* Qualcomm MSM EEPROM
|
|
|
|
EEPROM is an one time programmed(OTP) device that stores the calibration data
|
|
use for camera sensor. It may either be integrated in the sensor module or in
|
|
the sensor itself. As a result, the power, clock and GPIOs may be the same as
|
|
the camera sensor. The following describes the page block map, power supply,
|
|
clock, GPIO and power on sequence properties of the EEPROM device.
|
|
|
|
Required properties if probe happens from camera daemon:
|
|
- cell-index: eeprom hardware core index
|
|
- compatible :
|
|
- "qcom,eeprom"
|
|
- reg : offset of eeprom device registers.
|
|
- qcom,cci-master : should specify the cci core index that eeprom use.

|
|
this eeprom.
