media: uapi: add MEDIA_BUS_FMT_METADATA_FIXED media bus format.

2023-05-17T09:13:09+00:00

[ Upstream commit 6ad253cc3436269fc6bcff03d704c672f368da0a ] MEDIA_BUS_FMT_METADATA_FIXED should be used when the same driver handles both sides of the link and the bus format is a fixed metadata format that is not configurable from userspace. The width and height will be set to 0 for this format.

media: videodev2.h: RGB BT2020 and HSV are always full range

2020-11-05T10:08:40+00:00

[ Upstream commit b305dfe2e93434b12d438434461b709641f62af4 ] The default RGB quantization range for BT.2020 is full range (just as for all the other RGB pixel encodings), not limited range. Update the V4L2_MAP_QUANTIZATION_DEFAULT macro and documentation accordingly. Also mention that HSV is always full range and cannot be limited range. When RGB BT2020 was introduced in V4L2 it was not clear whether it should be limited or full range, but full range is the right (and consistent) choice.

media: replace ADOBERGB by OPRGB

2018-11-13T19:08:54+00:00

commit db0340182444612bcadb98bdec22f651aa42266c upstream. The CTA-861 standards have been updated to refer to opRGB instead of AdobeRGB. The official standard is in fact named opRGB, so switch to that. The two old defines referring to ADOBERGB in the public API are put under #ifndef __KERNEL__ and a comment mentions that they are deprecated.

media: cec: add new tx/rx status bits to detect aborts/timeouts

2018-11-13T19:08:53+00:00

commit 7ec2b3b941a666a942859684281b5f6460a0c234 upstream. If the HDMI cable is disconnected or the CEC adapter is manually unconfigured, then all pending transmits and wait-for-replies are aborted. Signal this with new status bits (CEC_RX/TX_STATUS_ABORTED). If due to (usually) a driver bug a transmit never ends (i.e. the transmit_done was never called by the driver), then when this times out the message is marked with CEC_TX_STATUS_TIMEOUT. This should not happen and is an indication of a driver bug. Without a separate status bit for this it was impossible to detect this from userspace. The 'transmit timed out' kernel message is now a warning, so this should be more prominent in the kernel log as well.

The new format will be called V4L2_PIX_FMT_Y10P. It is similar to the V4L2_PIX_FMT_SBGGR10P family formats but V4L2_PIX_FMT_Y10P is a grayscale format. Signed-off-by: Todor Tomov Acked-by: Sakari Ailus Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

These formats are compressed 14-bit raw bayer formats with four different pixel orders. They are similar to 10-bit variants. The formats added by this patch are V4L2_PIX_FMT_SBGGR14P V4L2_PIX_FMT_SGBRG14P V4L2_PIX_FMT_SGRBG14P V4L2_PIX_FMT_SRGGB14P Signed-off-by: Sakari Ailus Acked-by: Hans Verkuil Signed-off-by: Todor Tomov Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab
