I wonder if we cannot use an array and fill it up before pumping it out through
i2c. something like:
struct configure_array{
u16 reg;
u16 val;
}
struct configure_array reg_config[]={
{OV3640_ISP_YOUT_H, 0x0},
...
};
Then
for (i=0;i< sizeof(reg_config)/sizeof(configure_array);i++) {
err = reg_write(reg_config[i].reg, reg_config[i].val);
if (err) {
/* do something */
}
}
Further, we have multiple sensors following CCI[1] - why not have a driver for
the same, it will simplify the entire process - ov3640, mt9p012 both follow the
spec at least.. dependency would be sensor -> cci dev->i2c framework.
