2016-08-11drm/mediatek: set mt8173 dithering functionBibby Hsieh1-3/+5
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>
2016-08-11drm/mediatek: Add gamma correction.Bibby Hsieh1-0/+10
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>
2016-05-06drm/mediatek: Add DRM Driver for Mediatek SoC MT8173.CK Hu1-0/+150
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.
