drm/exynos: add DSIM driver

2014-04-04T12:24:48Z

The patch adds driver for Exynos DSI master (DSIM). It is a platform driver which is registered as exynos_drm_display sub-driver of exynos_drm framework and implements DRM encoder/connector pair. It is also MIPI-DSI host driver and provides DSI bus for panels. It interacts with its panel(s) using drm_panel framework. Signed-off-by: Andrzej Hajda Signed-off-by: Inki Dae

drm/exynos: restore parallel output interface support

2014-03-23T15:36:40Z

The patch adds parallel output interface to FIMD device driver. It also restores support for panels initialized by boot loader, but without proper kernel driver. Driver uses video interface bindings to find connected panel. It uses drm_panel interface to interact with the panel. Signed-off-by: Andrzej Hajda Reviewed-by: Tomasz Figa Signed-off-by: Inki Dae

drm/exynos: Remove the exynos_drm_connector shim

2014-03-23T15:36:38Z

This path removes the exynos_drm_connector code since it was just passing hooks through display_ops. The individual device drivers are now responsible for implementing drm_connector directly. Signed-off-by: Sean Paul Signed-off-by: Inki Dae

drm/exynos: Move dp driver from video/ to drm/

2014-03-23T15:36:34Z

This patch moves the code from video/ to drm/. This is required the DP driver needs to power on/off in the correct order in relation to fimd. This will also allow the DP driver to participate in drm modeset as well as provide accurate connection detection and edid. Signed-off-by: Sean Paul Signed-off-by: Inki Dae

drm/exynos: Remove exynos_drm_hdmi shim

2014-03-23T15:36:32Z

This patch trims exynos_drm_hdmi out of the driver. The reason it existed in the first place was to make up for the mixture of display/overlay/manager ops being spread across hdmi and mixer. With that code now rationalized, mixer and hdmi map directly to exynos_drm_crtc and exynos_drm_encoder, respectively. Since there is a 1:1 mapping, we no longer need this layer.

drm/exynos: hdmi: remove the i2c drivers and use

2014-03-23T15:36:32Z

The i2c client was previously being passed into the hdmi driver via a dedicated i2c driver, and then a global variable. This patch removes all of that and just uses the device tree to get the i2c_client. This patch also properly references the client so we don't lose it before we're done with it.

drm/exynos: add gsc ipp driver

2012-12-14T17:40:00Z

This patch adds IPP subsystem-based gsc driver for exynos5 series. GSC is stand for General SCaler and supports the following features: - image scaler/rotator/crop/flip/csc and input/output DMA operations. - image rotation and image effect functions. - writeback and display output operations. - M2M operation to crop, scale, rotation and csc. The below is GSC hardware path: Memory------->GSC------>Memory FIMD--------->GSC------>HDMI FIMD--------->GSC------>Memory Memory------->GSC------>FIMD, Mixer This driver is registered to IPP subsystem framework to be used by user side and user can control the GSC hardware through some interfaces of IPP subsystem framework. Changelog v1 ~ v5: - added comments, code fixups and cleanups. Signed-off-by: Eunchul Kim Signed-off-by: Jinyoung Jeon Signed-off-by: Inki Dae Signed-off-by: Kyungmin.park

drm/exynos: add rotator ipp driver

2012-12-14T17:39:41Z

This patch adds IPP subsystem-based rotator driver. And Rotator supports the following features. - Image crop operation support. - Rotate operation support to 90, 180 or 270 degree. - Flip operation support to vertical, horizontal or both. . as limitaions, the pixel format to source buffer should be same as the one to destination buffer and no scaler. This driver is registered to IPP subsystem framework to be used by user side and user can control the Rotator hardware through some interfaces of IPP subsystem framework. Changelog v6: - fix build warning. Changelog v1 ~ v5: - added comments, code fixups and cleanups.

drm/exynos: add fimc ipp driver

2012-12-14T17:38:53Z

FIMC is stand for Fully Interfactive Mobile Camera and supports image scaler/rotator/crop/flip/csc and input/output DMA operations and also supports writeback and display output operations. This driver is registered to IPP subsystem framework to be used by user side and user can control the FIMC hardware through some interfaces of IPP subsystem framework.

drm/exynos: add ipp subsystem

2012-12-14T17:29:08Z

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.
