* [media] V4L2: soc_camera: Renesas R-Car VIN driverVladimir Barinov2013-08-184-0/+1520
| | | | | | | | | | | | | | | Add Renesas R-Car VIN (Video In) V4L2 driver. Based on the patch by Phil Edworthy <phil.edworthy@renesas.com>. [Sergei: removed deprecated IRQF_DISABLED flag, reordered/renamed 'enum chip_id' values, reordered rcar_vin_id_table[] entries, removed senseless parens from to_buf_list() macro, used ALIGN() macro in rcar_vin_setup(), added {} to the *if* statement and used 'bool' values instead of 0/1 where necessary, removed unused macros, done some reformatting and clarified some comments.] Signed-off-by: Vladimir Barinov <vladimir.barinov@cogentembedded.com> Signed-off-by: Sergei Shtylyov <sergei.shtylyov@cogentembedded.com> Signed-off-by: Guennadi Liakhovetski <g.liakhovetski@gmx.de> Signed-off-by: Mauro Carvalho Chehab <m.chehab@samsung.com>

* [media] vsp1: Fix lack of the sink entity registration for enabled linksKatsuya Matsubara2013-08-181-0/+3
| | | | | | | | | | | | | | | | Each source entity maintains a pointer to the counterpart sink entity while an enabled link connects them. It should be managed by the setup_link callback in the media controller framework at runtime. However, enabled links which connect RPFs and WPFs that have an equivalent index number are created during initialization. This registers the pointer to a sink entity from the source entity when an enabled link is created.

* [media] v4l: Renesas R-Car VSP1 driverLaurent Pinchart2013-08-1819-0/+3932
| | | | | | | | | | | | | | | The VSP1 is a video processing engine that includes a blender, scalers, filters and statistics computation. Configurable data path routing logic allows ordering the internal blocks in a flexible way. Due to the configurable nature of the pipeline the driver implements the media controller API and doesn't use the V4L2 mem-to-mem framework, even though the device usually operates in memory to memory mode. Only the read pixel formatters, up/down scalers, write pixel formatters and LCDC interface are supported at this stage.

* [media] media: vb2: Take queue or device lock in mmap-related vb2 ioctl handlersLaurent Pinchart2013-08-181-2/+16
| | | | | | | | | | | | | | | | | The vb2_fop_mmap() and vb2_fop_get_unmapped_area() functions are plug-in implementation of the mmap() and get_unmapped_area() file operations that calls vb2_mmap() and vb2_get_unmapped_area() on the queue associated with the video device. Neither the vb2_fop_mmap/vb2_fop_get_unmapped_area nor the v4l2_mmap/vb2_get_unmapped_area functions in the V4L2 core take any lock, leading to race conditions between mmap/get_unmapped_area and other buffer-related ioctls such as VIDIOC_REQBUFS.

* [media] cx23885[v4]: Fix interrupt storm when enabling IR receiverLuis Alves2013-08-013-2/+41
| | | | | | | | | | | | | | | | | | | | | | Apparently the Flatiron genereates an interrupt after the built-in self test for each of its left and right channels has completed. Apparently Conexant wire-OR'ed the Flatiron's interrupt output with the interrupt output of the CX23885 A/V core. Those interrupts need to be handled, otherwise, they generate an interrrupt request storm. So: - Add flatiron readreg and writereg functions prototypes on a new header file; - Modify the av interrupt handler to cleanup flatiron IRQs if no other interrupt handling happens.

* [media] media: lirc: Allow lirc dev to talk to rc deviceSrinivas Kandagatla2013-07-313-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | The use case is simple, if any rc device has allowed protocols = RC_TYPE_LIRC and map_name = RC_MAP_LIRC set, the driver open will be never called. The reason for this is, all of the key maps except lirc have some KEYS in there map, so during rc_register_device process these keys are matched against the input drivers and open is performed, so for the case of RC_MAP_EMPTY, a vt/keyboard is matched and the driver open is performed. In case of lirc, there is no match and result is that there is no open performed, however the lirc-dev will go ahead and create a /dev/lirc0 node. Now when lircd/mode2 opens this device, no data is available because the driver was never opened. Other case pointed by Sean Young, As rc device gets opened via the input interface. If the input device is never opened (e.g. embedded with no console) then the rc open is never called and lirc will not work either. So that's another case. lirc_dev seems to have no link with actual rc device w.r.t open/close. This patch adds rc_dev pointer to lirc_driver structure for cases like this, so that it can do the open/close of the real driver in accordance to lircd/mode2 open/close. Without this patch its impossible to open a rc device which has RC_TYPE_LIRC ad RC_MAP_LIRC set.

* [media] media: rc: Add rc_open/close and use count to rc_devSrinivas Kandagatla2013-07-312-4/+46
| | | | | | | | | | | | | | | | | | This patch adds user count to rc_dev structure, the reason to add this new member is to allow other code like lirc to open rc device directly. In the existing code, rc device is only opened by input subsystem which works ok if we have any input drivers to match. But in case like lirc where there will be no input driver, rc device will be never opened. Having this user count variable will be usefull to allow rc device to be opened from code other than rc-main. This patch also adds rc_open and rc_close functions for other drivers like lirc to open and close rc devices. This functions safely increment and decrement the user count. Other driver wanting to open rc device should call rc_open and rc_close, rather than directly modifying the rc_dev structure.
