Hi Anand,

Set P5V0 and vcc_3v3 power source to USB to always on
so that regulator should not enter in suspend state.

Neither of these two regulators can be controlled by Linux in any way
(there's no GPIO to turn them off, no PWM signal to change the output
voltage, etc.).
So can you please explain what this patch changes from a functional perspective?


Best regards,
Martin
