UC gives credit units for AP scores as described here:
http://admission.universityofcalifornia.edu/counselors/exam-credit/ap-credits/
Note: multiply by 2/3 for Berkeley and Merced, since the given numbers are for quarter units. Credit units may be applied to the 120 units needed to graduate, unless cancelled by taking a duplicating course.
Subject credit for AP scores at UCB L&S is limited:

Note that the L&S 7-course breadth requirement cannot be fulfilled with AP credit.
In addition, some AP scores may be used to fulfill requirements for some L&S majors. You need to check the major department web site for its AP score policy. Examples:
