Since this series does not add any support for SATA, do we really want to
modify the SATA device tree binding?

I know that device tree describes the hardware, but if there is no software
that makes use of this, the SATA DT binding change feels a bit unnecessary.

Do we perhaps want to defer modifying the SATA DT binding change until the
corresponding change in software is added?


Kind regards,
Niklas
