Subject: [PATCH] media: i2c: imx477: Fix for long exposure limit
|
||
|
|
calculations
|
||
|
|
|
||
|
|
Do not scale IMX477_EXPOSURE_OFFSET with the long exposure factor during
|
||
|
|
the limit calculations. This allows larger exposure times, and does seem to be
|
||
|
|
what the sensor is doing internally.
