The .s_stream() and .link_validate() operations can't be called with a NULL src_sd, as subdev nodes are not registered before the async notifier completes. Remove the unneeded checks. Signed-off-by:

The imx7_csi_video_init_format() function instantiates a v4l2_subdev_format on the stack, to only use the .format field of that structure. Replace it with a v4l2_mbus_framefmt instance. Signed-off-by:

The radio device doesn't use vb2, thus calling vb2_video_unregister_device() which results in the following warning being printed on module unload.

When smscore_start_device() gets failed, the function smsusb_term_device() will be called and smsusb_device_t will be deallocated. Although we use usb_kill_urb() in smsusb_stop_streaming() to cancel transfer requests and wait for them to finish, the worker threads that are scheduled by smsusb_onresponse() may be still running.

Depending on which order userspace makes various v4l2 calls, the sensor might still be powered down when set_fmt is called. What should really happen here is delay the writing of the mode-related registers till streaming is started, but for now use the same quick fix as the atomisp_ov2680 / atomisp_gc0310 code and call power_up() from set_fmt() in combination with keeping track of the power-state to avoid doing the power-up sequence twice.

On ov2722_set_fmt() calls with format->which == V4L2_SUBDEV_FORMAT_TRY, ov2722_set_fmt() does not talk to the sensor, so there is no need to lock the dev->input_lock mutex in this case. Reviewed-by:

The comment claims the PWDN pin is active when pulled down in other words, it is /power-down so it needs to be driven high to get the sensor powered-up (not powered down) and flag is 1 when powering-up the sensor so the ! is wrong, drop it. This also matches with the schematics which I have which shows GPIO1 also enables a 3.3v line to the sensor-module which controls the privacy-LED and indeed before this patch the privacy LED was inverted from what it should be (and the sensor did not work).

The DSDT of all Windows BYT / CHT devices which I have seen has proper ACPI powermagement for the clk and regulators used by the sensors. So there is no need for the whole custom atomisp_gmin custom code to disable the ACPI pm and directly poke at the PMIC for this. Replace all the atomisp_gmin usage with using the new atomisp_register_sensor_no_gmin() / atomisp_unregister_subdev() helpers which allow registering a sensor with the atomisp code without using any of the atomisp_gmin power-management code. Note eventually these calls should be replaced by the standard v4l2_async_register_subdev_sensor() mechanism. But this first requires a bunch of work to the atomisp main code to make it set the necessary fwnodes up, similar to how drivers/media/pci/intel/ipu3/cio2-bridge.c does this. This has been tested on: -Trekstor Surftab duo W1 10.1, CHT, AXP288 PMIC, 2x ov2680 sensor -Asus T101HA, CHT, TI PMIC, 1x ov2680 sensor -MPMAN Converter 9, BYT, AXP288 PMIC, ov2680 back, gc0310 front sensor Reviewed-by:

Use devm_kzalloc() to allocate the sensor data struct. It is always free-ed as the last step of probe-error-exit or remove, so it can be devm-managed. This will make unwinding things easier when support is added to the ov2680 code to use standard GPIO APIs instead of the custom atomisp_gmin code. This also allows dropping the out_free label and use direct return on errors. This may seem like a functional change since the out_free label also did a v4l2_device_unregister_subdev() but at the 2 changed returns the device is not registered yet, so that always is a no-op and can be dropped.

Using dev as name for variables pointing to struct ov2680_device is a bit unfortunate choice. All the recently added / rewritten code is already using sensor for this, replace the remaining usages of "struct ov2680_device *dev" with "struct ov2680_device *sensor". Note the power_up()/power_down() related functions are not changed as these will be removed in one of the next patches. No functional changes. Reviewed-by:

3 fixes for the framesize list: 1. Drop modes < 640x480, these are made by significant cropping, leading to such a small remainig field-of-view that they are not really usable 2. 1616x1082 is presumably intended to be 1600x1080 + 16 pixels padding in both dimensions, but the height is wrong. Change this to 1616x1096. 3. The 800x600 mode is missing the 16 pixels padding and 720x592 is missing 16 pixels padding in its width and the 720x576 base mode is a mode with non square pixels, while the sensor has square pixels. Replace both with 768x576 + 16 pixels padding -> 784x592 Reviewed-by:
