OK, another example. The cameras supported in camlibs/jl2005c do not have

Hi Sakari,
I have a point with the pixel clock. During discussion we found that
pixel clock get/set is required for user space to do fine control over
the frame-rate etc. What if the user sets the pixel array clock which is
above the system/if bus clock? Suppose we are setting the pixel clock

This patch implements an i2c_gate_ctrl op for the cxd2820r. Thanks to Robert

Hi Harald,
Currently the controller chip on the BlackGold card is unsupported - I

Perhaps somebody else here knows the full story.

This patch fixes the remaining -ENOTTY fallout:
- The ENUM_FMT ops form a subset of the ops used with G/S/TRY_FMT, so list those
explicitly instead of using a macro.
- Extend the G/S/TRY_FMT ops test to the full set.
- Move all prio tests down to the correct switch cases.
- Fix some 'returns ENO

There were a several problems in this function:
1) Potential integer overflow in the comparison:
if (fio.write_len + fio.read_len > 1028) {
2) If the user gave bogus values for write_len and read_len then
returning -EINVAL is more appropriate than returning -ENOMEM.
3) wbuf was set t

This patch modifies the way autoclusters work when the 'foo' controls are
volatile if autofoo is on.
E.g.: if autogain is true, then gain returns the gain set by the autogain
circuitry.
This patch makes the following changes:
1) The V4L2_CTRL_FLAG_VOLATILE flag is added to let userspace know tha
