2013-03-31[media] s5p-fimc: Change the driver directory name to exynos4-isSylwester Nawrocki1-1025/+0
The s5p-fimc directory now contains drivers for multiple IP blocks found in multiple Samsung application processors. This includes FIMC (CAMIF), MIPI CSIS and FIMC LITE. FIMC-IS (Imaging Subsystem) driver is going to be put into same directory. Hence we rename it to exynos4-is as s5p-fimc was only relevant for early version of this driver, when it only supported FIMC IP block. The imaging subsystem drivers for Exynos4 SoC series and S5PV210 will be included in drivers/media/platform/exynos4-is directory, with some modules shared with exynos5 series, while the rest of exynos5 specific modules will find their home in drivers/media/platform/exynos5-is.

2013-02-06[media] s5p-csis: Fix clock handling on error path in probe()Sylwester Nawrocki1-3/+4
Move e_clkput label after the clk_disable() call so a not acquired clock is not attempted to be disabled.

2013-01-03Drivers: media: remove __dev* attributes.Greg Kroah-Hartman1-3/+3
CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, __devinitdata, __devinitconst, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.

2012-10-05[media] s5p-fimc: Add support for V4L2_PIX_FMT_S5C_UYVY_JPG fourccSylwester Nawrocki1-2/+6
The V4L2_PIX_FMT_S5C_YUYV_JPG image formats consists of 2 planes, the first containing interleaved JPEG/YUYV data and the second containing meta data describing the interleaving method. The image data is transferred with MIPI-CSI "User Defined Byte-Based Data 1" type and is captured to memory by FIMC DMA engine. The meta data is transferred using MIPI-CSI2 "Embedded 8-bit non Image Data" and it is captured in the MIPI-CSI slave device and copied to the bridge provided buffer. To make sure the size of allocated buffers is correct for the subdevs configuration when VIDIOC_STREAMON ioctl is invoked, an additional check is added at the video pipeline validation function. Flag FMT_FLAGS_COMPRESSED indicates the buffer size must be retrieved from a sensor subdev.

2012-10-05[media] s5p-csis: Add support for non-image data packets captureSylwester Nawrocki1-1/+43
MIPI-CSI has internal memory mapped buffers for the frame embedded (non-image) data. There are two buffers, for even and odd frames which need to be saved after an interrupt is raised. The packet data buffers size is 4 KiB and there is no status register in the hardware where the actual non-image data size can be read from. Hence the driver copies whole packet data buffer into a buffer provided by the FIMC driver. This will form a separate plane in the user buffer. When FIMC DMA engine is stopped by the driver due the to user space not keeping up with buffer de-queuing the MIPI-CSIS will still run, however it must discard data which is not captured by FIMC. Which frames are actually capture by MIPI-CSIS is determined by means of the s_tx_buffer subdev callback. When it is not called after a single embedded data frame has been captured and copied and before next embedded data frame interrupt occurrs, subsequent embedded data frames will be dropped.
