V4L/DVB (11373): v4l2-common: add explicit v4l2_device pointer as first arg to new_(probed)_subdev

2009-04-07T00:44:24Z

The functions v4l2_i2c_new_subdev and v4l2_i2c_new_probed_subdev relied on i2c_get_adapdata to return the v4l2_device. However, this is not always possible on embedded platforms. So modify the API to pass the v4l2_device pointer explicitly. Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

V4L/DVB (11367): v4l2-common: remove legacy code

2009-04-07T00:44:20Z

Now that all drivers are converted to v4l2_subdev we can remove legacy code in v4l2-common. Also move the documentation of the internal API to v4l2-subdev.h where it really belongs. Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

V4L/DVB (11351): v4l: use usb_interface for v4l2_device_register

2009-04-07T00:43:59Z

If usb_interface.dev is used as dev parameter for v4l2_device_register v4l2_dev.name contains the v4l driver/module name and usb device and interface instead of a simple "usb x-y". It also matches the recommendation to set the parent devices for usb drivers. Signed-off-by: Janne Grunau Signed-off-by: Mauro Carvalho Chehab

V4L/DVB (11321): pxa_camera: Redesign DMA handling

2009-04-07T00:43:45Z

The DMA transfers in pxa_camera showed some weaknesses in multiple queued buffers context : - poll/select problem The bug shows up with capture_example tool from v4l2 hg tree. The process just "stalls" on a "select timeout". - multiple buffers DMA starting When multiple buffers were queued, the DMA channels were always started right away. This is not optimal, as a special case appears when the first EOF was not yet reached, and the DMA channels were prematurely started. - Maintainability DMA code was a bit obfuscated. Rationalize the code to be easily maintainable by anyone. - DMA hot chaining DMA is not stopped anymore to queue a buffer, the buffer is queued with DMA running. As a tribute, a corner case exists where chaining happens while DMA finishes the chain, and the capture is restarted to deal with the missed link buffer. This patch attemps to address these issues / improvements. create mode 100644 Documentation/video4linux/pxa_camera.txt Signed-off-by: Robert Jarzmik Signed-off-by: Guennadi Liakhovetski Signed-off-by: Mauro Carvalho Chehab

V4L/DVB (11044): v4l2-device: add v4l2_device_disconnect

2009-03-30T15:43:22Z

Call v4l2_device_disconnect when the parent of a hotpluggable device disconnects. This ensures that you do not have a pointer to a device that is no longer present. Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab
