Fix default_value of ioctl(VIDIOC_QUERYCTRL)(id=V4L2_CID_3A_STATUS)
to AE operating and AWB operating, because both AE and AWB are
automatical adjustment mode by default.
Because the exposure time and ISO sensitivity are adjusted automatically
by default, the default value can not be defined.
So, return the value out of range as the default_value of
ioctl(VIDIOC_QUERYCTRL).
Because the ratio between API value and ISX019 register value
is 128 : 90 about HUE, some different API values become the
same register value.
So, store the value specified by application in setting,
and return the stored value in getting so that the gotten value
is the same as the setting value by application.
About IMGSENSOR_ID_EXPOSURE_AUTO, IMGSENSOR_ID_ISO_SENSITIVITY_AUTO,
and IMGSENSOR_ID_EXPOSURE_METERING, enumerations are defined.
So, control type should be not integer but integer menu.
About parameter whose register size is less than 4 bytes,
when transfer read value to API parameter, cast appropriately
to avoid the following problems.
- Read value includes garbage value
- Negative value becomes huge positive value
isx019 driver freezes by I2C access in the interrupt context.
This I2C access is intended to stop data output from FPGA.
Delete this I2C access for the following reasons.
- Data output from FPGA does not affect power consumption
- There are no problems in capture restart without data output stop
since restart is done by image data block first.
When the value that is out of range is specified in ioctl(VIDIOC_S_CTRL) and
ioctl(VIDIOC_S_EXT_CTRLS), returned value should be not EINVAL but ERANGE.
The driver is provided by Spresense SDK
ISX019 has the DOL-HDR feature, which combines images with different exposure so that
both bright and dark data of high-contrast subject can be viewed at the same time.
