# Leopard Imaging LI-M021C-MIPI Stereo-Optic Cameras
## Kernel Changes
The source code we have modified or added and is pertinent to these cameras is in the following files:
* controls-utility.sh
* hardware/nvidia/platform/t18x/common/kernel-dts/t18x-common-platforms/tegra186-tx2-spiri-camera-base.dtsi
* hardware/nvidia/platform/t18x/common/kernel-dts/t18x-common-platforms/tegra186-tx2-spiri-camera.dtsi

All these modifications and additions are part of the Spiri Mu kernel, and are represented by symbolic links from this repository into https://git.spirirobotics.com/Spiri/mu_kernel_sources, with the exception of the controls-utility.sh script, which is transferred in the spiri_scripts folder of the rootfs.
## Cameras setup
The camera sensors should be conencted to a ConnectTech's Elroy board.

#### Kernel Changes
The Driver for the MT9M021 cameras consists on the following structure, that adds the DTB and Kernel sources, along with its Makefiles that lead its portability to a Kernel source.
```bash
.
├── hardware

│ └── platform

```
In order to add the Driver to the Kernel, the following reference Kernel files are patched for adding custom controls that the camera implements.
* kernel/nvidia/drivers/media/platform/tegra/camera/camera_common.c
* kernel/nvidia/drivers/media/platform/tegra/camera/tegracam_ctrls.c
* kernel/nvidia/include/media/camera_common.h
* kernel/nvidia/include/media/tegra-v4l2-camera.h
