Currently, any exposure or gain changes are applied immediately to the sensor. That may lead to unexpected behavior if the sensor is streaming. In order to avoid that, use group hold registers to store new settings and use VBlank delay launch mode to apply them during vertical blanking. As we have 4 group holds that we can use for operations unrelated to embedded-data or statistics, we can use one group hold for each control: exposure, analog_gain, digital_gain and white balance gain. Also, forbid changing PWL related settings while streaming. Signed-off-by: Laurentiu Palcu <laurentiu.palcu@oss.nxp.com> Reviewed-by: Robert Chiras <robert.chiras@nxp.com>
