In any statically initialized data structure, the compiler is going to zero any part which is not already explicitly initialized. While we can take that knowledge overboard and simply avoid initializing anything that needs to be zero, it's at least a good idea not to bother zeroing parts that we don't otherwise care about - like "reserved" fields which may change in the future. Avoiding initialization of those fields now also avoids possible conflict down the road. Signed-off-by:

This allows v4l2 control UI-s to update the inactive state (ie grey-ing out of controls) for slave controls when the master control changes. [Use __uvc_find_control() to find slave controls, as they're always located in the same entity as the corresponding master control] Signed-off-by:

Hans de Goede authored
Note the unused in this patch slave_ids addition to the mappings will get used in a follow up patch to generate control change events for the slave ctrls when their flags change due to the master control changing value. Signed-off-by:

This avoids the need for doing a forward declaration of __uvc_ctrl_get (which is a static function) in later patches in this series. Note to reviewers this patch does not change a single line of code, it just moves the function up in uvc_ctrl.c a bit. Signed-off-by:

Just like with ctrl events, drivers may want to get called back on listener add / remove for other event types too. Rather then special casing all of this in subscribe / unsubscribe event it is better to use ops for this. Signed-off-by:

This driver was severely broken. This patch makes it work again, and updates it to the latest V4L2 frameworks (except for videobuf2). It passes the v4l2-compliance tests and it now handles suspend/resume correctly. Several custom controls are replaced by new standard controls, only the USB_ALTERNATE control remains. Tested with the Hanse HVS-CM500PC USB microscope. Signed-off-by:

The et61x251 has been deprecated for a couple of releases now, as all devices it supports are also supported by gspca_etoms, and it has not seen any maintenance in years. So now it is time to remove it. Signed-off-by:

We can only control the clockdivider to control exposure on the pac7311, making our expo control coarse, switch to an autogain algorithm optimized for this. Signed-off-by:

Now that the pac7302 and pac7311 drivers are split, they no longer share there control settings, so there is no need to scale the controls to register values, instead make them reflect the registers directly. Signed-off-by:

It turns out that the flush to sensor command needs to be done per register bank. We were missing one such flush in set_exposure, causing exposure changes to only show up when another setting in the same bank also got changed. Signed-off-by:

The pac7302 and pac7311 driver still contains some comments from before they were separated, such as marking certain functions 7302 or 7311 only, with the new split drivers these make no sense, remove them. Also removed the empty/unused sd_stop0 function from pac7311.c Signed-off-by:

Allow users of gspca/autogain_functions.h to declare which of the autogain algoritms they are going to use. This allows us to remove the hacks from drivers which don't use coarse_grained_expo_autogain. Signed-off-by:

Prior to this patch the stk-webcam driver was enabling the vflip and mirror bits in the sensor by default. Which only is the right thing to do if the sensor is actually mounted upside down, which it usually is not. Actually we've received upside down reports for both usb-ids which this driver supports, one for an "ASUSTeK Computer Inc." "A3H" laptop with a build in 174f:a311 webcam, and one for an "To Be Filled By O.E.M." "Z96FM" laptop with a build in 05e1:0501 webcam. Signed-off-by:
