2014-04-06[media] rc-core: remove generic scancode filterDavid Härdeman1-0/+2
The generic scancode filtering has questionable value and makes it impossible to determine from userspace if there is an actual scancode hw filter present or not. So revert the generic parts. Based on a patch from James Hogan <james.hogan@imgtec.com>, but this version also makes sure that only the valid sysfs files are created in the first place.

git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media Pull media updates from Mauro Carvalho Chehab: "The main set of series of patches for media subsystem, including: - document RC sysfs class - added an API to setup scancode to allow waking up systems using the Remote Controller - add API for SDR devices. Drivers are still on staging - some API improvements for getting EDID data from media inputs/outputs - new DVB frontend driver for drx-j (ATSC) - one driver (it913x/it9137) got removed, in favor of an improvement on another driver (af9035) - added a skeleton V4L2 PCI driver at documentation - added a dual flash driver (lm3646) - added a new IR driver (img-ir) - added an IR scancode decoder for the Sharp protocol - some improvements at the usbtv driver, to allow its core to be reused. - added a new SDR driver (rtl2832u_sdr) - added a new tuner driver (msi001) - several improvements at em28xx driver to fix PM support, device removal and to split the V4L2 specific bits into a separate sub-driver - one driver got converted to videobuf2 (s2255drv) - the e4000 tuner driver now follows an improved binding model - some fixes at V4L2 compat32 code - several fixes and enhancements at videobuf2 code - some cleanups at V4L2 API documentation - usual driver enhancements, new board additions and misc fixups" [ NOTE! This merge effective drops commit 4329b93b283c ("of: Reduce indentation in of_graph_get_next_endpoint"). The of_graph_get_next_endpoint() function was moved and renamed by commit fd9fdb78a9bf ("[media] of: move graph helpers from drivers/media/v4l2-core to drivers/of"). It was originally called v4l2_of_get_next_endpoint() and lived in the file drivers/media/v4l2-core/v4l2-of.c. In that original location, it was then fixed to support empty port nodes by commit b9db140c1e46 ("[media] v4l: of: Support empty port nodes"), and that commit clashes badly with the dropped "Reduce intendation" commit.

2014-03-11[media] vb2: only call start_streaming if sufficient buffers are queuedHans Verkuil1-4/+10
In commit 02f142ecd24aaf891324ffba8527284c1731b561 support was added to start_streaming to return -ENOBUFS if insufficient buffers were queued for the DMA engine to start. The vb2 core would attempt calling start_streaming again if another buffer would be queued up. Later analysis uncovered problems with the queue management if start_streaming would return an error: the buffers are enqueued to the driver before the start_streaming op is called, so after an error they are never returned to the vb2 core. The solution for this is to let the driver return them to the vb2 core in case of an error while starting the DMA engine. However, in the case of -ENOBUFS that would be weird: it is not a real error, it just says that more buffers are needed. Requiring start_streaming to give them back only to have them requeued again the next time the application calls QBUF is inefficient. This patch changes this mechanism: it adds a 'min_buffers_needed' field to vb2_queue that drivers can set with the minimum number of buffers required to start the DMA engine. The start_streaming op is only called if enough buffers are queued. The -ENOBUFS handling has been dropped in favor of this new method. Drivers are expected to return buffers back to vb2 core with state QUEUED if start_streaming would return an error. The vb2 core checks for this and produces a warning if that didn't happen and it will forcefully reclaim such buffers to ensure that the internal vb2 core state remains consistent and all buffer-related resources have been correctly freed and all op calls have been balanced. __reqbufs() has been updated to check that at least min_buffers_needed buffers could be allocated. If fewer buffers were allocated then __reqbufs will free what was allocated and return -ENOMEM. Based on a suggestion from Pawel Osciak. __create_bufs() doesn't do that check, since the use of __create_bufs assumes some advance scenario where the user might want more control. Instead streamon will check if enough buffers were allocated to prevent streaming with fewer than the minimum required number of buffers.

Before calling buf_finish set the buffer state to PREPARED, which is the correct state. That way the states DONE and ERROR will only be seen in buf_finish if streaming is in progress. Since buf_finish can now be called from non-streaming state we need to adapt the handful of drivers that actually need to know this.

They are renamed to of_graph_get_next_endpoint, of_graph_get_remote_port, and of_graph_get_remote_port_parent, respectively.

This applies to HDMI-map register 0x69. So far we have been using HPA manual mode. This way we had control of HPA which could be set after EDID had been programmed. Using a Mac Mini with mini-displayport to DVI-D converter as source caused the adv7842 to lock up and fail to detect any further signals.

2014-01-07[media] vb2: retry start_streaming in case of insufficient buffersHans Verkuil1-4/+11
If start_streaming returns -ENOBUFS, then it will be retried the next time a buffer is queued. This means applications no longer need to know how many buffers need to be queued before STREAMON can be called. This is particularly useful for output stream I/O. If a DMA engine needs at least X buffers before it can start streaming, then for applications to get a buffer out as soon as possible they need to know the minimum number of buffers to queue before STREAMON can be called. You can't just try STREAMON after every buffer since on failure STREAMON will dequeue all your buffers. (Is that a bug or a feature? Frankly, I'm not sure). This patch simplifies applications substantially: they can just call STREAMON at the beginning and then start queuing buffers and the DMA engine will kick in automagically once enough buffers are available. This also fixes using write() to stream video: the fileio implementation calls streamon without having any queued buffers, which will fail today for any driver that requires a minimum number of buffers.

Both the PAL and NTSC standards are interlaced where a frame consist of two fields. Total number of lines in a frame in both systems are an odd number so the two fields will have different length. In the 625 line standard ("PAL") the odd field of the frame is transmitted first, while in the 525 standard ("NTSC") the even field is transmitted first. This adds the possibility to change output config between the fields and standards.

2013-12-20[media] omap24xx/tcm825x: move to staging for future removalHans Verkuil1-305/+0
The omap24xx driver and the tcm825x sensor driver are the only two remaining drivers to still use the old deprecated v4l2-int-device API. Nobody maintains these drivers anymore. But unfortunately the v4l2-int-device API is used by out-of-tree drivers (MXC platform). This is a very bad situation since as long as this deprecated API stays in the kernel there is no reason for those out-of-tree drivers to convert. This patch moves v4l2-int-device and the two drivers that depend on it to staging in preparation for their removal. If someone would be interested in getting these drivers to work, then start with this since it's not very far from the state where they used to work: <URL:http://vihersipuli.retiisi.org.uk/cgi-bin/gitweb.cgi?p=~sailus/linux-omap/.git;a=summary> The branch is n800-cam. Porting to up-to-date APIs can then be done. David might have done some work in that area, so check with him first.

2013-12-18[media] v4l: atmel-isi: Should clear bits before set the hardware registerJosh Wu1-0/+2
In the ISI driver it reads the config register to get original value, then set the correct FRATE_DIV and YCC_SWAP_MODE directly. This will cause some bits overlap. So we need to clear these bits first, then set correct value. This patch fix it.
