drm/exynos: Add DECON driver

2015-02-11T11:27:08Z

This patch is based on exynos-drm-next branch of Inki Dae's tree at: git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos.git DECON(Display and Enhancement Controller) is the new IP in exynos7 SOC for generating video signals using pixel data. DECON driver can be used to drive 2 different interfaces on Exynos7: DECON-INT(video controller) and DECON-EXT(Mixer for HDMI) The existing FIMD driver code was used as a template to create DECON driver. Only DECON-INT is supported as of now, and DECON-EXT support will be added later. The current version of the driver supports video mode displays. Changelog v2: - Change config name, DRM_EXYNOS_DECON to DRM_EXYNOS7_DECON. Signed-off-by: Akshu Agrawal Signed-off-by: Ajay Kumar Signed-off-by: Inki Dae

drm/exynos: remove DRM_EXYNOS_DMABUF config

2015-02-07T07:38:40Z

The exynos drm driver has DRIVER_PRIME capability, then it's reasonable to support dmabuf as default. Remove DRM_EXYNOS_DMABUF config, it will prevent that user selects the option unnecessarily. Signed-off-by: Joonyoung Shim Reviewed-by: Gustavo Padovan Signed-off-by: Inki Dae

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.
