* [media] s5p-tv: remove obsolete driverHans Verkuil2016-08-24
| | | | | | | | | | | The s5p-tv driver has been replaced by the exynos drm driver for quite a long time now. Remove this driver to avoid having duplicate drivers, of which this one is considered dead code by Samsung.

* drm/exynos: Use VIDEO_SAMSUNG_S5P_G2D=n as G2D Kconfig dependencyJavier Martinez Canillas2016-04-29
| | | | | | | | | | | | | | | | | Commit 254d4d111ee1 ("drm/exynos: Add dependency for G2D in Kconfig") made the DRM_EXYNOS_G2D symbol to only be selectable if the s5p-g2d V4L2 driver is not enabled, since both use the same HW IP block. But added the dependency as depends on !VIDEO_SAMSUNG_S5P_G2D which isn't correct since Kconfig expressions are not boolean but tristate. So it will only evaluate to 'n' if VIDEO_SAMSUNG_S5P_G2D=y but it will evaluate to m if VIDEO_SAMSUNG_S5P_G2D=m. This means that both the V4L2 and DRM drivers can be enabled if the former is enabled as a module, which is not what we want.

* drm: bridge: analogix/dp: split exynos dp driver to bridge directoryYakir Yang2016-04-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Split the dp core driver from exynos directory to bridge directory, and rename the core driver to analogix_dp_*, rename the platform code to exynos_dp. Beside the new analogix_dp driver would export six hooks. "analogix_dp_bind()" and "analogix_dp_unbind()" "analogix_dp_suspned()" and "analogix_dp_resume()" "analogix_dp_detect()" and "analogix_dp_get_modes()" The bind/unbind symbols is used for analogix platform driver to connect with analogix_dp core driver. And the detect/get_modes is used for analogix platform driver to init the connector. They reason why connector need register in helper driver is rockchip drm haven't implement the atomic API, but Exynos drm have implement it, so there would need two different connector helper functions, that's why we leave the connector register in helper driver.

I moved DRM_PTN3460 earlier in Kconfig, next to the I2C helper module section, so that the user has a chance to select it before moving to the Exynos-specific section.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds OF initialization support for the FIMC driver. The binding documentation can be found at Documentation/devicetree/ bindings/media/samsung-fimc.txt. The syscon regmap interface is used to serialize access to the shared CAMBLK registers from within the V4L2 FIMC-IS and the DRM FIMC drivers. The DRM driver uses this interface for setting up the FIFO data link between FIMD and FIMC IP blocks, while the V4L2 one for setting up a data link between the camera ISP and FIMC for camera capture. The CAMBLK registers are not accessed any more through a statically mapped IO. Synchronized access to these registers is required for simultaneous operation of the camera ISP and the DRM IPP on Exynos4x12. The driver data and driver_ids static data structures are removed since Exynos4 is going to be a dt-only platform and there is currently no board file in mainline that defines platform data for the FIMC IPP, i.e. uses it.

* drm/exynos: fimd and ipp are broken on multiplatformArnd Bergmann2013-01-25
| | | | | | | | | | | | | | | | | | While the exynos DRM support in principle can work on multiplatform, the FIMD and IPP sections of it both include the plat/map-base.h header file, which is not available on multiplatform. Rather than disabling the entire driver, we can just conditionally build these two parts. Without this patch, building allyesconfig results in: drivers/gpu/drm/exynos/exynos_drm_fimc.c:19:27: fatal error: plat/map-base.h: No such file or directory drivers/gpu/drm/exynos/exynos_drm_ipp.c:20:27: fatal error: plat/map-base.h: No such file or directory Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Inki Dae <inki.dae@samsung.com> Signed-off-by: Kyungmin Park <kyungmin.park@samsung.com>

* drm/exynos: add ipp subsystemEunchul Kim2012-12-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds Image Post Processing(IPP) support for exynos drm driver. IPP supports image scaler/rotator and input/output DMA operations using IPP subsystem framework to control FIMC, Rotator and GSC hardware and supports some user interfaces for user side. And each IPP-based drivers support Memory to Memory operations with various converting. And in case of FIMC hardware, it also supports Writeback and Display output operations through local path. Features: - Memory to Memory operation support. - Various pixel formats support. - Image scaling support. - Color Space Conversion support. - Image crop operation support. - Rotate operation support to 90, 180 or 270 degree. - Flip operation support to vertical, horizontal or both. - Writeback operation support to display blended image of FIMD fifo on screen A summary to IPP Subsystem operations: First of all, user should get property capabilities from IPP subsystem and set these properties to hardware registers for desired operations. The properties could be pixel format, position, rotation degree and flip operation. And next, user should set source and destination buffer data using DRM_EXYNOS_IPP_QUEUE_BUF ioctl command with gem handles to source and destinition buffers. And next, user can control user-desired hardware with desired operations such as play, stop, pause and resume controls. And finally, user can aware of dma operation completion and also get destination buffer that it contains user-desried result through dequeue command. IOCTL commands: - DRM_EXYNOS_IPP_GET_PROPERTY . get ipp driver capabilitis and id. - DRM_EXYNOS_IPP_SET_PROPERTY . set format, position, rotation, flip to source and destination buffers - DRM_EXYNOS_IPP_QUEUE_BUF . enqueue/dequeue buffer and make event list. - DRM_EXYNOS_IPP_CMD_CTRL . play/stop/pause/resume control. Event: - DRM_EXYNOS_IPP_EVENT . a event to notify dma operation completion to user side. Basic control flow: Open -> Get properties -> User choose desired IPP sub driver(FIMC, Rotator or GSCALER) -> Set Property -> Create gem handle -> Enqueue to source and destination buffers -> Command control(Play) -> Event is notified to User -> User gets destinition buffer complated -> (Enqueue to source and destination buffers -> Event is notified to User) * N -> Queue/Dequeue to source and destination buffers -> Command control(Stop) -> Free gem handle -> Close Changelog v1 ~ v5: - added comments, code fixups and cleanups.

* drm/exynos: add iommu support for exynos drm frameworkInki Dae2012-11-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Changelog v4: - fix condition to drm_iommu_detach_device funtion. Changelog v3: - add dma_parms->max_segment_size setting of drm_device->dev. - use devm_kzalloc instead of kzalloc. Changelog v2: - fix iommu attach condition. . check archdata.dma_ops of drm device instead of subdrv device's one. - code clean to exynos_drm_iommu.c file. . remove '#ifdef CONFIG_ARM_DMA_USE_IOMMU' from exynos_drm_iommu.c and add it to driver/gpu/drm/exynos/Kconfig. Changelog v1: This patch adds iommu support for exynos drm framework with dma mapping api. In this patch, we used dma mapping api to allocate physical memory and maps it with iommu table and removed some existing codes and added new some codes for iommu support. GEM allocation requires one device object to use dma mapping api so this patch uses one iommu mapping for all sub drivers. In other words, all sub drivers have same iommu mapping.
