There are several comments all over the place, which uses a wrong singular form of jiffies. Replace 'jiffie' by 'jiffy'. No functional change.

media: cec: extron-da-hd-4k-plus: add the Extron DA HD 4K Plus CEC driver

2024-09-05T18:13:41+00:00

Add support for the Extron DA HD 4K Plus series of 4K HDMI Distrubution Amplifiers (aka HDMI Splitters). These devices support CEC and this driver adds support for the CEC protocol for both the input and all outputs (2, 4 or 6 outputs, depending on the model). It also exports the EDID from the outputs and allows reading and setting the EDID of the input. Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: uapi: videodev2: Add V4L2_META_FMT_RK_ISP1_EXT_PARAMS

2024-08-12T10:36:32+00:00

The rkisp1 driver stores ISP configuration parameters in the fixed rkisp1_params_cfg structure. As the members of the structure are part of the userspace API, the structure layout is immutable and cannot be extended further. Introducing new parameters or modifying the existing ones would change the buffer layout and cause breakages in existing applications. The allow for future extensions to the ISP parameters, introduce a new extensible parameters format, with a new format 4CC. Document usage of the new format in the rkisp1 admin guide.

Documentation: media: vivid.rst: update TODO list

2024-08-09T05:56:38+00:00

The vivid driver supports media controller support for quite a long time now, so drop that from the list. Since commit 4c4dacb052d4 ("media: vivid: loopback based on 'Connected To' controls") making EDID changes causes correct signaling to happen, but what is still missing is the 100 ms delay required before signaling that there is an HPD. Modify this TODO item accordingly. Signed-off-by: Hans Verkuil

media: em28xx: Add support for MyGica UTV3

2024-06-29T10:20:05+00:00

The MyGica UTV3 Analog USB2.0 TV Box is a USB video capture card that has analog TV, composite video, and FM radio inputs, an IR remote, and provides audio only as Line Out, but not over USB. Mine is prepared for an FM tuner, but not equipped with one. Support for FM radio is therefore missing. The device contains: - Empia EM2860 USB bridge - Philips SAA7113 video decoder - NXP TDA9801T demodulator - Tena TNF931D-DFDR1 tuner - ST HCF4052 demux, switches input audio to Line Out Signed-off-by: Nils Rothaug Signed-off-by: Sean Young Signed-off-by: Hans Verkuil
