Add new ioctls to set and get subdev client capabilities. Client in this context means the userspace application which opens the subdev device node. The client capabilities are stored in the file handle of the opened subdev device node, and the client must set the capabilities for each opened subdev. For now we only add a single flag, V4L2_SUBDEV_CLIENT_CAP_STREAMS, which indicates that the client is streams-aware. The reason for needing such a flag is as follows: Many structs passed via ioctls, e.g. struct v4l2_subdev_format, contain reserved fields (usually a single array field). These reserved fields can be used to extend the ioctl. The userspace is required to zero the reserved fields. We recently added a new 'stream' field to many of these structs, and the space for the field was taken from these reserved arrays. The assumption was that these new 'stream' fields are always initialized to zero if the userspace does not use them. This was a mistake, as, as mentioned above, the userspace is required to zero the _reserved_ fields. In other words, there is no requirement to zero this new stream field, and if the userspace doesn't use the field (which is the case for all userspace applications at the moment), the field may contain random data. This shows that the way the reserved fields are defined in v4l2 is, in my opinion, somewhat broken, but there is nothing to do about that. To fix this issue we need a way for the userspace to tell the kernel that the userspace has indeed set the 'stream' field, and it's fine for the kernel to access it. This is achieved with the new ioctl, which the userspace should usually use right after opening the subdev device node. Signed-off-by:

Hans Verkuil authored
The initial field value of the format is ANY, which isn't allowed. Change to INTERLACED. VIDIOC_TRY_FMT will overwrite vv->last_field, which is an unwanted side-effect, so drop this. And finally vidioc_s_fmt_vid_cap didn't initialize vv->last_field correctly. Signed-off-by:

Document FCPVD found in RZ/G2L alike SoCs. FCPVD block is similar to FCP for VSP found on R-Car SoC's . It has 3 clocks compared to 1 clock on fcpv. Introduce new compatibles renesas,r9a07g044-fcpvd for RZ/G2{L,LC} and renesas,r9a07g054-fcpvd for RZ/V2L to handle this difference. The 3 clocks are shared between du, vspd and fcpvd. No driver changes are required as generic compatible string "renesas,fcpv" will be used as a fallback. Signed-off-by:Rob Herring <robh@kernel.org> Signed-off-by:

The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is (mostly) ignored and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. Trivially convert this driver from always returning zero in the remove callback to the void returning variant. Signed-off-by:
