Hi Marco

This description seems odd to me. I'm guessing here:

Are we talking about a device which as been suspended? The PHY has
been left running because there is no suspend callback? Something then
triggers a resume. The bootloader then suspends the active PHY? Linux
then boots, detects its a resume, so does not touch the hardware
because there is no resume callback? The suspended PHY is then

Adding suspend/resume calls makes sense, i just don't follow the
commit message reasoning.
