drm/exynos: simplify set_pixfmt() in DECON and FIMD drivers

2017-08-25T05:30:27Z

DRM core already checks the validity of the pixelformat. Signed-off-by: Tobias Jakobi Signed-off-by: Inki Dae

drm/exynos: consistent use of cpp

2017-08-25T05:06:48Z

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.

drm/exynos: kill mode_set_nofb callback

2017-06-01T07:21:35Z

All Exynos CRTCs are fully configured by .enable callback. The only users of mode_set_nofb actually did nothing in their callbacks - they immediately returned because devices were in suspend state - mode_set_nofb is always called on disabled device.

drm/exynos: kill pipe field from drivers contexts

2017-06-01T07:21:34Z

Since possible_crtcs are set by Exynos core helper pipe fields have no raison d'etre. The only place it was used, as a hack, is fimd_clear_channels, to avoid calling drm_crtc_handle_vblank, but DRM core has already other protection mechanism (vblank->enabled), so it could be safely removed.

drm/exynos: set plane possible_crtcs in exynos_plane_init

2017-06-01T07:21:34Z

All Exynos planes are assigned to exactly one CRTC, it allows to simplify initialization by moving setting of possible_crtcs to exynos_plane_init. Signed-off-by: Andrzej Hajda Signed-off-by: Inki Dae

drm/exynos: kill exynos_drm_private::pipe

2017-06-01T07:21:34Z

The field duplicates drm_dev->mode_config.num_crtc. Signed-off-by: Andrzej Hajda Signed-off-by: Inki Dae

drm/exynos: kill exynos_drm_crtc::pipe

2017-06-01T07:21:34Z

Since crtc index is stored in drm_crtc pipe field became redundant. The patch beside removing the field simplifies also exynos_drm_crtc_get_pipe_from_type. Signed-off-by: Andrzej Hajda Signed-off-by: Inki Dae

drm/exynos/fimd: signal frame done interrupt at front porch

2017-03-21T04:17:22Z

VBLANK interrupt should be signalled as soon as scanout ends, front porch is the best moment. Signed-off-by: Andrzej Hajda Signed-off-by: Inki Dae

drm/exynos: move crtc event handling to drivers callbacks

2017-03-21T04:17:21Z

CRTC event is currently send with next vblank, or instantly in case crtc is being disabled. This approach usually works, but in corner cases it can result in premature event generation. Only device driver is able to verify if the event can be sent. This patch is a first step in that direction - it moves event handling to the drivers.

drm/exynos: Remove support for Exynos4415 (SoC not supported anymore)

2017-03-21T04:17:21Z

Support for Exynos4415 is going away because there are no internal nor external users. Since commit 46dcf0ff0de3 ("ARM: dts: exynos: Remove exynos4415.dtsi"), the platform cannot be instantiated so remove also the drivers.
