2017-01-18drm: mediatek: use crtc helper drm_crtc_from_index()Shawn Guo
Use drm_crtc_from_index() to find drm_crtc for given index, so that we do not need to maintain a pointer array in struct mtk_drm_private.

2016-08-11drm/mediatek: set mt8173 dithering functionBibby Hsieh
Some panels only accept bpc (bit per color) 6-bit. But, the default bpc in mt8173 display data path is 8-bit. If we didn't enable dithering function to convert bpc, display cannot show the smooth grayscale image. In mt8173, the dithering function in OD (OverDrive) and GAMMA module, we have to config them with connector->display_mode.bpc when CRTC initial. 1. Clear the default value at *_DITHER_5 and *_DITHER_7 register. 2. Calculate the LSB_ERR_SHIFT bits and ADD_LSHIFT bits two values. i.e. Input bpc of OD is 10 bits, we assume the bpc of panel is 6-bit, so, we need to set 4-bit to LSB_ERR_SHIFT and ADD_LSHIFT bits respectively. 3. Then, set the OD or GAMMA to dithering mode depends on path-1 or path-2. Signed-off-by: Bibby Hsieh <bibby.hsieh@mediatek.com> Signed-off-by: Philipp Zabel <p.zabel@pengutronix.de>

Add gamma set function to correct brightness values. It applies arbitrary mapping curve to compensate the incorrect transfer function of the panel. Signed-off-by: Bibby Hsieh <bibby.hsieh@mediatek.com> Signed-off-by: Philipp Zabel <p.zabel@pengutronix.de>

Use the core destroy_state helpers to destroy core state to ensure we don't leak if/when more fields get added later.

2016-08-08drm/mediatek: Remove mtk_drm_planeDaniel Kurtz
Now that mtk_drm_plane just contains its base struct drm_plane, we can just remove it and use struct drm_plane everywhere.

2016-08-08drm/mediatek: plane: Remove plane zpos/indexDaniel Kurtz
It is not actually useful to a mtk plane to know its zpos/index, so just remove this field. This let's completely remove struct mtk_drm_plane in a follow up patch.

2016-05-17drm: Drop crtc argument from __drm_atomic_helper_crtc_destroy_stateDaniel Vetter
It's unused, and really this helper should only look at the state structure and nothing else. v2: Rebase on top of rockchip changes v3: Drop unrelated hunk, spotted by Laurent. v4: Rebase onto mtk driver merge.

2016-05-06drm/mediatek: Add DRM Driver for Mediatek SoC MT8173.CK Hu
This patch adds an initial DRM driver for the Mediatek MT8173 DISP subsystem. It currently supports two fixed output streams from the OVL0/OVL1 sources to the DSI0/DPI0 sinks, respectively.
