Do you have CONFIG_REGULATOR set in your .config? That seems to be missing
from arch/arm/configs/omap_ldp_defconfig.

Anybody with an LDP care to update the omap_ldp_defconfig? No LDP here.

For 3 & 4, I know Imre has the patches ready to go.. Imre, have they been
posted to the fb list?

This could be pretty easy now with the ASoC driver, anybody seen a driver
