Ander Conselvan de Oliveira March 11, 2015, 11:33 a.m. UTC
The tests exercise different combinations of enabling pipe B with modes
that require more than 2 lanes and then enabling pipe C.

v2: Added a couple more tests for different pipe transitions. (Ander)
    Use custom modes to make the test reliable. (Daniel)

Please add the test binary to .gitignore and add a short description
of the test using the IGT_TEST_DESCRIPTION macro.
