2013-06-28drm/exynos: Clean up logs for DRM_ERROR / DRM_DEBUG_KMSYoungJun Cho
This patch cleans up logs for DRM_ERROR / DRM_DEBUG_KMS to avoid logging duplicated function name because the macros already contain __func__. Signed-off-by: YoungJun Cho <yj44.cho@samsung.com> Signed-off-by: Seung-Woo Kim <sw0312.kim@samsung.com> Signed-off-by: Inki Dae <inki.dae@samsung.com>
2013-06-28drm/exynos: Remove tracking log functionsYoungJun Cho
This patch removes tracking log functions which were used to debug in the early development stage and are not so important as were. So remove them for code clean up.

2013-01-25drm: Convert to devm_ioremap_resource()Thierry Reding
Convert all uses of devm_request_and_ioremap() to the newly introduced devm_ioremap_resource() which provides more consistent error handling. devm_ioremap_resource() provides its own error messages so all explicit error messages can be removed from the failure code paths.

Pull drm update from Dave Airlie: "Exynos and Radeon mostly, with a dma-buf and ttm fix thrown in. It's a bit big but its mostly exynos license fix ups and I'd rather not hold those up since its legally stuff. Radeon has a couple of fixes from dma engine work, TTM is just a locking fix, and dma-buf fix has been hanging around and I finally got a chance to review it." * 'drm-fixes' of git://people.freedesktop.org/~airlied/linux: (30 commits) drm/ttm: fix fence locking in ttm_buffer_object_transfer drm/prime: drop reference on imported dma-buf come from gem drm/radeon: add quirk for d3 delay during switcheroo poweron for apple macbooks drm/exynos: move finish page flip to a common place drm/exynos: fimd: modify condition in fimd resume drm/radeon: fix DMA CS parser for r6xx linear copy packet drm/radeon: split r6xx and r7xx copy_dma functions drm/exynos: Use devm_clk_get in exynos_drm_gsc.c drm/exynos: Remove redundant NULL check in exynos_drm_gsc.c drm/exynos: Remove explicit freeing using devm_* APIs in exynos_drm_gsc.c drm/exynos: Use devm_clk_get in exynos_drm_rotator.c drm/exynos: Remove redundant NULL check in exynos_drm_rotator.c drm/exynos: Remove unnecessary devm_* freeing APIs in exynos_drm_rotator.c drm/exynos: Use devm_clk_get in exynos_drm_fimc.c drm/exynos: Remove redundant NULL check drm/exynos: Remove explicit freeing using devm_* APIs in exynos_drm_fimc.c drm/exynos: Use devm_kzalloc in exynos_drm_ipp.c drm/exynos: fix gem buffer allocation type checking drm/exynos: remove needless parenthesis. drm/exynos: fix incorrect interrupt induced by m2m operation. ...
2013-01-04drm/exynos: Use devm_clk_get in exynos_drm_gsc.cSachin Kamat
This eliminates the need for explicit clk_put and makes the cleanup and exit path code simpler. Signed-off-by: Sachin Kamat <sachin.kamat@linaro.org> Signed-off-by: Inki Dae <inki.dae@samsung.com>
2013-01-04drm/exynos: Remove redundant NULL check in exynos_drm_gsc.cSachin Kamat
devm_request_and_ioremap API checks for NULL. Hence explicit NULL check is not necessary. Saves some code. Signed-off-by: Sachin Kamat <sachin.kamat@linaro.org> Signed-off-by: Inki Dae <inki.dae@samsung.com>
2013-01-04drm/exynos: Remove explicit freeing using devm_* APIs in exynos_drm_gsc.cSachin Kamat
devm_* APIs are device managed and get freed automatically when the device detaches. Thus explicit freeing is not needed. This saves some code. Signed-off-by: Sachin Kamat <sachin.kamat@linaro.org> Signed-off-by: Inki Dae <inki.dae@samsung.com>
2013-01-04drm/exynos: correct some comments to abbreviation.Eunchul Kim
This patch cleanup corrects some comments to abbreviation. We would like to prevent it stands misunderstood. Signed-off-by: Eunchul Kim <chulspro.kim@samsung.com> Signed-off-by: Inki Dae <inki.dae@samsung.com>
2013-01-04drm/exynos: fix build warning.Eunchul Kim
This patch fixes erroneous register read. reall function needs register base address + offset but exynos_drm_gsc module used only offset to read a register. so this patch uses gsc_read function instead of readl. Signed-off-by: Eunchul Kim <chulspro.kim@samsung.com> Signed-off-by: Inki Dae <inki.dae@samsung.com>
2013-01-04drm/exynos: consider both case of vflip and hflip.Eunchul Kim
This patch considers both case of vflip and hflip. If we want that the contents in buffer to be rotated to 180 degree, then we can use h,vflip or 180 degree. Changelog v2: - added EXYNOS_DRM_FLIP_BOTH enum value to avoid build warnning. Signed-off-by: Eunchul Kim <chulspro.kim@samsung.com> Signed-off-by: Inki Dae <inki.dae@samsung.com>
2013-01-04drm/exynos: remove needless error handling to property.Eunchul Kim
This patch removes property error handling. because property couldn't be NULL. Signed-off-by: Eunchul Kim <chulspro.kim@samsung.com> Signed-off-by: Inki Dae <inki.dae@samsung.com>
2013-01-04drm/exynos: change member variable name.Eunchul Kim
This patch change current command name from cmd to c_node. because we are using the member name, 'cmd', for command control ioctl in another structure. so, this patch changes it to c_node to avoid such confusing.

2013-01-03Drivers: gpu: remove __dev* attributes.Greg Kroah-Hartman
CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.

2012-12-14drm/exynos: add gsc ipp driverEunchul Kim
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.
