The MIPI D-PHY spec defines default values and boundaries for most of the
parameters it defines. Introduce helpers to help drivers get meaningful
values based on their current parameters, and validate the boundaries of
these parameters if needed.
These helpers and header are taken from Linux commit 9123e3a74ec7 ("Linux 5.9-rc1").

This framework is designed to provide a generic interface for PHY

layer of the protocols in the OSI model.
|
|
PHYs are commonly used for high speed interfaces such as Serial-ATA
|

or PCI express.

The API provides functions to initialize/deinitialize the

PHY, power on/off the PHY, and reset the PHY. It's meant to be as
