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:

Philipp Zabel authored
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:

Philipp Zabel authored
It is not correct to calculate decoder capture payload dynamically from the decoded frame width and height reported by the firmware. These tell us what the decoder wrote into the internal framebuffers. The rotator or VDOA always write the full sizeimage when copying the previously decoded frame from the internal framebuffers into the capture queue. Signed-off-by:

It was reported that some cases of interleaved video decoding require using the current destination buffer as a reference. However, this is no longer possible after the move to vb2_find_timestamp because only dequeued and done buffers are considered. Add a helper in our driver that also considers the current destination buffer before resorting to vb2_find_timestamp and use it in MPEG-2. Signed-off-by:

If the operation in rvin_set_channel_routing() is successful the 'ret' variable contains the runtime PM use count for the VIN master device. The intention is not to return the use count to the caller but to return 0 on success else none zero. Fix this by always returning 0 if the operation is successful. Signed-off-by:

French, Nicholas A authored
ivtvfb was previously disabled for x86 PAT-enabled systems by commit 1bf1735b ("x86/mm/pat, drivers/media/ivtv: Use arch_phys_wc_add() and require PAT disabled") as a workaround to abstract MTRR code away from device drivers. The driver is not easily upgradable to the PAT-aware ioremap_wc() API since the firmware hides the address ranges that should be marked write-combined from the driver. However, since a write-combined cache on the framebuffer is only a performance enhancement not a requirement for the framebuffer to function, completely disabling the driver in this configuration is not necessary. Add force_pat module parameter and a corresponding kernel configuration parameter to optionally force initialization on PAT-enabled x86 systems with a warning about the lack of write-combined caching, and document the reasons the driver cannot be easily updated to support wc caching on all systems.
