Call video_set_drvdata to register the driver private pointer when not already done. Where applicable, the local list of mappings is completely removed when it becomes unused.

This makes debug, informational and error messages easier to understand for end users.

Remove those unneeded assignments.

test for error conditions that can't happen anymore with the current v4l-dvb core, - store the value in a driver private field that isn't used anymore, - check the video device type where video_device::vfl_type should be used, or - create the name of a kernel thread that should get a stable name. Remove or fix those use cases.

This is based on version v1.2 of the RFC titled "V4L - Support for video timings at the input/output interface" Following new ioctls are added:- - VIDIOC_ENUM_DV_PRESETS - VIDIOC_S_DV_PRESET - VIDIOC_G_DV_PRESET - VIDIOC_QUERY_DV_PRESET - VIDIOC_S_DV_TIMINGS - VIDIOC_G_DV_TIMINGS Please refer to the RFC for the details. This code was tested using vpfe capture driver on TI's DM365. Following is the test configuration used :- Blu-Ray HD DVD source -> TVP7002 -> DM365 (VPFE) ->DDR A draft version of the TVP7002 driver (currently being reviewed in the mailing list) was used that supports V4L2_DV_1080I60 & V4L2_DV_720P60 presets. A loopback video capture application was used for testing these APIs. This calls following IOCTLS :- - verify the new v4l2_input capabilities flag added - Enumerate available presets using VIDIOC_ENUM_DV_PRESETS - Set one of the supported preset using VIDIOC_S_DV_PRESET - Get current preset using VIDIOC_G_DV_PRESET - Detect current preset using VIDIOC_QUERY_DV_PRESET - Using stub functions in tvp7002, verify VIDIOC_S_DV_TIMINGS and VIDIOC_G_DV_TIMINGS ioctls are received at the sub device. - Tested on 64bit platform by Hans Verkuil Signed-off-by: Muralidharan Karicheri Signed-off-by: Hans Verkuil Reviewed-by: Randy Dunlap Signed-off-by: Mauro Carvalho Chehab --- drivers/media/video/v4l2-compat-ioctl32.c | 6 + drivers/media/video/v4l2-ioctl.c | 147 ++++++++++++++++++++++ include/linux/videodev2.h | 116 ++++++++++++++++- include/media/v4l2-ioctl.h | 15 +++ include/media/v4l2-subdev.h | 21 ++++ 5 files changed, 303 insertions(+), 2 deletions(-) diff --git a/drivers/media/video/v4l2-compat-ioctl32.c b/drivers/media/video/v4l2-compat-ioctl32.c index 997975d5e02..c4150bd2633 100644 --- a/drivers/media/video/v4l2-compat-ioctl32.c +++ b/drivers/media/video/v4l2-compat-ioctl32.c @@ -1077,6 +1077,12 @@ long v4l2_compat_ioctl32(struct file *file, unsigned int cmd, unsigned long arg) case VIDIOC_DBG_G_REGISTER: case VIDIOC_DBG_G_CHIP_IDENT: case VIDIOC_S_HW_FREQ_SEEK: + case VIDIOC_ENUM_DV_PRESETS: + case VIDIOC_S_DV_PRESET: + case VIDIOC_G_DV_PRESET: + case VIDIOC_QUERY_DV_PRESET: + case VIDIOC_S_DV_TIMINGS: + case VIDIOC_G_DV_TIMINGS: ret = do_video_ioctl(file, cmd, arg); break; diff --git a/drivers/media/video/v4l2-ioctl.c b/drivers/media/video/v4l2-ioctl.c index 30cc3347ae5..4b11257c318 100644 --- a/drivers/media/video/v4l2-ioctl.c +++ b/drivers/media/video/v4l2-ioctl.c @@ -284,6 +284,12 @@ static const char *v4l2_ioctls[] = { [_IOC_NR(VIDIOC_DBG_G_CHIP_IDENT)] = "VIDIOC_DBG_G_CHIP_IDENT", [_IOC_NR(VIDIOC_S_HW_FREQ_SEEK)] = "VIDIOC_S_HW_FREQ_SEEK", #endif + [_IOC_NR(VIDIOC_ENUM_DV_PRESETS)] = "VIDIOC_ENUM_DV_PRESETS", + [_IOC_NR(VIDIOC_S_DV_PRESET)] = "VIDIOC_S_DV_PRESET", + [_IOC_NR(VIDIOC_G_DV_PRESET)] = "VIDIOC_G_DV_PRESET", + [_IOC_NR(VIDIOC_QUERY_DV_PRESET)] = "VIDIOC_QUERY_DV_PRESET", + [_IOC_NR(VIDIOC_S_DV_TIMINGS)] = "VIDIOC_S_DV_TIMINGS", + [_IOC_NR(VIDIOC_G_DV_TIMINGS)] = "VIDIOC_G_DV_TIMINGS", }; #define V4L2_IOCTLS ARRAY_SIZE(v4l2_ioctls) @@ -1135,6 +1141,19 @@ static long __video_do_ioctl(struct file *file, { struct v4l2_input *p = arg; + /* + * We set the flags for CAP_PRESETS, CAP_CUSTOM_TIMINGS & + * CAP_STD here based on ioctl handler provided by the + * driver.

Instead of just getting 6 bits, improve the routine to get 11 bits. This means that the complete RC5 table for Hauppauge Grey IR can be used with this device. Unfortunately, it seems that this IR receiver is not capable of getting the full 14 (or 13 bits) from the RC5 protocol. At lest now, with the new code, it is possible to replace this IR table by another RC5 table.

As such, the better is to have the input_register_device()/input_unregister_device() inside the ir register/unregister functions. Also, solves a naming problem with V4L ir_input_init() function, that were, in fact, registering a device. While here, do a few cleanups at budget-ci IR logic.

Data is being transferred over these busses in various formats, which only loosely correspond to fourcc codes, describing how video data is stored in RAM. This is not a one-to-one correspondence, therefore we cannot use fourcc codes to configure subdevice output data formats. This patch adds codes for several such on-the-bus formats and an API, similar to the familiar .s_fmt(), .g_fmt(), .try_fmt(), .enum_fmt() API for configuring those codes. After all users of the old API in struct v4l2_subdev_video_ops are converted, it will be removed. Also add helper routines to support generic pass-through mode for the soc-camera framework. create mode 100644 drivers/media/video/soc_mediabus.c create mode 100644 include/media/soc_mediabus.h create mode 100644 include/media/v4l2-mediabus.h Signed-off-by: Guennadi Liakhovetski Acked-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab --- drivers/media/video/Makefile | 2 +- drivers/media/video/soc_mediabus.c | 157 +++++++++++++++++++++++++++++ include/media/soc_mediabus.h | 65 ++++++++++++ include/media/v4l2-mediabus.h | 61 +++++++++++ include/media/v4l2-subdev.h | 18 +++- 5 files changed, 301 insertions(+), 2 deletions(-) create mode 100644 drivers/media/video/soc_mediabus.c create mode 100644 include/media/soc_mediabus.h create mode 100644 include/media/v4l2-mediabus.h diff --git a/drivers/media/video/Makefile b/drivers/media/video/Makefile index 7a2dcc34111..e7bc8daae06 100644 --- a/drivers/media/video/Makefile +++ b/drivers/media/video/Makefile @@ -149,7 +149,7 @@ obj-$(CONFIG_VIDEO_VIVI) += vivi.o obj-$(CONFIG_VIDEO_CX23885) += cx23885/ obj-$(CONFIG_VIDEO_OMAP2) += omap2cam.o -obj-$(CONFIG_SOC_CAMERA) += soc_camera.o +obj-$(CONFIG_SOC_CAMERA) += soc_camera.o soc_mediabus.o obj-$(CONFIG_SOC_CAMERA_PLATFORM) += soc_camera_platform.o # soc-camera host drivers have to be linked after camera drivers obj-$(CONFIG_VIDEO_MX1) += mx1_camera.o diff --git a/drivers/media/video/soc_mediabus.c b/drivers/media/video/soc_mediabus.c new file mode 100644 index 00000000000..f8d5c87dc2a --- /dev/null +++ b/drivers/media/video/soc_mediabus.c @@ -0,0 +1,157 @@ +/* + * soc-camera media bus helper routines + * + * Copyright (C) 2009, Guennadi Liakhovetski + * + * This program is free software;

We disable non-working size ranges until, maybe, someone finds out how to properly set them up. Also add cropping support, an auto white balance control, platform data to specify master clock frequency and polarity of the IOCTL pin. create mode 100644 include/media/rj54n1cb0c.h Signed-off-by: Guennadi Liakhovetski Signed-off-by: Mauro Carvalho Chehab --- arch/sh/boards/mach-kfr2r09/setup.c | 13 +- drivers/media/video/rj54n1cb0c.c | 275 +++++++++++++++++++++++----- include/media/rj54n1cb0c.h | 19 ++ 3 files changed, 260 insertions(+), 47 deletions(-) create mode 100644 include/media/rj54n1cb0c.h diff --git a/arch/sh/boards/mach-kfr2r09/setup.c b/arch/sh/boards/mach-kfr2r09/setup.c index 87438d6603d..9038d768a52 100644 --- a/arch/sh/boards/mach-kfr2r09/setup.c +++ b/arch/sh/boards/mach-kfr2r09/setup.c @@ -19,6 +19,7 @@ #include #include #include +#include #include #include #include
