drm/mediatek: Add DRM Driver for Mediatek SoC MT8173. 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.

drm/mediatek: set mt8173 dithering function 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>

drm/atomic: Pass the full state to planes atomic disable and update The current atomic helpers have either their object state being passed as an argument or the full atomic state. The former is the pattern that was done at first, before switching to the latter for new hooks or when it was needed.
