media: em28xx: fix a regression with HVR-950

2018-08-03T05:47:55+00:00

[ Upstream commit 509f89652f83e834b3ef7a083e2eeac812b055f0 ] Commit be7fd3c3a8c5 ("media: em28xx: Hauppauge DualHD second tuner functionality") removed the logic with sets the alternate for the DVB device. Without setting the right alternate, the device won't be able to submit URBs, and userspace fails with -EMSGSIZE: ERROR DMX_SET_PES_FILTER failed (PID = 0x2000): 90 Message too long Tested with Hauppauge HVR-950 model A1C0.

media: em28xx: Fix DualHD broken second tuner

2018-08-03T05:47:53+00:00

[ Upstream commit 01affb000e00cfa0a9e9954476ef50962eb8b168 ] The use of a hard coded i2c address breaks the creation of the second tuner in DualHD 01595 models. The issue is compounded by lack of any error message stating that a driver failed initialization. Use addr, which contains the correct address for each tuner.

commit f620d1d7afc7db57ab59f35000752840c91f67e7 upstream. media: uvcvideo: Support UVC 1.5 video probe & commit controls The length of UVC 1.5 video control is 48, and it is 34 for UVC 1.1. Change it to 48 for UVC 1.5 device, and the UVC 1.5 device can be recognized. More changes to the driver are needed for full UVC 1.5 compatibility. However, at least the UVC 1.5 Realtek RTS5847/RTS5852 cameras have been reported to work well.

media: uvcvideo: Prevent setting unavailable flags

2018-06-25T23:51:30+00:00

commit 0dc68cabdb626e33d02561529e6a4c681b72a784 upstream. The addition of an extra operation to use the GET_INFO command overwrites all existing flags from the uvc_ctrls table. This includes setting all controls as supporting GET_MIN, GET_MAX, GET_RES, and GET_DEF regardless of whether they do or not. Move the initialisation of these control capabilities directly to the uvc_ctrl_fill_xu_info() call where they were originally located in that use case, and ensure that the new functionality in uvc_ctrl_get_flags() will only set flags based on their reported capability from the GET_INFO call.

MAINTAINERS & files: Canonize the e-mails I use at files

2018-05-04T10:21:06+00:00

From now on, I'll start using my @kernel.org as my development e-mail. As such, let's remove the entries that point to the old mchehab@s-opensource.com at MAINTAINERS file. For the files written with a copyright with mchehab@s-opensource, let's keep Samsung on their names, using mchehab+samsung@kernel.org, in order to keep pointing to my employer, with sponsors the work. For the files written before I join Samsung (on July, 4 2013), let's just use mchehab@kernel.org. For bug reports, we can simply point to just kernel.org, as this will reach my mchehab+samsung inbox anyway.

media: cx231xx: Increase USB bridge bandwidth

2018-04-04T10:27:28+00:00

The cx231xx USB bridge has issue streaming QAM256 DVB-C channels. QAM64 channels were fine, but QAM256 channels produced corrupted transport streams. cx231xx alt mode 4 does not provide enough bandwidth to acommodate QAM256 DVB-C channels, most likely DVB-T2 channels would break up as well. Alt mode 5 increases bridge bandwidth to 90Mbps, and fixes QAM256 DVB-C streaming. Signed-off-by: Brad Love Signed-off-by: Mauro Carvalho Chehab
