| | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch changes the firmware file names of the FIMC-IS subsystem. It is needed since there are different firmwares used across various SoC series, e.g. Exynos4 and Exynos5. Also the sensor specific "setfile" name is changed, to account for it depends on an image sensor and is also specific to the FIMC-IS and the SoC. This is a change for a driver merged in 3.10.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Add compatible property for the Exynos5250 and enable the frame start and frame end interrupts. These interrupts are needed for the Exynos5 FIMC-IS firmware. The driver enables those interrupt only where available, depending on the 'compatible' property. This can be optimized further, by exposing some API at the subdev driver, so the host driver can enable extra interrupts only for the image processing chains involving FIMC-IS.

| * [media] exynos4-is: Add Exynos5250 SoC support to fimc-lite driverSylwester Nawrocki2013-06-284-14/+121
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds support for the Exynos5250 SoC variant of the FIMC-LITE IP. A 'compatible' string is added for Exynos5250 compatible devices and the capture DMA handling is reworked to use the FLITE_REG_CIFCNTSEQ register, masking output DMA buffer address slots. The frame interrupt is enabled so there are now 2 interrupts per frame. This likely can be optimized in future by using any status registers that allow to figure out what the last and the currently written frame buffer is. It would also be more reliable in cases where there are high interrupt service latencies.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently bridge device drivers register devices for all subdevices synchronously, typically, during their probing. E.g. if an I2C CMOS sensor is attached to a video bridge device, the bridge driver will create an I2C device and wait for the respective I2C driver to probe. This makes linking of devices straight forward, but this approach cannot be used with intrinsically asynchronous and unordered device registration systems like the Flattened Device Tree. To support such systems this patch adds an asynchronous subdevice registration framework to V4L2. To use it respective (e.g. I2C) subdevice drivers must register themselves with the framework. A bridge driver on the other hand must register notification callbacks, that will be called upon various related events.

| * | [media] V4L2: add temporary clock helpersGuennadi Liakhovetski2013-06-212-1/+243
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Typical video devices like camera sensors require an external clock source. Many such devices cannot even access their hardware registers without a running clock. These clock sources should be controlled by their consumers. This should be performed, using the generic clock framework. Unfortunately so far only very few systems have been ported to that framework. This patch adds a set of temporary helpers, mimicking the generic clock API, to V4L2. Platforms, adopting the clock API, should switch to using it. Eventually this temporary API should be removed.

| * | [media] soc-camera: add host clock callbacks to start and stop the master clockGuennadi Liakhovetski2013-06-211-2/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently soc-camera uses a single camera host callback to activate the interface master clock and to configure the interface for a specific client. However, during probing we might not have the information about a client, we just need to activate the clock. Add new camera host driver callbacks to only start and stop the clock without and client-specific configuration.
