* [media] V4L: Add driver for S3C24XX/S3C64XX SoC series camera interfaceSylwester Nawrocki2012-11-281-0/+45
| | | | | | | | | | | | | This patch adds V4L2 driver for Samsung S3C24XX/S3C64XX SoC series camera interface. The driver exposes a subdev device node for CAMIF pixel resolution and crop control and two video capture nodes - for the "codec" and "preview" data paths. It has been tested on Mini2440 (s3c2440) and Mini6410 (s3c6410) board with gstreamer and mplayer.

| * [media] adv7604: Replace prim_mode by modeHans Verkuil2012-11-211-11/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Changes the way the primary mode is handled: - Remove it from platform_data since it doesn't belong there. - Add a new mode enum for use with s_routing. - Collapse the two HDMI modes into one HDMI mode: when setting up the timings manually we do not need to select HDMI_COMP mode. That's only needed when selecting a preset. This patch prepares for the next step where we switch to using the presets where available.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds support for DMABUF memory type in videobuf2.

* | [media] rc-core: add separate defines for protocol bitmaps and numbersDavid Härdeman2012-10-273-19/+51
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The RC_TYPE_* defines are currently used both where a single protocol is expected and where a bitmap of protocols is expected. Functions like rc_keydown() and functions which add/remove entries to the keytable want a single protocol. Future userspace APIs would also benefit from numeric protocols (rather than bitmap ones). Keytables are smaller if they can use a small(ish) integer rather than a bitmap. Other functions or struct members (e.g. allowed_protos, enabled_protocols, etc) accept multiple protocols and need a bitmap. Using different types reduces the risk of programmer error. Using a protocol enum whereever possible also makes for a more future-proof user-space API as we don't need to worry about a sufficient number of bits being available (e.g. in structs used for ioctl() calls). The use of both a number and a corresponding bit is dalso one in e.g. the input subsystem as well (see all the references to set/clear bit when changing keytables for example). This patch separate the different usages in preparation for upcoming patches. Where a single protocol is expected, enum rc_type is used; where one or more protocol(s) are expected, something like u64 is used. The patch has been rewritten so that the format of the sysfs "protocols" file is no longer altered (at the loss of some detail). The file itself should probably be deprecated in the future though.

| | | | | | | | | | | | | | | | vpif_display relied on a 1-1 mapping of output and subdev. This is not necessarily the case. Separate the two. So there is a list of subdevs and a list of outputs. Each output refers to a subdev and has routing information. An output does not have to have a subdev. The initial output for each channel is set to the fist output. Currently missing is support for associating multiple subdevs with an output.

| | | | | | | | | | | | | | | | | | | | | | | | | | Initial version of this driver. The full datasheets are available from the Analog Devices website: http://ez.analog.com/docs/DOC-1741 Not all features of the receiver are supported by this driver for various reasons. Most notably: - No CEC support (the CEC API needs a lot more discussion) - No HDCP repeater support (we don't use that either) I'm sure that there are more things missing, but this driver does work well for our hardware. Note that I am using the register addresses instead of register names: the datasheet containing the register descriptions is organized by register address. Using names would make the datasheet lookup very hard. An attempt was made to try and document what is being done when registers are used instead.

* [media] v4l2-common: add CVT and GTF detection functionsHans Verkuil2012-09-131-0/+9
| | | | | | | | | | | | | | These two helper functions detect whether the analog video timings detected by the video receiver match the VESA CVT or GTF standards. They basically do the inverse of the CVT and GTF modeline calculations. This patch also adds a helper function that will determine the aspect ratio based on the provided EDID values. This aspect ratio can be given to the GTF helper function. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

This allows non soc-camera hosts to use soc-camera-aware clients.

* [media] media: rc: Introduce RX51 IR transmitter driverTimo Kokkonen2012-08-131-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | This is the driver for the IR transmitter diode found on the Nokia N900 (also known as RX51) device. The driver is mostly the same as found in the original 2.6.28 based kernel that comes with the device. The following modifications have been made compared to the original driver version: - Adopt to the changes that has happen in the kernel during the past five years, such as the change in the include paths - The OMAP DM-timers require much more care nowadays. The timers need to be enabled and disabled or otherwise many actions fail. Timers must not be freed without first stopping them or otherwise the timer cannot be requested again. The code has been tested with sending IR codes with N900 device running Debian userland. The device receiving the codes was Anysee DVB-C USB receiver.

* [media] dvb: get rid of fe_ioctl_override callbackMauro Carvalho Chehab2012-08-131-3/+1
| | | | | | | | | | | | | | | This callback were meant to allow overriding a FE callback, before its call, but it is not really needed, as the callback can be intercepted after tuner attachment. Worse than that, only DVBv3 calls are intercepted this way, so a DVBv5 application will produce different effects than a DVBv3 one. So, get rid of it.
