently
      went in (https://patchwork.freedesktop.org/series/58176/#rev5)
      
    - AUX transfer code converted to user regmap_bulk_read(),
      regmap_bulk_write()

Changes since [v1]:

    - Patchset rebased on top of
      https://patchwork.freedesktop.org/series/58176/
      
    - Patches to remove both tc_write() and tc_read() helpers added

    - Patches to rework AUX transfer code added

    - Both "drm/bridge: tc358767: Simplify polling in
      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()
