2014-12-04drm / exynos / PM: Replace CONFIG_PM_RUNTIME with CONFIG_PMRafael J. Wysocki1-1/+1
After commit b2b49ccbdd54 (PM: Kconfig: Set PM_RUNTIME if PM_SLEEP is selected) PM_RUNTIME is always set if PM is set, so #ifdef blocks depending on CONFIG_PM_RUNTIME may now be changed to depend on CONFIG_PM. Replace CONFIG_PM_RUNTIME with CONFIG_PM in 4 files under gpu/drm/exynos/. Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com> Reviewed-by: Jingoo Han <jg1.han@samsung.com>
2014-09-20drm/exynos/ipp: replace work_struct casting with better constructsAndrzej Hajda1-2/+1
Type casting should be avoided if possible. In case of work_struct it can be simply replaced by reference to member field. Signed-off-by: Andrzej Hajda <a.hajda@samsung.com> Reviewed-by: Joonyoung Shim <jy0922.shim@samsung.com> Signed-off-by: Inki Dae <inki.dae@samsung.com>

2013-01-25drm: Convert to devm_ioremap_resource()Thierry Reding1-5/+3
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: Remove redundant NULL check in exynos_drm_gsc.cSachin Kamat1-6/+0

2013-01-04drm/exynos: Remove explicit freeing using devm_* APIs in exynos_drm_gsc.cSachin Kamat1-12/+3

2013-01-04drm/exynos: fix build warning.Eunchul Kim1-1/+1
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.

2013-01-04drm/exynos: consider both case of vflip and hflip.Eunchul Kim1-1/+1
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.

2013-01-03Drivers: gpu: remove __dev* attributes.Greg Kroah-Hartman1-3/+3
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.

2012-12-15drm/exynos: add gsc ipp driverEunchul Kim1-0/+1870
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.
