[PATCH v2 0/4] Support of MIPI CSI-2 for A83T

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This series adds the support for the MIPI CSI-2 controller for the A83T SoC.
The CSI controller is the same as the V3s SoC that's why I put the A83T
MIPI CSI-2 driver in sun6i-csi.
My work is based on the Allwinner BSP for A83T and also on MIPI CSI-2
specification for the A83T given by Allwinner.

Total for sun6i-video device /dev/video0: 45, Succeeded: 45, Failed: 0, Warnings: 0

Changes since V1:
- Add more details in the cover letter.
- Add a test to get the clocks to avoid an error for the platform without MIPI
CSI-2.
- Add more details in the register assignations.
- Removed the support of multiple virtual channels because there is only one
channel support in the CSI driver.
