Subject: [PATCH] media: i2c: imx290: Implement HBLANK and VBLANK
|
|
controls
|
|
|
|
Upstream commit 0c3b56c905e3.
|
|
|
|
Add support for the V4L2_CID_HBLANK and V4L2_CID_VBLANK controls to the
|
|
imx290 driver. Make the controls read-only to start with, to report the
|
|
values to userspace for timing calculation.
