There is no need to clear the ISP sink-pad crop and source-pad compose rectangles on release of the /dev/video# file. Both will be reset by atomisp_set_fmt() which is guaranteed to get called by atomisp_queue_setup() (if not called already) before another stream starts and thus before these selections are used again. Also the file injection support the comment talks about has long been dropped from the driver. Reviewed-by:

struct atomisp_platform_data only has a single subdevs member. Remove this struct and replace atomisp_get_platform_data() with atomisp_platform_get_subdevs(). Note atomisp_get_platform_data() and now atomisp_platform_get_subdevs() always succeed, so while at it also remove unnecessary error checking. Reviewed-by:

After removing the flash support frame_status now always is ATOMISP_FRAME_STATUS_OK aka 0. Drop frame_status tracking. This also means one less atomisp custom use for the vb2_buffer->reserved* fields (all custom use of these fields should be removed). While at it also remove the no longer used vf_frame pointer from struct atomisp_sub_device. Reviewed-by:

Remove the custom flash handling from the atomisp driver. There are only few Bay Trail / Cherry Trail devices with flash and if those will ever get supported then this should be done through the new standard include/linux/led-class-flash.h APIs instead of with atomisp specific custom APIs.

Drop the atomisp custom lm3554 flash driver, support for flash drivers using the custom atomisp flash interface is going to be removed from the atomisp driver. If flash supports for the lm3554 turns out to be necessary on some atomisp devices in the future then this should be re-implemented using the new include/linux/led-class-flash.h APIs. The atomisp specific lm3554 driver could still be usable as a reference for how to use / driver the lm3554 for a future re-implementation using standardized APIs, but for that it can be retrieved from the git history.

Change the single, unexpected user of CSI_PORT0_ID for (port = CSI_PORT0_ID; port < N_CSI_PORTS; port++) to for (port = 0; port < N_CSI_PORTS; port++) { matching all the other for-loops iterating over the ports in the same file. And remove the now fully unused input_port_ID_t enum type. Reviewed-by: -

The TPG support registers a v4l2-subdev for this, but this is not part of the media-controller graph in any way. After manually selecting the TPG as input using the s_input ioctl it does not work. Several supported sensors have their own working TPG and using the sensor's TPG means that the same data-flow is used as with actual sensors rather then the quite different data-flow from the ISP's builtin TPG. Remove the broken TPG support, when a test-pattern is needed for testing a sensor's TPG can be used. Using a sensor's TPG is actually better for testing since then the actual normal data-flow is being tested. Reviewed-by:

The atomisp driver now properly ensures s_power(1) is called before calling the set_fmt() callback, so this workaround is no longer necessary. Reviewed-by:

The media-controller core (__media_entity_setup_link()) already checks that the pads of the link are not streaming before calling the setup_link() pad-op so calling atomisp_pipe_check() is not necessary; and taking isp->mutex inside the setup_link() pad-op leads to a possible ABBA deadlock vs the media-device graph_mutex which in the case of the setup_link() pad-op is taken before calling the op, while in other scenarios the graph_mutex is taken after the isp->mutex.

Most sensor drivers report V4L2_FIELD_NONE as v4l2_mbus_framefmt.field value. Propagate this to the v4l2_mbus_framefmt for the CSI port to pass the link validation done by media_pipeline_start(). Keep the v4l2_mbus_framefmt.field for the source pad of the CSI port as V4L2_FIELD_ANY to match the ISP sink pad. Reviewed-by:

So far the CSI port sink and source pads have not had their fmt set at all, leaving things at the default of SBGGR8_1X8/0x0. This means that pipeline validation such as e.g. done when calling media_pipeline_start() will fail since the links to / from the CSI ports have different fmts on each end. Store a pointer to the CSI port v4l2-subdev in struct atomisp_input_subdev, and use this in atomisp_set_sensor_crop_and_fmt() to propagate the sensors new fmt after a successful set_fmt to the CSI port it is connected too. The input->csi_port pointer also allows simplifying atomisp_link_setup(). Reviewed-by:

Simplify the checking of the input argument to atomisp_s_input(): - Remove the check for input >= ATOM_ISP_MAX_INPUTS, input_cnt never is > ATOM_ISP_MAX_INPUTS so checking only that is sufficient - Remove the unnecessary camera local variable - Move the 2 invalid argument checks to above the atomisp_pipe_check() which checks if the pipe is busy or not Reviewed-by:

When switching input/sensor the s_power() callback must be called for old sensor drivers to power on the new sensor and power off the previous sensor. atomisp_s_input() already does this but atomisp_link_setup() did not do this. Add a new atomisp_select_input() helper which does this and use this in both atomisp_s_input() and atomisp_link_setup() for consistent behavior. Also make atomisp_link_setup() turn the sensor back off when a link gets disabled. Reviewed-by:

ATM the atomisp driver does not call s_power() at all when no s_input ioctl() is done by the application. This breaks older sensor drivers which rely on s_power() for power-management. Some drivers have worked around this, e.g. commit c5fafbad ("media: atomisp: gc0310: Power on sensor from set_fmt() callback") and commit b3118a94 ("media: atomisp: ov2722: Power on sensor from set_fmt() callback"), but this really should be fixed in the atomisp driver itself, so that all old drivers can work. A logical place to call s_power() would be from atomisp_start_streaming() / atomisp_stop_streaming(). But some older drivers, e.g. the atomisp-ov2722 driver already write mode related registers on set_fmt() instead of waiting on stream on. So the s_power(1) needs to happen at the first set_fmt(). Add an atomisp_s_sensor_power(..., 1) call just before calling set_fmt() for this. If the power was already enabled through e.g. a s_input ioctl atomisp_s_sensor_power() will skip calling the s_power() v4l2-subdev-op a second time. Reviewed-by:

Since the atomisp driver only supports 1 stream / only has 1 asd now, there is no longer a need to track which stream owns the sensor. So the asd owner-pointer of struct atomisp_input_subdev can be dropped, replace this with a simple camera_on boolean and add a new atomisp_s_sensor_power() helper which takes care of avoiding unbalanced s_power() subdev calls as well as takes care of handling the special -ENOIOCTLCMD return for subdevs which don't implement s_power().

V4L2_PIX_FMT_RGB32 is deprecated because its definition never made clear if the 4th byte was alpha data or unused. Instead either V4L2_PIX_FMT_ARGB32 or V4L2_PIX_FMT_RGBX32 should be used. V4L2_PIX_FMT_RGB32 internally is mapped to IA_CSS_FRAME_FORMAT_RGBA888 and ia_css_frame_format.h says that the alpha bits there are unused, so replace V4L2_PIX_FMT_RGB32 with V4L2_PIX_FMT_RGBX32.

Some userspace apps (e.g. libcamera) do not like it if the enum_fmts ioctl returns the same fmt twice. Drop the second "do not use" V4L2_PIX_FMT_UYVY entry for parallel sensors to fix this. The current atomisp code does not support anything other then raw bayer sensors anyways, so dropping this is not an issue. Signed-off-by:

The subtract in this condition is reversed. The ->length is the length of the buffer. The ->bytesused is how many bytes we have copied thus far. When the condition is reversed that means the result of the subtraction is always negative but since it's unsigned then the result is a very high positive value. That means the overflow check is never true. Additionally, the ->bytesused doesn't actually work for this purpose because we're not writing to "buf->mem + buf->bytesused". Instead, the math to calculate the destination where we are writing is a bit involved. You calculate the number of full lines already written, multiply by two, skip a line if necessary so that we start on an odd numbered line, and add the offset into the line. To fix this buffer overflow, just take the actual destination where we are writing, if the offset is already out of bounds print an error and return. Otherwise, write up to buf->length bytes.
