Hi,
Currently the Jetson TK1 is failing to get regulators for MMC with at least my regulator tree and probably -next also due to:
[ 1.665750] as3722 4-0040: AS3722 with revision 0x1 found [ 1.682945] +VDDIO_SDMMC3: failed to get the current voltage(-22) [ 1.689135] as3722-regulator as3722-regulator: regulator 13 register failed -22 [ 1.697593] as3722-regulator: probe of as3722-regulator failed with error -22
The get voltage operation here is just a simple mapping of a bitfield in the regmap which suggests that the underlying problem is somewhere further down the stack like the MFD or I2C drivers. The error is -EINVAL which suggests something like the register not being marked as readable but the _VOLTAGE_REG registers appear to be marked as readable in the MFD.
