This patch allows LVDS PHYs to be configured through the generic functions and through a custom structure added to the generic union.
The parameters added here are based on common LVDS PHY implementation practices. The set of parameters should cover all potential users.

- Trivial tweaks.
- Drop Robert's R-b tag.
v3->v4:
- Add Robert's R-b tag.
v2->v3:

- struct phy_configure_opts_lvds - LVDS configuration set

What does it mean by bits per data lane and differential clock cycle?
- @differential_clk_rate: Clock rate, in Hertz, of the LVDS
differential clock.
- @lanes: Number of active, consecutive,
data lanes, starting from lane 0,
used for the transmissions.
- @is_slave: Boolean, true if the phy is a slave
which works together with a master
phy to support dual link transmission,
otherwise a regular phy or a master phy.
- This structure is used to represent the configuration state of a LVDS phy.

Where is the user of this new configuration? Can you post that patch for reference as well please
