* [media] exynos4-is: Set valid initial format at FIMC-LITESylwester Nawrocki2013-06-28
| | | | | | | | | | Ensure the image resolution and crop rectangle on the FIMC-LITE.n subdevs and fimc-lite.n.capture video nodes is properly configured upon the driver's initialization.

* [media] exynos4-is: Add Exynos5250 SoC support to fimc-lite driverSylwester Nawrocki2013-06-28
| | | | | | | | | | | | | | | | | | 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.

* [media] exynos4-is: Use common exynos_media_pipeline data structureSylwester Nawrocki2013-06-12
| | | | | | | | | This enumeration is now private to exynos4-is and the exynos5 camera subsystem driver may have the subdevs handling designed differently.

* [media] exynos4-is: Media graph/video device locking reworkSylwester Nawrocki2013-06-12
| | | | | | | | | | | | Remove driver private video node reference counters and use entity->use_count instead. This makes the video pipelines power handling more similar to the method used in omap3isp driver. Now the graph mutex is taken always after the video mutex, as it is not possible to ensure apposite order at the all modules.

* [media] exynos4-is: Ensure proper media pipeline state on device closeSylwester Nawrocki2013-04-04
| | | | | | | | | | | | Make sure media_entity_pipeline_stop() is called on video device close in cases where there was VIDIOC_STREAMON ioctl and no VIDIOC_STREAMOFF. This patch fixes media entities stream_count state which could prevent links from being disconnected, due to non-zero stream_count.

* [media] exynos4-is: Allow colorspace conversion at FIMC-LITESylwester Nawrocki2013-04-04
| | | | | | | | | | | | | | | | | | | | | The FIMC-LITE output DMA allows to configure different YUV order than the order at the camera input interface. Thus there is some limited colorspace conversion possible. This patch makes the color format variable be per FIMC-LITE input/output, rather than a global per device. This also fixes incorrect behavior where color format at the FIMC-LITE.N subdev's source pad is modified by VIDIOC_S_FMT ioctl on the related video node. YUV order definitions are corrected so that we use notation: | byte3 | byte2 | byte1 | byte0 -------+-------+-------+-------+------ YCBYCR | CR | Y | CB | Y YCRYCB | CB | Y | CR | Y CBYCRY | Y | CR | Y | CB CRYCBY | Y | CB | Y | CR Signed-off-by: Sylwester Nawrocki <s.nawrocki@samsung.com> Signed-off-by: Kyungmin Park <kyungmin.park@samsung.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
* [media] exynos4-is: Use common driver data for all FIMC-LITE IP instancesSylwester Nawrocki2013-04-04
| | | | | | | | | | | There is no need to use separate variant data structure for each FIMC-LITE IP instance. According to my knowledge there are no differences across them on Exynos4 as well as Exynos5 SoCs. Drop flite_variant data structure and use struct flite_drvdata instead.

* [media] s5p-fimc: Change the driver directory name to exynos4-isSylwester Nawrocki2013-03-31
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.
