2018-08-27drm/mediatek: update some variable name from ovl to compStu Hsieh
This patch update some variable name from ovl to comp Because RDMA would be first HW in ddp, the naming ovl should be change to comp. Signed-off-by: Stu Hsieh <stu.hsieh@mediatek.com> Signed-off-by: CK Hu <ck.hu@mediatek.com>
2018-08-27drm/mediatek: use layer_nr function to get layer number to init planeStu Hsieh
This patch use layer_nr function to get layer number to init plane When plane init in crtc create, it use the number of OVL layer to init plane. That's OVL can read 4 memory address. For mt2712 third ddp, it use RDMA to read memory. RDMA can read 1 memory address, so it just init one plane. For compatibility, this patch use mtk_ddp_comp_layer_nr function to get layer number from their HW component in ddp for plane init.

2017-02-21drm: mediatek: use vblank hooks in struct drm_crtc_funcsShawn Guo
The vblank hooks in struct drm_driver are deprecated and only meant for legacy drivers. For modern drivers with DRIVER_MODESET flag, the hooks in struct drm_crtc_funcs should be used instead.

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>
