In addition to Chapter 3 (i.MX 6 Series Layout Recommendations) of the "Hardware Development Guide

for i.MX 6...", please refer to the next document :

For camera signals also no specific recommendation is there.

Kindly send the guidelines for camera too.

In addition to general high frequency design recommendations please refer to

Annex B (Interconnect Design Guidelines) of MIPI Alliance Specification for

D-PHY (Version 1.00.00 – 14 May 2009).
