Dear Linux-media group I am a newbie and have recently started working on integration of a new camera sensor MT9M112 sensor with OMAP ISP Camera subsystem on a OMAP 3530 based custom board. So I checked in mainline kernel if driver is available for this camera sensor and I found it in the Linux/driver/media/video/mt9m11.c, this supports both MT9M111 and MT9M112. It is based on SoC-Camera framework. But unfortunately this is not compatible with OMAP 35xx Camera ISP subsystem as OMAP camera ISP subsystem is based on V4L2-INT. Also I got know that there are there are 3 different frameworks for camera sensor drivers in Linux a. V4L2-INT is deprecated but currently supported by OMAP35xx ISP Linux BSP b. SoC-Camera is also deprecated. c. Sub-Device is the current architecture supported from Open source community 1. Is this understanding correct ? 2. Since V4L2-INT and SoC-Camera frameworks are deprecated, can you please let me know the roadmap for Sub-Device framework ? 3. What is the best option/recommendation from community for me to integrate MT9M112 with Camera ISP system on OMAP 3530 based board ? 4. And lastly are there any other different camera sensors which have Sub-Device based drivers available in Mainline Linux? Thanks & best regards Manjunathan For your reference : Below are some references that I found on the internet/mailing list while researching on this. These are extra information on OMAP's Camera ISP subsystem implementation on Linux and SoC camera. As per the following websites/mailing lists, it seems that we there is no direct way to integrate SoC camera framework based drivers with OMAP and SoC CAM is deprecated. 1) http://processors.wiki.ti.com/index.php/OMAP3_GIT_Linux_Kernel#Video_Capture 2) http://www.archivum.info/video4linux-list@xxxxxxxxxx/2008-08/00125/Re:-%5BPATCH-v2%5D-soc-camera:-add-API-documentation.html ----------- extract from #2 mailing list dated August 2008 ---------------- ...... ..... I've been thinking it could make sense to unify v4l2-int-if and SoC camera efforts in longer term. Although the approach in SoC camera is somewhat different than in v4l2-int-if they share some similarities. V4l2-int-if tries to define common set of commands for commanding different hardware devices that make one V4L2 device, e.g. /dev/video0. SoC camera, OTOH, is a hardware-independent camera driver that can interface with different camera controllers and image sensors. Interestingly, the concepts used in v4l2-int-if and SoC camera are quite similar. Roughly equivalent pieces can be found easily: v4l2-int-if + OMAP 3 camera SoC camera OMAP 3 camera driver (int if master) SoC camera driver OMAP 3 ISP driver host sensor (int if slave) device lens (int if slave) flash (int if slave) Control flow: SoC camera | \ | \ | \ | \ host device OMAP 3 camera driver | | | \ | | | \ | | | \ | | | \ | sensor lens flash | | | | | machine/platform specific code | / | / | / | / | / ISP ------------------------------end of the extract from mailing list------------------------------------------- -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
