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 video interface, 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 video interface 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. This patchset depends on changes merged into the linux-media tree at: git://linuxtv.org/hverkuil/media_tree.git tags/br-v6.10d Here is the output of `v4l2-compliance -s` run on a Chameleon v3 for

and max dv timing caps - Set pixelclock to htotal * vtotal * 24Hz (we can't detect the actual value) - Remove enum_framesizes - Use v4l2_match_dv_timings() - Add V4L2_CID_DV_RX_POWER_PRESENT control - Use V4L2_DV_BT_CEA_1920X1080P60 as default timing - Use vb2_video_unregister_device() - Move subdev pad initialization to probe - Change subdev entity function to MEDIA_ENT_F_DV_DECODER - Drop dprx 'port' property and always use 'ports' instead - Remove legacy-format property and use multiple compats - Cleanup notifier only in non-fallback mode - Cleanup subdev entity using media_entity_cleanup() - Increase HPD pulse length to 500ms (see comment in dprx_set_edid()) - Pull HPD low before updating EDID - Add a DisplayPort media bus type - Move receiver properties to port endpoint (data-lanes, link-frequencies) 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 Paweł Anikiel (10): media: Add Chameleon

``` > > v3 changes: > - Send v4l2-subdev API changes as a separate patchset > - Drop chameleonv3/ directory > - Change capture device name from "framebuffer" to "video interface" > - Set sensible min and max dv timing caps > - Set pixelclock to htotal * vtotal * 24Hz (we can't detect the actual value) > - Remove enum_framesizes > - Use v4l2_match_dv_timings() > - Add V4L2_CID_DV_RX_POWER_PRESENT control > - Use V4L2_DV_BT_CEA_1920X1080P60 as default timing > - Use vb2_video_unregister_device() > - Move subdev pad initialization to probe > - Change subdev entity function to MEDIA_ENT_F_DV_DECODER > - Drop dprx 'port' property and always use 'ports' instead > - Remove legacy-format property and use multiple compats > - Cleanup notifier only in non-fallback mode > - Cleanup subdev entity using media_entity_cleanup() > - Increase HPD pulse length to 500ms (see comment in dprx_set_edid()) > - Pull HPD low before updating EDID > - Add a DisplayPort media bus type > - Move receiver properties to port endpoint (data-lanes, link-frequencies) > > 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 > > Paweł Anikiel (10): > media: Add Chameleon v3 video interface driver > drm/dp_mst: Move DRM-independent structures to separate header > lib: Move DisplayPort CRC functions to common
