OV5648 and GC2235 camera drivers?

Hey,

I have this tablet:
http://www.onda-tablet.com/onda-v975w-quad-core-win-8-tablet-9-7-inch-retina-screen-ram-2gb-wifi-32gb.html
which according to its BIOS has a GC2235 front camera and a OV5648 rear camera.

The DSDT for the device is here:
https://bugzilla.kernel.org/attachment.cgi?id=149331

Look for "Device (CAM2)" for the OV5648 camera, and "Device (CAM3)" for the GC2235 camera.

It looks like there are Android drivers for those devices:
https://github.com/NoelMacwan/Kernel-C6806-KOT49H.S2.2052/blob/master/drivers/media/platform/msm/camera_v2/sensor/ov5648.c
and:
http://dl.linux-sunxi.org/SDK/A80/A80_SDK_20140728_stripped/lichee/linux-3.4/drivers/media/video/sunxi-vfe/device/gc2235.c

I have no idea which framework the first one is using, but the second one looks like it could be used on an upstream Linux kernel (with some cleaning up...).

Does anyone know if somebody is working on support for those drivers, either upstream or in a staging tree somewhere?

Cheers
