Add I2C/V4L2 subdev driver for Siliconfile NOON010PC30 CIF camera. The driver implements basic functionality, i.e. CIF/QCIF/QQCIF resolution and color format selection, automatic/manual color balance control. Other functions like cropping, rotation/flip, exposure etc. can be easily implemented if needed. Reviewed-by:

This patch fixes the value of FIFO_CTRL in MSCTRL. Main-scaler has the value to specify a basis FIFO control of input DMA. The description of FIFO_CTRL has been changed as below. 0 = FIFO Empty (Next burst transaction is possible when FIFO is empty) 1 = FIFO Full (Next burst transaction is possible except Full FIFO) Value '1' is recommended to enhance the FIMC operation performance.

This patch adds callback functions, stop_streaming and job_abort, to abort or finish any DMA in progress. stop_streaming is called by videobuf2 framework and job_abort is called by m2m framework. ST_M2M_PEND state is added to discard the next job. Reviewed-by:

Horizontal and vertical scaling range are according to the following equations. If (SRC_Width >= 64 x DST_Width) { Exit(-1); /* Out of Horizontal scale range} If (SRC_Height >= 64 x DST_Height) { Exit(-1); /* Out of Vertical scale range} fimc_check_scaler_ratio() is used to check if horizontal and vertical scale range are valid or not. To use fimc_check_scaler_ratio, source and destination format should be set by VIDIOC_S_FMT. And in case of scaling up, it doesn't have to check the scale range. Reviewed-by: -

The main scaler has four SFRs for main scaler ratio depending on FIMC version. FIMC 4.x has only two SFRs and FIMC 5.x has four SFRs for main scaler. Those are MainHorRatio, MainHorRatio_ext, MainVerRatio and MainverRatio_ext. The FIMC 5.x has 15 bit resolution for scaling ratio as below. {MainHorRatio,MainHorRatio_ext} = {[14:6],[5:0]}. {MainVerRatio,MainVerRatio_ext} = {[14:6],[5:0]}. MainHorRatio = CISCCTRL[24:16], MainHorRatio_ext = CIEXTEN[15:10] MainVerRatio = CISCCTRL[8:0], MainVerRatio_ext = CIEXTEN[5:0] This patch supports FIMC 4.x and FIMC 5.x using platform_device_id::driver_data.

Some color formats are mismatched in s5p-fimc driver. CIOCTRL[1:0], order422_out, should be set 2b'00 not 2b'11 to use V4L2_PIX_FMT_YUYV. Because in V4L2 standard V4L2_PIX_FMT_YUYV means "start + 0: Y'00 Cb00 Y'01 Cr00 Y'02 Cb01 Y'03 Cr01". According to datasheet 2b'00 is right value for V4L2_PIX_FMT_YUYV. Signed-off-by: -

Add a generic file io (read and write) emulator for videobuf2. It uses MMAP memory type buffers and generic vb2 calls: req_bufs, qbuf and dqbuf. Video date is being copied from mmap buffers to userspace with standard copy_to_user() function. To add support for file io the driver needs to provide an additional callback - read_setup or write_setup. It should provide the default number of buffers used by emulator and flags. With these flags one can detemine the style of read() or write() emulation. By default 'streaming' style is used. With VB2_FILEIO_READ_ONCE flag one can select 'one shot' mode for read() emulator. With VB2_FILEIO_WRITE_IMMEDIATE flag one can select immediate conversion of write calls to qbuf for write() emulator, so the vb2 will not wait until each buffer is filled completely before queueing it to the driver.

Videobuf2 is a Video for Linux 2 API-compatible driver framework for multimedia devices. It acts as an intermediate layer between userspace applications and device drivers. It also provides low-level, modular memory management functions for drivers. Videobuf2 eases driver development, reduces drivers' code size and aids in proper and consistent implementation of V4L2 API in drivers. Videobuf2 memory management backend is fully modular. This allows custom memory management routines for devices and platforms with non-standard memory management requirements to be plugged in, without changing the high-level buffer management functions and API. The framework provides: - implementations of streaming I/O V4L2 ioctls and file operations - high-level video buffer, video queue and state management functions - video buffer memory allocation and management Signed-off-by:

Multi-planar API is as a backwards-compatible extension of the V4L2 API, which allows video buffers to consist of one or more planes. Planes are separate memory buffers; each has its own mapping, backed by usually separate physical memory buffers. Many different uses for the multi-planar API are possible, examples include: - embedded devices requiring video components to be placed in physically separate buffers, e.g. for Samsung S3C/S5P SoC series' video codec, Y and interleaved Cb/Cr components reside in buffers in different memory banks; - applications may receive (or choose to store) video data of one video buffer in separate memory buffers; such data would have to be temporarily copied together into one buffer before passing it to a V4L2 device; - applications or drivers may want to pass metadata related to a buffer and it may not be possible to place it in the same buffer, together with video data.

This patch is adding support for Technisat's new USB2.0 DVB-S/S2 receiver device. The development was sponsored by Technisat. The Green led is toggle depending on the frontend-state. The Red LED is turned on all the time. The MAC address reading from the EEPROM along with the LRC-method to check whether its valid. Support for the IR-receiver of the Technisat USB2 box. The keys of small, black remote-control are built-in, repeated key behaviour are simulated. The i2c-mutex of the dvb-usb-structure is used as a general mutex for USB requests, as there are 3 threads racing for atomic requests consisting of multiple usb-requests. A module option is there which disables the toggling of LEDs by the driver on certain triggers. Useful when being used in a "dark" environment.
