Subject: [PATCH] media: i2c: imx290: Add support for imx327 variant
|
|
|
|
Should be upstream commit 3c3f66b8125a
|
|
|
|
Both sensors are quite similar. Their specs only differ regarding LVDS
|
|
and parallel output but are identical regarding MIPI-CSI-2 interface.
|
|
But they use a different init setting of hard-coded values, taken from
|
|
the datasheet.
