Since it is optional, controlling the reset pin is clearly not
something for the TC6 core.

However, i doubt having an external application controlling the reset
is a good idea. You don't want to reset during operation. So to me,
this reset should be controlled by the driver. I tend to agree, that
actually performing a reset is optional, but i would expect the driver
to ensure the device is taken out of reset during probe, if the power
on default of the board is to hold it in reset.
