2 small changes to input device error handling: 1) Make it fatal when we fail to create an input device (it is either this or add checks for gspca_dev->input_dev being NULL in a lot of places) 2) Since we allow gspca_input_create_urb() to fail everywhere we call it, and thus never check its return value, make it void.

My experience with fixing up the controls for the PAS sensors in sonixb, has lead me to re-investigate the exposure control for the pac7302. I've now found a regular exposure register in register bank 3 (which seems to be the sensor registers bank), and with this added a proper fine grained exposure control. This patch also updates the do_autogain function to work properly with this new finer grained control. Signed-off-by:

In 640x480, if the reg11 has less than 4, the image is unstable (the bridge goes into a higher compression mode which we have not reverse engineered yet). Signed-off-by:

Some sensors only allow controlling the exposure by changing the clockdiv, which means that exposure takes pretty large jumps (for example when going from a div of 1 to 2, the exposure doubles). Use 2 different entries in the controls array for these 2 different types of exposure (always disabling one), and; Add a new autogain algorithm for the coarse exposure case, which normally changes the gain setting, only touching the exposure setting if the desired luminance cannot be reached with gain, and after an exposure change once more first tries gain, etc. Thus avoiding exposure changes, and the resulting oscilation because of the huge steps these exposure controls take.

This is a slightly modified version of Eric Anderson's original patch for the Sony Giga Pocket board. It has been updated to apply to the latest ivtv driver version by Hans Verkuil <hverkuil@xs4all.nl> and Andy Walls <awalls@radix.net>. Also Andy Walls modified the patch to use a new Sony BTF-Pnx01Z tuner entry based on Eric Anderson's experimental findings for the bandswitch. >From Eric Anderson's original email: 1. The tuner on the card doesn't seem to match any standard ones. I modified an existing tuner entry. Ideally a new tuner entry should be created. (The only difference from the one I modified is that the low-to-mid range frequency cut-off is slightly different, as are the bit config settings.) 2. It wasn't obvious how to choose a second audio input other than using "radio" as an option. Basically there's two GPIO audio inputs. Using radio allowed me to avoid major restructuring to the code. (perhaps other cards don't have this often...) 3. It's not clear that there's a mute setting that works. Not sure why. 4. I haven't had a chance to test the two Svideo inputs. I set them to COMPOSITE1 and SVIDEO2, but I'm not sure those are the correct settings. The standard composite video inputs seem to work. Signed-off-by:

ivtv_api_get_data() was performing more PCI MMIO than needed, resulting often in it accounting for more than half the total time spent in ivtv_irq_handler(). Now it only reads at most 7 of the 16 mailbox data words over the PCI bus, and in some instances only 2 or 3 data words as needed. Signed-off-by:

We know that the 300msec settling time after starting the digitizer is only really needed when the digitizer is a SAA7115. So if we're not using a SAA7115, skip the delay. Signed-off-by:

After implementing a 300msec wait between digitizer start and encoder start, it has been determined that we don't need to wait quite as long before configuring the encoder. This reduces the wait period from 100msec back to 50msec. Signed-off-by:
-
Mike Isely authored
Martin Dauskardt <martin.dauskardt@gmx.de> has determined that the encoder has a much better chance of starting cleanly if we deliberately hold off starting it util the video digitizer has had a chance to run for at least 300msec first. These changes implement an enforced 300msec wait in the state machine that orchestrates streaming start / stop. Signed-off-by:

The media spec contains several errors in the description of the I/O streaming ioctls, in particular with respect to the userptr I/O method. The most important change is that you really need to set count and index in v4l2_requestbuffer and v4l2_buffer when dealing with user pointer streaming. Signed-off-by:

When the saa7111 driver was merged into saa7115 several bugs were introduced, in particular with the saa7111a support as is used in the mxb.c driver. This patch fixes the saa7111a support. This was tested with the mxb driver. Signed-off-by:

v4l2_device_register needs to be called before the i2c subdevs are loaded. However, it was called afterwards in the saa7146 driver. This caused an oops when loading the mxb and hexium drivers. The vv_init function is now split into two: one registers the v4l2_device, the other does the rest of the initialization. The three drivers that depend on this have been updated to call the new vv_devinit function. Thanks to Michael Hunold for reporting this. Signed-off-by:

When setting a control, the V4L2 specification requires drivers to either clamp the control value to the [minimum, maximum] range or return the -ERANGE error. Fix the driver to clamp control values to the valid range in uvc_ctrl_set() and make sure the value differs from the minimum by an integer multiple of step. Signed-off-by:
