[PATCH v2] Add v4l2 subdev driver for S5P MIPI-CSI receivers

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

 



Hello,

the following is a v4l2 subdev driver for MIPI-CSI2 receivers
available in S5PVx10 and EXYNOS4 SoCs. The MIPI-CSIS module 
(MIPI CSI Slave) works closely with the FIMC IP, i.e. it is its 
frontend for the MIPI CSI serial bus.

Other than that the following patch set moves the s5p-fimc driver
under Video Capture Devices in kconfig and adds a V4L2_MBUS_FMT_JPEG_1X8
media bus format.
To follow are patches converting s5p-fimc to the pad ops and
adding a media device for precisely managing all available FIMC and
MIPI CSIS entities and image sensors. However this still needs
a bit of work.

As usual, review comments are welcome!

Changes since v1:
 - added runtime PM support
 - conversion to the pad ops

The patch series contains:

 [PATCH 1/3] v4l: Add V4L2_MBUS_FMT_JPEG_1X8 media bus format
 [PATCH 2/3] v4l: Move S5P FIMC driver into Video Capture Devices
 [PATCH 3/3] v4l: Add v4l2 subdev driver for S5P/EXYNOS4 MIPI-CSI Receiver
