V4L/DVB (11705): soc-camera: prepare for the platform driver conversion

2009-06-16T21:20:54Z

Add a platform driver to soc_camera.c. This way we preserve backwards compatibility with existing platforms and can start converting them one by one to the new platform-device soc-camera interface. Signed-off-by: Guennadi Liakhovetski Signed-off-by: Mauro Carvalho Chehab

V4L/DVB (11609): soc-camera: remove an extra device generation from struct soc_camera_host

2009-06-16T21:20:43Z

Make camera devices direct children of host platform devices, move the inheritance management into the soc_camera.c core driver. Signed-off-by: Guennadi Liakhovetski Signed-off-by: Mauro Carvalho Chehab

V4L/DVB (11607): soc-camera: add a free_bus method to struct soc_camera_link

2009-06-16T21:20:43Z

Currently pcm990 camera bus-width management functions request a GPIO and never free it again. With this approach the GPIO extender driver cannot be unloaded once camera drivers have been loaded, also unloading theb i2c-pxa bus driver produces errors, because the GPIO extender driver cannot unregister properly. Another problem is, that if camera drivers are once loaded before the GPIO extender driver, the platform code marks the GPIO unavailable and only a reboot helps to recover. Adding an explicit free_bus method and using it in mt9m001 and mt9v022 drivers fixes these problems. Signed-off-by: Guennadi Liakhovetski Acked-by: Eric Miao Signed-off-by: Mauro Carvalho Chehab

V4L/DVB (11030): soc-camera: add board hook to specify the buswidth for camera sensors

2009-03-30T15:43:21Z

Camera sensors have a native bus width say support, but on some boards not all sensor data lines are connected to the image interface and thus support a different bus width than the sensors native one. Some boards even have a bus driver which dynamically switches between different bus widths with a GPIO. This patch adds a hook which board code can use to support different bus widths.

V4L/DVB (11027): soc-camera: configure drivers with a default format at probe time

2009-03-30T15:43:21Z

Currently soc-camera doesn't set up any image format without an explicit S_FMT. According to the API this should be supported, for example, capture-example.c from v4l2-apps by default doesn't issue an S_FMT. This patch moves negotiating of available host-camera format translations to probe() time, and restores the state from the last close() on the next open(). This is needed for some drivers, which power down or reset hardware after the last user closes the interface. This patch also has a nice side-effect of avoiding multiple allocation anf freeing of format translation tables. Signed-off-by: Guennadi Liakhovetski Signed-off-by: Mauro Carvalho Chehab

V4L/DVB (11024): soc-camera: separate S_FMT and S_CROP operations

2009-03-30T15:43:21Z

As host and camera drivers become more complex, differences between S_FMT and S_CROP functionality grow, this patch separates them. Signed-off-by: Guennadi Liakhovetski Signed-off-by: Mauro Carvalho Chehab

V4L/DVB (10675): soc-camera: extend soc_camera_bus_param_compatible with more tests

2009-03-30T15:42:53Z

Add data signal polarity, mode, and bus-width tests to soc_camera_bus_param_compatible(). Signed-off-by: Guennadi Liakhovetski Signed-off-by: Mauro Carvalho Chehab

V4L/DVB (10141): v4l2: debugging API changed to match against driver name instead of ID.

2009-01-02T19:11:52Z

Since the i2c driver ID will be removed in the near future we have to modify the v4l2 debugging API to use the driver name instead of driver ID. Note that this API is not used in applications other than v4l2-dbg.cpp as it is for debugging and testing only. Should anyone use the old VIDIOC_G_CHIP_IDENT, then this will be logged with a warning that it is deprecated and will be removed in 2.6.30.

V4L/DVB (10093): soc-camera: add new bus width and signal polarity flags
