The reset-gpios is described as xshutdown-gpios on the required properties, as it is on the driver. Despite that, the device tree example set the property 'reset-gpios' instead of the property 'xshutdown-gpios'. Therefore, this patch updates the example to match the property specified on the driver. Acked-by:

The Hantro G2 video decoder block sits behind an IOMMU. The device tree binding needs a property to reference it. Without a reference for the implementation to properly configure the IOMMU, it will fault and cause the video decoder to fail. Add an "iommus" property for referring to the IOMMU port. The master ID in the example is taken from the IOMMU fault error message on Linux, and the number seems to match the order in the user manual's IOMMU diagram.

This driver was until the previous patch unused in the kernel and depended on platform data that no board was defining. As no users can be proven to exist, delete the driver.

The driver has an option to pass in GPIO numbers from platform data but this is not used in the kernel so delete this and the whole platform data mechanism. Get GPIO descriptors using the standard API and simplify the code, gpiolib will handle any inversions.

In preparation for FORTIFY_SOURCE performing run-time destination buffer bounds checking for memcpy(), specify the destination output buffer explicitly, instead of asking memcpy() to write past the end of what looked like a fixed-size object. Notice that raw_frame is a pointer to a structure that contains flexible-array member rawframe[]: drivers/media/usb/pwc/pwc.h: 190 struct pwc_raw_frame { 191 __le16 type; /* type of the webcam */ 192 __le16 vbandlength; /* Size of 4 lines compressed (used by the 193 decompressor) */ 194 __u8 cmd[4]; /* the four byte of the command (in case of 195 nala, only the first 3 bytes is filled) */ 196 __u8 rawframe[]; /* frame_size = H / 4 * vbandlength */ 197 } __packed; Link: https://github.com/KSPP/linux/issues/200Signed-off-by:Gustavo A.

On receiving last buffer driver puts MFC to MFCINST_FINISHING state which in turn skips transferring of frame from SRC to REF queue. This causes driver to stop MFC encoding and last frame is lost. This patch guarantees safe handling of frames during MFCINST_FINISHING and correct clearing of workbit to avoid early stopping of encoding.

Stop parsing upstream neighbors' device-tree endpoints to retrieve the media bus configuration. Instead use the get_mbus_config op and throw an error if the upstream subdevice does not implement it. Also drop the corresponding TODO entry and the now unused imx_media_get_pad_fwnode() function. Signed-off-by:

Use dma_set_mask_and_coherent() instead of unrolling it with some dma_set_mask()+dma_set_coherent_mask(). Moreover, as stated in [1], dma_set_mask() with a 64-bit mask will never fail if dev->dma_mask is non-NULL. So, if it fails, the 32 bits case will also fail for the same reason. Simplify code and remove some dead code accordingly. [1]: https://lkml.org/lkml/2021/6/7/398Signed-off-by:

Commit 5441e9da ("[media] s5p-mfc: Core support for MFC v7") which adds mfc v7 support for Exynos3250 and use the same compatible string as used by Exynos5240 but both the IPs are a bit different in terms of IP clock. Add variant driver data based on the new compatible string "samsung,exynos3250-mfc" for Exynos3250 SoC. Suggested-by:

Since MFC v7 support was present for both Exynos5420 and Exynos3250 SoC with same compatible string "samsung,mfc-v7". As both SoCs having different hardware properties and having same compatible string for both SoCs doesn't seems to be correct. Add new compatible for Exynos3250 SoC followed by mfc-v7 fallback which will differentiate the node properties for both SoCs which support MFC v7. Reviewed-by:

This allows the device to probe and register its async subdev without a sensor attached. The rationale is that the parent driver might otherwise wait for the subdev to be registered when it should be available (from the fwnode graph endpoint perspective). This is generally not problematic when the MIPI CSI-2 bridge is the only device attached to the parent, but in the case of a CSI controller that can feed from both MIPI CSI-2 and parallel, it would prevent using the parallel sensor due to the parent waiting for the MIPI CSI-2 subdev to register.
