Takes the ov9281 part only from the Rockchip's patch. Change-Id: I30e833baf2c1bb07d6d87ddb3b00759ab45a90e4 Signed-off-by: Zefa Chen <[email protected]>
…and hal3 Adds the ov9281 parts of the Rockchip patch adding enum_frame_interval to a large number of drivers. Change-Id: I03344cd6cf278dd7c18fce8e97479089ef185a5c Signed-off-by: Zefa Chen <[email protected]>

I have fixups for general API usage, so fixups on style can go in there too. |

More fixups required - I ran v4l2-compliance against it and got 8 failures. Colorspace mainly, and some streaming ioctl ones. |
…om code The Rockchip driver was based on a 4.4 kernel, and had several custom Rockchip parts. Update to 5.4 kernel APIs, with the relevant controls required by libcamera, and remove custom Rockchip parts. Signed-off-by: Dave Stevenson <[email protected]>
Vision Components have made an OV9281 module which blocks reading back the majority of registers to comply with NDAs, and in doing so doesn't allow auto-increment register reading as used when reading the chip ID. Use two reads and manually combine the results. Signed-off-by: Dave Stevenson <[email protected]>
Adds an overlay for the OV9281 mono imaging sensor using 2 CSI-2 data lanes. Signed-off-by: Dave Stevenson <[email protected]>
Adds the driver for use by the dtoverlay. Signed-off-by: Dave Stevenson <[email protected]>

Updated. Hopefully thaat is all the changes required for libcamera to be happy too. |
|
LGTM |

I've not seen anything wrong with it. |

Pulls in a driver for OV9281 from Rockchip's kernel tree, and then fixes it up to match mainline.
As it stands the first 3 commits won't build, but also the module isn't in the defconfig. Patch 4 fixes up the driver. The patches could be squashed but I really wanted to leave the history of where it came from.
Just noted that I've missed adding it to the defconfig, but also the patch for the Vision Components board doesn't work as the ID comes back as 0x72FF, so I'm reworking that.
