Regulators for iMX6 OV5640 MIPI camera on Nitrogen6x board

Question asked by hkh on Jul 2, 2014

There are calls in the OV5640 MIPI driver to set a few regulators (io, core, and analog), and I am not sure what these are for. Looking at the Nitrogen6x schematics I don't see any programmable regulator that feeds the MIPI connector.

 

#define OV5640_VOLTAGE_ANALOG           2800000
#define OV5640_VOLTAGE_DIGITAL_CORE     1500000
#define OV5640_VOLTAGE_DIGITAL_IO       1800000

 

The calls in questions are:

regulator_enable()

regulator_disable()

regulator_get()

regulator_set_voltage()

 

Could you tell me which regulators are being controlled by these calls?

 

Thanks,
