Zero for frosh admission, because there is no direct admission to L&S CS.
You would apply to L&S for frosh admission. If admitted, you need to complete CS 61A, 61B, and 70 with a 3.30 GPA to enter the L&S CS major. See https://eecs.berkeley.edu/academics/undergraduate/cs-ba .
http://www.universityofcalifornia.edu/infocenter/freshman-admissions-summary indicates that, for 2015, 46% of frosh applicants to Berkeley with HS GPA >= 4.20 (UC-weighted, yours is probably in the 4.3ish range if you took lots of UC-approved honors and AP courses in 10th-11th grades) were admitted. This is for the whole campus, not accounting for divisional differences (e.g. College of Engineering is generally more difficult and admits by major), but L&S is the largest division, so it should not be that different from the whole campus.
