Up to now VPE was relying on the colorspace value of struct v4l2_format as an indication to perform color space conversion from YUV to RGB or not. Instead we should used the source/destination fourcc codes as a more reliable indication to perform color space conversion or not. To do so, we rework the csc module to use "struct v4l2_format *" as parameters, and reorganize the coefficients tables in a more logical way. Signed-off-by:

It is often useful to figure out if a pixel_format is either YUV or RGB especially for driver who can perform the pixel encoding conversion. Instead of having each driver implement its own "is_this_yuv/rgb" function based on a restricted set of pixel value, it is better to do this in centralized manner. We therefore add a pixel_enc member to the v4l2_format_info structure to quickly identify the related pixel encoding. And add helper functions to check pixel encoding. Signed-off-by:

For each queue we need to maintain resolutions, pixel format, bytesperline, sizeimage, colorspace, etc. Instead of manually adding more entries in the vpe_q_data struct, it is better to just add a "struct v4l2_format" member and use that to store all needed information. Signed-off-by:

VPE uses VPDMA (built-in dma engine) to transfer data to and from the IP and memory. VPDMA expect 32 bits addresses. To make sure that is always the case set the DMA mask and coherent mask for the device. Signed-off-by:
-
Benoit Parrot authored
Using dma_addr_t as the type to hold address inside of a fix sized descriptor used by the vpdma firmware is prone to fail when the expected width is 32 bits and suddenly when CONFIG_LPAE is enabled the data size is now 64 bits shifted the remaining members of the descriptor in memory which confuses the firmware.

If a subdevice is unregistered and then registered again without the driver being removed and re-probed (which will happen when the media device is removed and re-probed without also removing/re-probing the subdevice), media_device_register_entity() is called with a non-zero entity->num_pads, and then the subdevice's .registered callback calls media_entity_pads_init(). Thus the subdevice's pad objects are added to the media device pad list twice, causing list corruption. One way to fix this would be to create media_entity_pads_destroy(), and call it in the subdevice's .unregistered callback. But calling media_entity_pads_init() in the .registered callbacks was done for legacy reasons and is no longer necessary, so move the call to media_entity_pads_init() into the subdevice's probe functions. This fixes the duplicate pad obejcts in the media device pad list. Signed-off-by:

If the CSI is unregistered and then registered again without the driver being removed and re-probed (which will happen when the media device is removed and re-probed without also removing/re-probing the CSI), the result is the kobject error and backtrace "tried to init an initialized object". This is because the video device is left in an initialized state after being unregistered, thus the video device's underlying kobject is also left in an initialized state when the device is registered again. Fix this by moving imx_media_capture_device_init() and _remove() into csi_registered() and csi_unregistered(). This will create a new un-initialized video device when the CSI is re-registered. Do this for all the subdevices that register a capture device. Reported-by:
