hi, Jon:
thanks for your work! it is good to know that your brought up
MMP2(610) SoC with OV7670
I have some questions:
1) this driver is still based on cafe_ccic.c, as you said, we
can abstract the low level register function, and use soc_camera and
videofbu2 to manage the buff and state machine, how do you think ?
2) i2c_adapter, how about move this code to driver/i2c, then
ccic driver will become clean?
3) in mmp_driver.c, it has the sensor name, OV7670, we wish
that ccic driver do not need to aware of the sensor, also we need to
support front and back camera sensor cases.
Guennadi, what is your suggestions ?
great thanks!
