Hi,
On insmod'ing alsa modules for i.MX53 QSB, I get the following error:
root@freescale-qsb:/lib/modules/2.6.38.8+# modprobe snd-soc-sgtl5000
snd_soc_instantiate_card:Entry
snd_soc_instantiate_card:Entry
soc_probe_dai_link:Entry
soc_probe_codec: Probing for card sgtl5000-audio
sgtl5000_enable_regulators:Entry
_regulator_get: devname = 1-000a
sgtl5000 1-000a: regulator_bulk_get [for (null)]: Failed to get supply
'VDDA': -19
sgtl5000_enable_regulators: regulator_bulk_get err!!!
print_constraints: 1-000a: 1200 mV normal
_regulator_get: devname = 1-000a
sgtl5000 1-000a: regulator_bulk_get [for (null)]: Failed to get supply
'VDDA': -19
sgtl5000 1-000a: Failed to request supplies:1 -19
sgtl5000 1-000a: asoc: failed to probe CODEC sgtl5000.1-000a: -19
asoc: failed to probe codec sgtl5000.1-000a
asoc: failed to instantiate card sgtl5000-audio: -19
On adding more printks, I realize that "_regulator_get" function is
failing(not able to find supply VDDA).
The statically built module gives no such errors. Can someone give some
info on this?
Regards,
maas
