No, not to my knowledge. There are no settings for color output because it is fixed to GBGB/RGRG. I was looking a lot into this driver (I have few other problems with it, already few other patches posted) and I could not find a setting for this in datasheet. If you know the setting for the other color - can you point me to it?
And except the datasheet which mentions the specific format, the testing confirms it. With original color the pictures are pink/purple. With proper color, the pictures are correct (with more green color as expected for bayer).
Quoting the driver's start_streaming function:
/* Set Orientation be 180 degree */ ret = imx258_write_reg(imx258, REG_MIRROR_FLIP_CONTROL, IMX258_REG_VALUE_08BIT, REG_CONFIG_MIRROR_FLIP);I understand that you think it will replace the lines and columns and the first line will be RG, instead of GB.... or actually BG because it flips horizontal and vertical? So why does it not work?
Any chance your SoC capture interface performs this flipping on its own as well?
BTW, this nicely points that the comment around device_property_read_u32() for rotation is a little bit misleading :)
Are you referring to the comment below?
/* * Check that the device is mounted upside down. The driver only * supports a single pixel order right now. */ ret = device_property_read_u32(&client->dev, "rotation", &val); if (ret || val != 180) return -EINVAL;
What's misleading about it?
if (ret) { dev_err(&client->dev, "%s failed to set orientation\n", __func__); return ret; }Could it be you're taking pictures of pink objects? ;-)
I can send a few sample pictures taken with GStreamer (RAW8, not original RAW10)...
