Camera board • Re: imx462 banding

Small update. I pulled the 6.6 kernel myself and applied your PR but again got the vertical band artifact.

Now I made a small adjustment:

Code:

        //cci_write(imx290->regmap, IMX290_FR_FDG_SEL, 0x01, &ret);//cci_write(imx290->regmap, IMX290_FR_FDG_SEL, 0x11, &ret);u8 val = IMX290_FRSEL_60FPS;if (hcg_mode) {val |= IMX290_FDG_HCG;} else {val |= IMX290_FDG_LCG;}cci_write(imx290->regmap, IMX290_FR_FDG_SEL, val, &ret);

And now the vertical band is gone. I can also adjust conversion gain at runtime. Underneath a comparison, 100ms shutter, gain 50.

cci_write(imx290->regmap, IMX290_FR_FDG_SEL,  IMX290_FRSEL_60FPS | hcg_mode ?IMX290_FDG_HCG : IMX290_FDG_LCG, &ret);

cci_write(imx290->regmap, IMX290_FR_FDG_SEL,IMX290_FRSEL_60FPS | (hcg_mode ? IMX290_FDG_HCG : IMX290_FDG_LCG));
