Which version of the codec do you have? I have:
[ 0.370000] sgtl5000 0-000a: sgtl5000 revision 17
[ 0.370000] sgtl5000 0-000a: asoc: failed to probe CODEC sgtl5000.0-000a: -22
[ 0.380000] asoc: failed to instantiate card mxs_sgtl5000: -22
The failure is because CONFIG_REGULATOR is not set and it thus fails in the
#else /* CONFIG_REGULATOR */
static int ldo_regulator_register(struct snd_soc_codec *codec,
struct regulator_init_data *init_data,
(I can patch it to load properly, but well...)
Proper regulator support for mxs is not in mainline yet. Is that
planned? How do you do it?
