I will not block the patch for this: you are the maintainer and you can
test and check if this ok.
I would only to point to the discussion with Peng regarding the same
issue for the mx6sxsabresd. Peng confirmed that he would send a
following patch for enabling only the clocks are needed. Mybe you can
synchronize wit him.

ok, I admit that diggering into the DCD table requires too much effort.
What about to move to SPL code ? I have expected that new i.MX6 boards
will be moved to support SPL, but it looks like that most patches still
stick with DCD tables. A couple of Freescale's boards were already
ported to SPL and merged. Have you considered to use SPL ? If yes, which
are the reason to not support it ?

Is it required to call every time i2c_probe() ? Should be called only once ?

Why USB here and not in board_init ? It is not a problem because you set
only the pinmux, but if setup_usb() will be changed in future, it is

There was a clean-up patchset by Fabio - fsl_esdhc_initialize() prints
already a warning, you do not need a second one here.
