Subject: [PATCH] media/i2c: Add a driver for the Sony IMX708 image
|
|
|
|
|
sensor
|
|
|
|
|
|
|
|
|
|
The imx708 is a 12MP MIPI sensor with a 16:9 aspect ratio, here using
|
|
|
|
|
two CSI-2 lanes. It is a "quad Bayer" sensor with all 3 modes offering
|
|
|
|
|
10-bit output:
|
|
|
|
|
|
|
|
|
|
12MP: 4608x2592 up to 14.35fps (full FoV)
|
|
|
|
|
1080p: 2304x1296 up to 56.02fps (full FoV)
|
|
|
|
|
720p: 1536x864 up to 120.12fps (cropped)
|
|
|
|
|
|
|
|
|
|
This imx708 sensor driver is based heavily on the imx477 driver and
|
|
|
|
|
has been tested on the Raspberry Pi platform using libcamera.
