As the driver maintaines separate buffer lists per each video device which are beyond control of v4l2/vb2 framework, those lists should be properly handled and cleared once the buffers are no longer available.

2014-11-27exynos3: fimc-is: Add support for FIMC IS on Exynos3250Beata Michalska21-922/+3462
The changes introduced provide support for FIMC-IS subsystem avalilable on Exynos3250. They cover the differences in both: the hardware itself as well as the subtle discrepancies between the firmwares controlling the FIMC IS on both SoCs. Regarding the above mentioned firmware variations: the initial driver has been extended with a simplified interface handling those variations thus living the core driver independent of the actual firmware version. Missing code paths have been added to cover handling some of the most probable failures/errors.

2014-11-27[media] Add driver for exynos5 FIMC-IS subsystemArun Kumar K22-0/+7243
This driver is for the FIMC-IS IP available in Samsung Exynos5 SoC onwards. exynos5-fimc-is: Add common driver header files This patch adds all the common header files used by the fimc-is driver. It includes the commands for interfacing with the firmware and error codes from IS firmware, metadata and command parameter definitions. exynos5-fimc-is: Add register definition and context header This patch adds the register definition file for the fimc-is driver and also the header file containing the main context for the driver. exynos5-fimc-is: Add isp subdev fimc-is driver takes video data input from the ISP video node which is added in this patch. This node accepts Bayer input buffers which is given from the IS sensors. exynos5-fimc-is: Add scaler subdev FIMC-IS has two hardware scalers named as scaler-codec and scaler-preview. This patch adds the common code handling the video nodes and subdevs of both the scalers. exynos5-fimc-is: Add sensor interface Some sensors to be used with fimc-is are exclusively controlled by the fimc-is firmware. This minimal sensor driver provides the required info for the firmware to configure the sensors sitting on I2C bus. exynos5-fimc-is: Add the hardware pipeline control This patch adds the crucial hardware pipeline control for the fimc-is driver. All the subdev nodes will call this pipeline interfaces to reach the hardware. Responsibilities of this module involves configuring and maintaining the hardware pipeline involving multiple sub-ips like ISP, DRC, Scalers, ODC, 3DNR, FD etc. exynos5-fimc-is: Add the hardware interface module The hardware interface module finally sends the commands to the FIMC-IS firmware and runs the interrupt handler for getting the responses.

2014-11-27exynos5-is: Add media device driver for exynos5 SoCs camera subsystemShaik Ameer Basha2-0/+1336
This patch adds a top level media device driver for the Exynos5 SoC series camera subsystem. The driver currently supports processing pipelines involving following IP blocks: * MIPI-CSIS MIPI CSI-2 bus front-end to the FIMC-LITE, image sensors with MIPI CSI-2 bus should be linked with FIMC-LITE through this sub-device. * FIMC-LITE Supports capture interface from device (Sensor, MIPI-CSIS) to memory. Supports interconnection (through internal data FIFO links) between devices like MIPI-CSIS and FIMC-IS. * FIMC-IS Camera ISP with multiple image processing and peripheral devices like I2C or SPI bus controllers. The G-Scaler IP is not yet supported. The media device creates two kinds of pipelines for connecting the above mentioned IP blocks. The pipeline0 contains Sensor, MIPI-CSIS and FIMC-LITE devices and allows to capture image data from external sensor to memory. Pipeline1 uses FIMC-IS components for image processing operations on the captured raw image data and provides scaled YUV image data at its output.

However this clock is not defined yet on any platform, so before adding it to all Exynos platform, better rename it to "sclk_mfc" to match the scheme used for all other special clocks on Exynos platform.

2014-11-18[media] s5p-mfc: Fix selective sclk_mfc initJacek Anaszewski1-0/+24
fc906b6d "Remove special clock usage in driver" removed initialization of MFC special clock, arguing that there's no need to do it explicitly, since it's one of MFC gate clock's dependencies and gets enabled along with it. However, there's no promise of keeping this hierarchy across Exynos SoC releases, therefore this approach fails to provide a stable, portable solution. Out of all MFC versions, only v6 doesn't use special clock at all. For other versions log a message only in case clk_get fails, as not all the devices with the same MFC version require initializing the clock explicitly.

2014-11-18[media] s5p-jpeg: Fix build break when CONFIG_OF is undefinedJacek Anaszewski1-10/+8
This patch fixes build break occurring when there is no support for Device Tree turned on in the kernel configuration. In such case only the driver variant for S5PC210 SoC will be available.

2014-11-18[media] s5p-jpeg: Prevent JPEG 4:2:0 > YUV 4:2:0 decompressionJacek Anaszewski1-3/+22
Prevent decompression of a JPEG 4:2:0 with odd width to the YUV 4:2:0 compliant formats for Exynos4x12 SoCs and adjust capture format to RGB565 in such a case. This is required because the configuration would produce a raw image with broken luma component.

2014-11-18[media] s5p-jpeg: Fix sysmmu page faultJacek Anaszewski1-3/+43
This patch fixes jpeg sysmmu page fault on Exynos4x12 SoCs. During encoding Exynos4x12 SoCs access wider memory area than it results from Image_x and Image_y values written to the JPEG_IMAGE_SIZE register. In order to avoid sysmmu page fault apply proper output buffer size alignment.
