I am failing in defining regulators for TLV320AIC32X4 driver in Device
tree, it requires ldoin, iov, dv, av. Following is the errors coming in
dmesg.
[ 16.607195] 2-0018 supply iov not found, using dummy regulator
[ OK ] Started Update UTMP about System Boot/Shutdown.
[ 16.773985] tilcdc 4830e000.lcdc: no encoders/connectors found
