The initial registers sequence is only loaded at probe time. Afterward only the resolution and format specific register are modified. Care must be taken to make sure registers modified by one resolution setting are reverted back when another resolution is programmed. This was not done properly for the 720p case. Signed-off-by:

On some board it is possible that the sensor 'powerdown' and or 'reset' pin might be controlled by gpio instead of being tied. To implement we add pm_runtime support which will handle the power up/down sequence when it is available otherwise the sensor will be powered on at module insertion/probe and powered off at module removal. Now originally the driver assumed that the sensor would always stay powered and keep its register setting. We cannot assume this anymore, so every time we "power up" we need to re-program the initial registers configuration first. This was previously done only at probe time.

Based on recently found sensor configuration examples, it was discovered that when scaling and binning are used for the lower resolutions (i.e. 640x480, 320x240) the read offset has to be increased otherwise the image appears to be wrapped around. Signed-off-by:

Instead of individually depending on MEDIA_CAMERA_SUPPORT (or forgetting it), put all camera sensor, lens and flash drivers under MEDIA_CAMERA_SUPPORT as a whole. The lens VCM devices didn't use to do this, but make them depend on MEDIA_CAMERA_SUPPORT as well since there's no use for these devices without that in practice. Signed-off-by:

The driver stores crop rectangle settings supposed to be in line with hardware state in a device private structure. Since the driver initial submission, crop rectangle width and height settings are not updated correctly when rectangle offset settings are applied on hardware. If an error occurs while the device is updated, the stored settings my no longer reflect hardware state and consecutive calls to .get_selection() as well as .get/set_fmt() may return incorrect information. That in turn may affect ability of a bridge device to use correct DMA transfer settings if such incorrect informamtion on active frame format returned by .get/set_fmt() is used. Assuming a failed update of the device means its actual settings haven't changed, update crop rectangle width and height settings stored in the device private structure correctly while the rectangle offset is successfully applied on hardware so the stored values always reflect actual hardware state to the extent possible.

It is not clear what pixel format is actually configured in hardware on reset. MEDIA_BUS_FMT_YUYV8_2X8, assumed on device probe since the driver was intiially submitted, is for sure not the one.

Commit da298c6d ("[media] v4l2: replace video op g_mbus_fmt by pad op get_fmt") converted a former ov6650_g_fmt() video operation callback to an ov6650_get_fmt() pad operation callback. However, the converted function disregards a format->which flag that pad operations should obey and always returns active frame format settings. That can be fixed by always responding to V4L2_SUBDEV_FORMAT_TRY with -EINVAL, or providing the response from a pad config argument, likely updated by a former user call to V4L2_SUBDEV_FORMAT_TRY .set_fmt(). Since implementation of the latter is trivial, go for it. Fixes: da298c6d ("[media] v4l2: replace video op g_mbus_fmt by pad op get_fmt") Signed-off-by:

User arguments passed to .get/set_fmt() pad operation callbacks may contain unsupported values. The driver takes control over frame size and pixel code as well as colorspace and field attributes but has never cared for remainig format attributes, i.e., ycbcr_enc, quantization and xfer_func, introduced by commit 11ff030c ("[media] v4l2-mediabus: improve colorspace support"). Fix it. Set up a static v4l2_mbus_framefmt structure with attributes initialized to reasonable defaults and use it for updating content of user provided arguments. In case of V4L2_SUBDEV_FORMAT_ACTIVE, postpone frame size update, now performed from inside ov6650_s_fmt() helper, util the user argument is first updated in ov6650_set_fmt() with default frame format content. For V4L2_SUBDEV_FORMAT_TRY, don't copy all attributes to pad config, only those handled by the driver, then fill the response with the default frame format updated with resulting pad config format code and frame size.

Since its initial submission, the driver selects V4L2_COLORSPACE_JPEG for supported formats other than V4L2_MBUS_FMT_SBGGR8_1X8. According to v4l2-compliance test program, V4L2_COLORSPACE_JPEG applies exclusively to V4L2_PIX_FMT_JPEG. Since the sensor does not support JPEG format, fix it to always select V4L2_COLORSPACE_SRGB.

Commit 4f996594 ("[media] v4l2: make vidioc_s_crop const") introduced a writable copy of constified user requested crop rectangle in order to be able to perform hardware alignments on it. Later on, commit 10d5509c ("[media] v4l2: remove g/s_crop from video ops") replaced s_crop() video operation using that const argument with set_selection() pad operation which had a corresponding argument not constified, however the original behavior of the driver was not restored. Since that time, any hardware alignment applied on a user requested crop rectangle is not passed back to the user calling .set_selection() as it should be. Fix the issue by dropping the copy and replacing all references to it with references to the crop rectangle embedded in the user argument.

Add support for cec-notifier to the cec-gpio driver. This makes it possible to associate the CEC gpio pin with an HDMI connector. This feature was always documented in the cec-gpio bindings: Documentation/devicetree/bindings/media/cec-gpio.txt But support for the hdmi-phandle property was never actually implemented in this driver. This patch adds support for this property. It also fixes a few incorrect error returns in the probe() function, which skipped the call to cec_delete_adapter(). Tested on a Raspberry Pi 3B with a modified vc4 driver. Signed-off-by:

Since the uapi does not contain the num_ref_idx_active_override_flag, drivers for decoders that do not parse slices themselves don't know how to choose between the num_ref_idx_l[01]_default_active and the num_ref_idx_l[01]_active override fields. Instead, userspace must set the override fields to the default values if the slice does not have the num_ref_idx_active_override flag set. The drivers will then always enable the override internally and ignore the default fields completely. Clarify this requirement in the API documentation. Signed-off-by:

The hardware is capable to passing V4L2_FIELD_ALTERNATE to user-space. Allow users to request this field format but still default to using the hardware interlacer if alternating is not explicitly requested. Before this change a sensor providing data using alternate would be always combined to an interlaced frame. After this change the user can request to receive frames as alternate if the sensor provides it. Signed-off-by:
