* [media] gscaler: Add new driver for generic scalerSungchun Kang2012-09-152-0/+597
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds support for G-Scaler (Generic Scaler) device which is a new device for scaling and color space conversion on EXYNOS5 SoCs. This patch adds the code for register definitions and register operations. This device supports the followings as key feature. 1) Input image format - RGB888/565, YUV422 1P/2P, YUV420 2P/3P, TILE 2) Output image format - RGB888/565, YUV422 1P/2P, YUV420 2P/3P, YUV444 3) Input rotation - 0/90/180/270 degree, X/Y Flip 4) Scale ratio - 1/16 scale down to 8 scale up 5) CSC - RGB to YUV / YUV to RGB 6) Size - 2048 x 2048 for tile or rotation - 4800 x 3344 other case Signed-off-by: Hynwoong Kim <khw0178.kim@samsung.com> Signed-off-by: Sungchun Kang <sungchun.kang@samsung.com> Signed-off-by: Shaik Ameer Basha <shaik.ameer@samsung.com> Reviewed-by: Sylwester Nawrocki <s.nawrocki@samsung.com> Signed-off-by: Sylwester Nawrocki <s.nawrocki@samsung.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

| | | | | | | | | | | | 1) We always re-create the input-urb on resume, so we must also always destroy it on suspend to avoid leaking it 2) If we're going to do an init_transfer, then that will destroy the urb before starting the stream (nop if there is none), and (re-)create it once the stream is started.

* [media] gspca: Don't set gspca_dev->dev to NULL before stop0Hans de Goede2012-09-138-22/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | In commit a3d6e8cc0e6ddc8b3cfdeb3c979f07ed1aa528b3 gspca_dev->dev is set to NULL on disconnect, before calling stop0. The plan was to get rid of gspca_dev->present and instead simply check for gspca_dev->dev everywhere where we were checking for present. This should be race free since all users of gspca_dev->dev hold the usb_lock, or so I thought. But I was wrong, drivers which use a work-queue + synchronous bulk transfers to get the video data don't hold the usb_lock while doing so, their stop0 callbacks stop the workqueue, so they won't be using gspca_dev->dev anymore after the stop0 call, but they might be dereferincing it before, so we should not set gspca_dev->dev to NULL on disconnect before calling stop0. This also means that the workqueue functions in these drivers cannot use gspca_dev->dev to check if they need to stop because of disconnection, so we will need to keep gspca_dev->present around, and set that to 0 on disconnect, before calling stop0. Unfortunately as part of the plan to remove gspca_dev->present, these workqueues where already moved over to checking for gspca_dev->dev instead of gspca_dev->present as part of commit 254902b01d2acc6aced99ec17caa4c6cd890cdea, so this patch also reverts those parts of that commit.

* [media] ad9389b: driver for the Analog Devices AD9389B video encoderHans Verkuil2012-09-133-0/+1340
| | | | | | | | | | | | | | | | | | | | | | | | | | 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.
