The cx25821 driver has support for one audio output channel and two video output channels. This is implemented in a very ugly and very evil way through a custom ioctl that passes the filename of a file containing the video data, which is then read by the driver itself using vfs. There are a number of problems with this: 1) it's very ugly and very evil (I can't say that often enough). 2) V4L2 supports video output, so why not use that? 3) it's very buggy, closing the filehandle through which you passed the ioctl will oops the kernel. 4) it's a nasty security leak since this allows you to load any file in the system as a video or audio source, so in theory you can output /etc/passwd to audio or video out and record & decode it on another device. Because of all these issues we no longer register those output video nodes. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

Since rc_unregister_device() frees its argument, the subsequently call to rc_free_device() on the same variable will cause a double free bug.

The default format conversion table mbus_fmt[] in soc_mediabus.c lists "natural" conversions between media-bus and fourcc pixel formats, that are achieved by storing data from the bus in RAM exactly as it arrives, only possibly padding missing high or low bits. Such data acquisition mode cannot change data endianness, therefore two locations with opposite endianness are erroneous. This change might affest the omap1-camera driver, existing configurations should be verified.

By default the VPSS clocks were enabled in capture driver for davinci family which creates duplicates for dm355/dm365/dm644x. This patch adds support to enable the VPSS clocks in VPSS driver, which avoids duplication of code and also adding clock aliases. This patch uses PM runtime API to enable/disable clock, instead of DaVinci clock framework. con_ids for master and slave clocks of vpss is added in pm_domain. This patch cleanups the VPSS clock enabling in the capture driver, and also removes the clock alias in machine file. Along side adds a vpss slave clock for DM365 as mentioned by Sekhar (https://patchwork.kernel.org/patch/1221261/). The Suspend/Resume in dm644x_ccdc.c which enabled/disabled the VPSS clock is now implemented as part of the VPSS driver.

drivers/media/platform/davinci/Kconfig uses selects where it should be using 'depends on'. This results in warnings of the following sort when doing randconfig builds. warning: (VIDEO_DM6446_CCDC && VIDEO_DM355_CCDC && VIDEO_ISIF && VIDEO_DAVINCI_VPBE_DISPLAY) selects VIDEO_VPSS_SYSTEM which has unmet direct dependencies (MEDIA_SUPPORT && V4L_PLATFORM_DRIVERS && ARCH_DAVINCI) The VPIF kconfigs had a strange 'select' and 'depends on' cross linkage which have been fixed as well by removing unneeded VIDEO_DAVINCI_VPIF config symbol. Similarly, remove the unnecessary VIDEO_VPSS_SYSTEM and VIDEO_VPFE_CAPTURE. They don't select any independent functionality and were being used to manage code dependencies which can be handled using makefile. Selecting video modules is now dependent on all ARCH_DAVINCI instead of specific EVMs and SoCs earlier. This should help build coverage. Remove unnecessary 'default y' for some config symbols. While at it, fix the Kconfig help text to make it more readable and fix names of modules created during module build. Rename VIDEO_ISIF to VIDEO_DM365_ISIF as per suggestion from Prabhakar. This patch has only been build tested; I have tried to not break any existing assumptions. I do not have the setup to test video, so any test reports welcome.

Chip id 18 is used by the em2710 and em2820. The current code assumes that if the device is a camera, the chip is an em2710 and an em2820 otherwise. But it turned out that the em2820 is also used in camera devices. "Silvercrest 1.3 MPix" webcams for example are available with both chips. Fortunately both variants are using different generic USD IDs which give us a hint about the used chip.
