The Image Sensor Controller driver includes two parts.
1) Driver code to implement the ISC function.
2) Device tree binding documentation, it describes how
to add the ISC in device tree.

Hi, all,
I intend to submit some v4l2 videobuf2 kernel patches. Would someone can tell
me which git I can clone the codebase in order to prepare the patches?

- other fixes
v2:
- allocate kthread for each channel instead of workqueue
- create tegra-csi as a separated V4L2 subdevice
- define all the register bits needed in this driver
- add device tree binding document
- update things according to Hans and Thierry's review.
