Since the FIMC-IS firmware communicates with an image sensor directly through the ISP I2C bus controllers data streaming cannot be simply enabled from left to right or disabled from right to left along the processing pipeline. Thus a subdev index to call s_stream() on is looked up from a table, rather than doing the op call based on increasing/decreasing indexes. Signed-off-by:

In configurations where FIMC-LITE is used to capture image signal from an external sensor only we need to ensure one of FIMC devices is in active power state and the "fimc" gate clock is enabled. Otherwise the CAMCLK clock output signal will be masked off preventing an external sensor's operation. This affect processing pipelines like: - sensor -> FIMC-LITE -> memory - sensor -> MIPI-CSIS -> FIMC-LITE -> memory Signed-off-by:

A second sink pad is added to each FIMC.N subdev that will be used to link it to the FIMC-IS-ISP subdev. Only V4L2_MBUS_FMT_YUV10_1X30 format is supported at this pad (FIMC_SD_PAD_SINK_FIFO). The routine checking for mismatch in the image formats at sides of the links is updated to account for the fact FIMC.X subdevs now have sink pads at the pad indexes 0, 1 and source pad at pad index 2. If link to FIMC.X pad 1 is activated we switch FIMC input data bus type to the ISP Writeback. Only a single active link to FIMC.X pad 0 or 1 will be allowed at any time. Signed-off-by:

We cannot assume that the passed entity the fimc_pipeline_prepare() function is supposed to start the media graph traversal from will always have its sink pad at pad index 0. Find the starting media entity's sink pad by iterating over its all pads and checking the pad flags. This ensures proper handling of FIMC, FIMC-LITE and FIMC-IS-ISP subdevs that have more than one sink and one source pad. Signed-off-by:

Before the camera ports can be used the pinmux needs to be configured properly. This patch adds a function to set the camera ports pinctrl to a default state within the media driver's probe(). The camera port(s) are then configured for the video bus operation. Signed-off-by:

The sensor (I2C and/or SPI client) devices are instantiated by their corresponding control bus drivers. Since the I2C client's master clock is often provided by a video bus receiver (host interface) or other than I2C/SPI controller device, the drivers of those client devices are not accessing hardware in their driver's probe() callback. Instead, after enabling clock, the host driver calls back into a sub-device when it wants to activate them. This pattern is used by some in-tree drivers and this patch also uses it for DT case. This patch is intended as a first step for adding device tree support to the S5P/Exynos SoC camera drivers. The second one is adding support for asynchronous sub-devices registration and clock control from sub-device driver level. The bindings shall not change when asynchronous probing support is added.

This patch adds changes required for the main camera media device driver corresponding to the top level 'camera' device node. The drivers of devices corresponding to child nodes of the 'camera' node are looked up and and registered as sub-devices to the top level driver. The main driver's probing is deferred if any of the sub-device drivers is not yet initialized and ready. Signed-off-by:

This patch adds device tree support for FIMC driver on S5PV210 and Exynos4 SoCs. The FIMC IP block's features and quirks encoded statically in the driver are now parsed from the device tree. Once all relevant platforms are converted to device tree based booting the FIMC variant data structures will all be removed from the driver. Signed-off-by:

It doesn't matter whether we start from the sensor of from the video node entity. Remove use of pipeline->subdevs array where possible, so we can partly drop dependency on struct fimc_pipeline in the fimc-lite module, which is also used by the exynos5-is driver. Also make sure we revert any media entity pipeline operations when vb2_streamon() function fails. Signed-off-by:

This patch adds a document describing common OF bindings for video capture, output and video processing devices. It is curently mainly focused on video capture devices, with data busses defined by standards such as ITU-R BT.656 or MIPI-CSI2. It also documents a method of describing data links between devices.

Loading the cypress firmware is not dvb specific and should be common functionality. Move the source to media/common and make it a standalone module. As a result we can remove the dependency on dvb-usb in go7007, which has nothing to do with dvb. Signed-off-by:

On powerpc the maximum size for the ioctl argument is 8191, and it was 8192. However, the 64x64 array of threshold values is more than is actually needed in practice for PAL and NTSC formats. A 45x45 array will do just fine. So change the size accordingly to fix this problem. Signed-off-by:

Patch protects from setting up frequency on device to incorrect value moving clamp_t check inside amradio_set_freq. With this patch we can call amradio_set_freq() with out of range frequency from any place. Also put comment that sometimes radio->curfreq is set to out of range value in vidioc_s_hw_freq_seek().

This sensor is used by the "SpeedLink Vicious And Devine Laplace webcam" and others. It supports resolutions up to 1600x1200 (at 7-8 fps), but for resolutions higher than 640x480, further driver changes will be necessary, such as sensor output resolution switching (including further configuration changes), bridge xclk adjustment and disabling of 16 bit (12 bit) output formats at high resolutions. Image quality should also needs to be improved. Signed-off-by:

The Windows driver also probes at least two further i2c addresses (0x22 >> 1 and 0x66 >> 1). I've got some hints that they are very likely used by Samsung and Kodak sensors, which are known to be used in Empia devices, too. We havn't seen any devices using these sensors yet and don't know how to probe them properly, so leave a comment. Signed-off-by:

OmniVision sensors are used as well in Empiatech based cameras such as the "SpeedLink Vicious And Devine Laplace" webcam (EM2765 + Omnivision OV2640). With this patch applied, OminiVision sensors with 8 bit address and register width are detected (recent models have a 16 bit address width and use different client addresses). The most commonly used sensors (including the ones listed by Empiatech) are detected properly, although there is no support for them yet. Signed-off-by:
