Implementing V4L2_CID_PIXEL_RATE is required for sensor drivers used with the OMAP3 ISP. The ISP driver needs to know the pixel rate on the ISP sink to configure the hardware. This was previously done with a platform callback, the ISP now queries the sensor directly using the V4L2_CID_PIXEL_RATE control. As you've pulled the ISP change for v3.5, I'd like these 3 patches to get in v3.5 as well to avoid regressions. > > --- > > > > The following changes since commit e89fca923f32de26b69bf4cd604f7b960b161551: > > [media] gspca - ov534: Add Hue control (2012-05-14 09:48:00 -0300) > > > > are available in the git repository at: > > ssh://linuxtv.org/git/sailus/media_tree.git media-for-3.5 > > > > Laurent Pinchart (3): > > mt9t001: Implement V4L2_CID_PIXEL_RATE control > > mt9p031: Implement V4L2_CID_PIXEL_RATE control > > mt9m032: Implement V4L2_CID_PIXEL_RATE control > > > > drivers/media/video/mt9m032.c | 13 +++++++++++-- > > drivers/media/video/mt9p031.c | 5 ++++- > > drivers/media/video/mt9t001.c | 13 +++++++++++-- > > include/media/mt9t001.h | 1 + > > 4 files changed, 27 insertions(+), 5 deletions(-) -- Regards, Laurent Pinchart -- 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
