I have solved the above errors & commented out aic32x4_setup_regulators function. after these changes following errors are coming [ 18.295122] davinci_evm sound: ASoC: CODEC DAI hdmi-hifi not registered [ 18.555250] davinci_evm sound: snd_soc_register_card failed (-517) On Wed, Aug 19, 2015 at 7:00 PM, Maxim Podbereznyy <[email protected]> wrote: > I think these regulators are not necessary because you supply them in > hardware anyway.
