Subject: [PATCH v2 0/9] Add Chameleon v3 video support
Date: Wed, 21 Feb 2024 16:02:06 +0000 [thread overview]
Message-ID: <20240221160215.484151-1-panikiel@google.com> (raw)
Google Chameleon v3 is a testing device capable of emulating multiple
DisplayPort monitors, used for testing purposes. It is based on an Arria
10 SoCFPGA. This patchset adds V4L2 drivers for two IP blocks used in
the device's FPGA: the Chameleon v3 framebuffer, and the Intel DisplayPort
RX IP. The former is a video capture device that takes video signal and
writes frames into memory, which can be later processed by userspace.
The latter is a DisplayPort receiver IP from Intel, its datasheet can
be found at:
https://www.intel.com/programmable/technical-pdfs/683273.pdf
The framebuffer driver is a regular v4l2 capture device driver, while
the DP RX driver is a v4l2 subdevice driver. In order to avoid code
duplication, some parts of the DisplayPort code from the DRM subsystem
were put into headers usable by the DP RX driver. Apart from that, the
patchset adds a new callback to the internal v4l2 subdevice API to allow
querying the dv timings of individual video streams of the DP receiver.
v2 changes:
- Add missing includes in dt binding examples
- Add version number to intel,dprx compatible
- Use generic node names in dts
- Add and document IP configuration parameters
- Remove IRQ registers from intel-dprx (they're not a part of the IP)
- Remove no-endpoint property and check for "port" node instead
