The Alvium camera is shipped with sensor + isp in the same housing. The camera can be equipped with one out of various sensor and abstract the user from this. Camera is connected via MIPI CSI-2. Most of the camera module features are supported, with the main exception being fw update. The driver provides all mandatory, optional and recommended V4L2 controls for maximum compatibility with libcamera References: - https://www.alliedvision.com/en/products/embedded-vision-solutionsSigned-off-by:

As a result of converting to the stream-aware state functions, commit bc0e8d91 ("media: v4l: subdev: Switch to stream-aware state functions") caused the sd pointer of the state passed to the v4l2_subdev_state_get_crop() function to be dereferenced. It however missed that the atmel-isi driver creates the v4l2_subdev_state instance on the stack (which it shouldn't do, but that's a separate problem), without initializing the sd field. This results in a null pointer dereference. Fix it by initializing the sd field. Fixes: bc0e8d91 ("media: v4l: subdev: Switch to stream-aware state functions") Signed-off-by:

Supported media bus codes on the resizer sink pad are identical to the ISP source pad. The .enum_mbus_code() handler thus delegates the enumeration to the ISP's operation. This is problematic for two reasons: - Format enumeration on the ISP source pad is dependent on the format configured on the ISP sink pad for the same subdev state (TRY or ACTIVE), while format enumeration on the resizer sink pad should return all formats supported by the resizer subdev, regardless of the ISP configuration. - Delegating the operation involves creating a fake v4l2_subdev_state on the stack to pass to the ISP .enum_mbus_code() handler. This gets in the way of evolution of both the ISP enumeration handler and, more generally, the V4L2 subdev state infrastructure. Fix those two issues by implementing format enumeration manually for the resizer. Link: https://lore.kernel.org/r/20231126020948.2700-1-laurent.pinchart@ideasonboard.comReviewed-by:

In rkisp1_isp_stop() and rkisp1_csi_disable() the driver masks the interrupts and then apparently assumes that the interrupt handler won't be running, and proceeds in the stop procedure. This is not the case, as the interrupt handler can already be running, which would lead to the ISP being disabled while the interrupt handler handling a captured frame. This brings up two issues: 1) the ISP could be powered off while the interrupt handler is still running and accessing registers, leading to board lockup, and 2) the interrupt handler code and the code that disables the streaming might do things that conflict. It is not clear to me if 2) causes a real issue, but 1) can be seen with a suitable delay (or printk in my case) in the interrupt handler, leading to board lockup.

In all known platforms the ISP has dedicated IRQ lines, but for some reason the driver uses IRQF_SHARED. Supporting IRQF_SHARED properly requires handling interrupts even when our device is disabled, and the driver does not handle this. To avoid adding such code, and to be sure the driver won't accidentally be used in a platform with shared interrupts, let's drop the IRQF_SHARED flag.

The driver always enables the clocks at probe() and disables them only at remove(). It is not clear why the driver does this, as it supports runtime PM, and enables and disables the clocks in the runtime resume and suspend callbacks. Also, in the case runtime PM is not available, the driver calls the resume and suspend callbacks manually from probe() and remove(). Drop the unnecessary clock enable, thus enabling the clocks only when actually needed.
