Summary: AD1980 not detected in svn trunk on BF548-EZKIT

Details:

using BF548-EZKIT defconfig and then manually enabling these options (because the defconfig is outdated and no longer selects things by default), booting up my rev 1.4 board is unable to detect the codec (i dont think there are any switch settings i need to check?).

ive attached my kernel config. here's the output during boot:
