phy_power_on() and phy_power_off() already checks for NULL pointer. This patch removes the wrappers exynos_dp_phy_init() and exynos_dp_phy_exit() since the only think they were doing was a check for NULL phy. Signed-off-by:

Instead of blindly ignore the return value of enable_vblank return it to the upper DRM layer for error handling. Suggested-by:

Rename crtc_{widht,height} to crtc_{w,h} and src_{width,height} to src_{w,h} to make it similar to the atomic state names. Signed-off-by: -

Now after the move to use drm_plane_state directly struct drm_plane_state has many unused fields, along with others that weren't used before the plane state change. Thus remove them all. Signed-off-by:

Gustavo Padovan authored
For some fields the use of struct exynos_drm_plane filled with data from the plane state just creates a source of duplicated information and overhead. Here we change the crtc drivers to access the plane state directly simplifying the code by not relying on a exynos internal struct. Signed-off-by:

Gustavo Padovan authored
We already have the plane pointer in before calling .update_plane() or disable_plane() so pass it directly to those calls avoiding a new conversion from zpos to struct exynos_drm_plane. v2: don't remove check for suspended in FIMD (comment by Joonyoung) Signed-off-by:

Get rid of legacy DRM vblank function that are less clear to use. The new ones basically requires only the crtc as parameters. It also clean ups exynos_drm_crtc_finish_pageflip() parameters as a consequence. Signed-off-by:

This is simplest solution about reported problem[1]. It's no problem to clear channel only when iommu is enabled, if we consider that we cannot recognize iommu errors when iommu is disabled and it have been valid until now. But this cannot be nice solution. [1] https://lkml.org/lkml/2015/7/21/404Reported-by:

Already drm_iommu_attach_device checks whether support iommu internally. It should clear channels always regardless iommu support. We didn't know because we can detect the problem when iommu is enabled, so we don't have to use drm_iommu_attach_device_if_possible and then we can remove drm_iommu_attach_device_if_possible and clear_channels function pointer.

The vidi is virtual kms driver and now it is registered earlier than actual hw kms drivers, so it will occupy crtc index 0. Some users assume the condition yet that actual hw kms driver has crtc index 0. It may or may not be matter but let's arrange register order. Signed-off-by:

If CONFIG_ARM_DMA_USE_IOMMU is disable, CONFIG_DRM_EXYNOS_IOMMU also is disable. When CONFIG_DRM_EXYNOS_IOMMU is disable, is_drm_iommu_supported() returns always false, so we can remove to use ifdef CONFIG_ARM_DMA_USE_IOMMU in is_drm_iommu_supported(). Signed-off-by:

Once pm_runtime_set_active() gets called, the kernel assumes that given device has already enabled runtime pm and will call pm_runtime_suspend() without matching pm_runtime_resume(). In case of DRM FIMC IPP driver, this will result in calling clk_disable() without respective call to clk_enable(). This patch removes call to pm_runtime_set_active() to ensure that pm_runtime_suspend/resume calls will match. Signed-off-by:

The bits for rotation are not used as exclusively. So GSC_IN_ROT_270 can not be used for swap detection. The definition of it is same with GSC_IN_ROT_MASK. It is enough to check GSC_IN_ROT_90 bit is set or not to check whether width / height size swapping is needed. Signed-off-by:

Merge tag 'drm-amdkfd-next-fixes-2015-08-05' of git://people.freedesktop.org/~gabbayo/linux into drm-next Two small bug fixes for the code you pulled for 4.3: - Used a SHIFT define instead of a MASK define to check if a bit is turned on when destroying hqd. Luckily, this is in gfx7 interface file with amdgpu, which was used only for bring-up purposes of amdgpu, so no real effect on a running system - Used a logical AND instead of a bitwise AND operator, when initializing sdma virtual memory when using SDMA queues * tag 'drm-amdkfd-next-fixes-2015-08-05' of git://people.freedesktop.org/~gabbayo/linux: drm/amdkfd: fix bug when initializing sdma vm drm/amdgpu: fix bug when amdkfd destroys hqd

Merge branch 'drm-sti-next-atomic-2015-08-11' of http://git.linaro.org/people/benjamin.gaignard/kernel into drm-next This serie of patches fix minor bugs around how driver sub-components are bind and planes z-ordering. The main part is about atomic support: using more atomic helpers allow us to simplify the code (~300 lines removed) and to ahve a better match between drm concepts (planes and crtc) and hardware split.

Name all references to the pipe number (CRTC index) consistently to make it easier to distinguish which is a pipe number and which is a pointer to struct drm_crtc.

The drm_send_vblank_event() function treats negative CRTC indices as meaning that a driver doesn't have proper VBLANK handling. This is the only place where DRM needs negative CRTC indices, so in order to enable subsequent cleanup, remove this special case and replace it by the more obvious check for whether or not VBLANK support was initialized.
