2017-08-25drm/exynos: simplify set_pixfmt() in DECON and FIMD driversTobias Jakobi3-16/+3
DRM core already checks the validity of the pixelformat. Signed-off-by: Tobias Jakobi <tjakobi@math.uni-bielefeld.de> Signed-off-by: Inki Dae <inki.dae@samsung.com>
2017-08-25drm/exynos: consistent use of cppTobias Jakobi3-13/+13
A recent commit (272725c7db4da1fd3229d944fc76d2e98e3a144e) has removed the use of 'bits_per_pixel' in DRM. However the corresponding Exynos driver code still uses the ambiguous 'bpp', even though it is now initialized from fb->cpp[0]. Consistenly use 'cpp' in FIMD, DECON7 and DECON5433 drivers.

2017-08-25drm/exynos: mixer: remove src offset from mixer_graph_buffer()Tobias Jakobi1-9/+6
We always translate the dma address such that the offsets of the source image are zero. Hence we can remove manipulation of the MXR_GRAPHIC_SXY(win) register and just zero them once in mixer_win_reset().

2017-08-25drm/exynos: mixer: simplify mixer_graph_buffer()Tobias Jakobi1-4/+1
DRM core already checks in drm_atomic_plane_check() if the pixelformat is valid. Hence we can collapse the default case of the switch statement with the XRGB8888 case. No functional change. Signed-off-by: Tobias Jakobi <tjakobi@math.uni-bielefeld.de> Signed-off-by: Inki Dae <inki.dae@samsung.com>
2017-08-25drm/exynos: mixer: simplify vp_video_buffer()Tobias Jakobi1-20/+6
DRM core already checks in drm_atomic_plane_check() if the pixelformat is valid. Hence we can drop the default case of the switch statement and collapse most of the code. Also rename the two booleans to reflect what true/false actually means, and to avoid mixing CrCb/NV21 descriptions. No functional change.

2017-08-25drm/exynos: mixer: enable NV12MT support for the video planeTobias Jakobi4-1/+35
The video processor supports a tiled version of the NV12 format, known as NV12MT in V4L2 terms. The support was removed in commit 083500baefd5f4c215a5a93aef2492c1aa775828 due to not being a real pixel format, but rather NV12 with a special memory layout. With the introduction of FB modifiers, we can now properly support this format again. Tested with a hacked up modetest from libdrm's test suite on an ODROID-X2 (Exynos4412).

2017-08-25drm/exynos: mixer: fix chroma comment in vp_video_buffer()Tobias Jakobi1-1/+1
The current comment sounds like the division op is done to compensate for some hardware erratum. But the chroma plane having half the height of the luma plane is just the way NV12/NV21 is defined, so clarify this behaviour.

2017-08-25drm/exynos/decon5433: use mode info stored in CRTC to detect i80 modeAndrzej Hajda1-15/+25
Since panel's mode of work is propagated properly from panel to DECON, there is no need to use redundant private device tree property. The only issue with such approach is that check for required interrupts should be postponed until panel communicate its requirements, ie to mode validation phase - mode_valid callback. Signed-off-by: Andrzej Hajda <a.hajda@samsung.com>
2017-08-25drm/exynos: add mode_valid callback to exynos_drmAndrzej Hajda2-0/+15
crtc::mode_valid callback is required to implement proper pipeline validation for command/video modes. Since Exynos uses private framework such callback should be added to it. Signed-off-by: Andrzej Hajda <a.hajda@samsung.com> Signed-off-by: Inki Dae <inki.dae@samsung.com>
2017-08-25drm/exynos/decon5433: refactor irq requesting codeAndrzej Hajda1-24/+30

2017-08-25drm/exynos/mic: use mode info stored in CRTC to detect i80 modeAndrzej Hajda1-40/+4

2017-08-25drm/exynos/dsi: propagate info about command mode from panelAndrzej Hajda2-0/+3
mipi_dsi framework provides information about panel's mode of work. This info should be propagated upstream to configure all elements of the pipeline. As CRTC is the common denominator of the pipeline we can put such info into its structures. Signed-off-by: Andrzej Hajda <a.hajda@samsung.com> Signed-off-by: Inki Dae <inki.dae@samsung.com>
2017-08-25drm/exynos/dsi: refactor panel detection logicAndrzej Hajda1-101/+102
Description of drm_helper_hpd_irq_event clearly states that drivers supporting hotplug events per connector should use different helper - drm_kms_helper_hotplug_event. To achieve it following changes have been performed: - moved down all DSI ops - they require exynos_dsi_disable function to be defined earlier, - simplified exynos_dsi_detect - there is no real detection, it just returns if panel is attached, - DSI attach/detach callbacks attaches/detaches DRM panel and sets connector status and other context fields accordingly, all this is performed under mutex, as these callbacks are asynchronous.

KIQ doesn't really use the GPU scheduler. The base drivers generally use the KIQ ring directly rather than submitting IBs. However, amdgpu_sched_hw_submission (which defaults to 2) limits the number of outstanding fences to 2.

2017-08-23drm/omap: work-around for omap3 display enableTomi Valkeinen1-17/+30
Seems that on omap3 enabling a crtc without any planes causes a sync lost flood. This only happens on the first enable, and after that it works. This looks like an HW issue and it's unclear why this is happening or how to fix it. This started happening after 897145d0c7010b4e07fa9bc674b1dfb9a2c6fff9 ("drm/omapdrm: Move commit_modeset_enables() before commit_planes()") which, as a work-around, changed omapdrm first to do the modeset enable, and plane set only after that.

7d267f068a8b4944d52e8b0ae4c8fcc1c1c5c5ba ("drm/omap: work-around for errata i886") changed how the PLL dividers and multipliers are calculated. While the new way should work fine for all the PLLs, it breaks omap5 PLLs. The issues seen are rather odd: seemed that the output clock rate is half of what we asked. It is unclear what's causing there issues. As a work-around this patch adds a "errata_i886" flag, which is set only for DRA7's PLLs, and the PLL setup is done according to that flag.
