Thanks for updating it. This series still hangs after loading
modules on beagleboard-x15:

[   26.679749] smps12: regulator_set_voltage: 3381
[   26.684529] smps12: regulator_set_voltage_unlocked:  3045
[   26.695616] smps12: _regulator_do_set_voltage: 2912
[   26.701275] smps12: regulator_set_voltage: 3381
[   26.706002] smps12: regulator_set_voltage_unlocked:  3045
[   26.712349] smps12: _regulator_do_set_voltage: 2912
[   26.719329] abb_mpu: regulator_set_voltage: 3381
[   26.724105] abb_mpu: regulator_set_voltage_unlocked:  3045

So it seems to be the abb_mpu where it hangs?

Regards,

Tony
