The "Codec Interface" chapter is poorly named since codecs are just one use-case of the Memory-to-Memory Interface. Rename it and clean up the text a bit. Signed-off-by:

The zero timestamp is really valid so fix that mistake by dropping the code which checks for zero timestamp. Reviewed-by:

By historical reasons we defined firmware memory size to be 6MB even that the firmware size for all supported Venus versions is 5MBs. Correct that by compare the required firmware size returned from mdt loader and the one provided by DT reserved memory region. We proceed further if the required firmware size is smaller than provided by DT memory region. Reviewed-by:

This provides more power saving when the sensor is off. While at that, do the delay on power/clock enable even if the sensor driver itself doesn't control the GPIOs. This is required for the OLPC XO-1 platform, that lacks the proper power/reset properties in its DT, but needs the delay after the sensor is clocked up. Signed-off-by:

The commit 71862f63 ("media: ov7670: Add the ov7670_s_power function") added a power control routing. However, it was not good enough to use as a s_power() callback: it merely flipped on the power GPIOs without restoring the register settings. Fix this now and register an actual power callback.

Some imx platforms do not have fwnode connections to all CSI input ports, and should not be treated as an error. This includes the imx6q SabreAuto, which has no connections to ipu1_csi1 and ipu2_csi0. Return -ENOTCONN in imx_csi_parse_endpoint() so that v4l2-fwnode endpoint parsing will not treat an unconnected CSI input port as an error.

Implement the vidioc_(un)subscribe_event operations. Imx will allow subscribing to the imx-specific frame interval error events, events from subdevices (V4L2_EVENT_SOURCE_CHANGE), and control events. Signed-off-by:
-
Steve Longerbeam authored
In order to receive events generated by subdevices on the video capture nodes, those events need to be forwarded to the subdevice's list of reachable video capture devices. Note this will queue the event to a video device even if there is no actual _enabled_ media path from the sub-device to the video device. So a future improvement is to skip the video device if there is no enabled path to it from the sub-device. The entity->pipe pointer can't be used for this check because in imx-media a sub-device can be a member to more than one streaming pipeline at a time. Signed-off-by:

The CSI, PRP ENC, and PRP VF subdevices shouldn't have to care about IDMAC line start address alignment. With compose rectangle support in the capture driver, they don't have to anymore. If the direct CSI -> IC path is enabled, the CSI output width must still be aligned to 8 pixels (IC burst length). Signed-off-by:

Allowing to compose captured images into larger memory buffers will let us lift alignment restrictions on CSI crop width. For now all compose rectangles are identical to the complete frame width / height. This will be changed in the next patches. Signed-off-by:
