Aside: There's a few other fb_create implementations which simply check for valid buffer format (or an approximation thereof), and then call drm_gem_fb_create. For atomic drivers at least we could walk all planes and make sure the format/modifier combo is valid, and remove even more code. For non-atomic drivers that's not possible, since the format list for the primary buffer might be garbage (and most likely it is). Also delete mtk_drm_fb.[hc] since it would now only contain one function.

2019-10-09drm/mediatek: add ovl0/ovl_2l0 usecaseYongqiang Niu
This patch add ovl0/ovl_2l0 usecase in ovl->ovl_2l0 direct link usecase: 1. the crtc support layer number will 4+2 2. ovl_2l0 background color input select ovl0 when crtc init and disable it when crtc finish 3. config ovl_2l0 layer, if crtc config layer number is bigger than ovl0 support layers(max is 4) Signed-off-by: Yongqiang Niu <yongqiang.niu@mediatek.com> Signed-off-by: CK Hu <ck.hu@mediatek.com>

2019-10-09drm/mediatek: add background color input select function for ovl/ovl_2lYongqiang Niu
This patch add background color input select function for ovl/ovl_2l ovl include 4 DRAM layer and 1 background color layer ovl_2l include 4 DRAM layer and 1 background color layer DRAM layer frame buffer data from render hardware, GPU for example. backgournd color layer is embed in ovl/ovl_2l, we can only set it color, but not support DRAM frame buffer. for ovl0->ovl0_2l direct link usecase, we need set ovl0_2l background color intput select from ovl0 if render send DRAM buffer layer number <=4, all these layer read by ovl. layer0 is at the bottom of all layers. layer3 is at the top of all layers. if render send DRAM buffer layer numbfer >=4 && <=6 ovl0 read layer0~3 ovl0_2l read layer4~5 layer5 is at the top ot all these layers. the decision of how to setting ovl0/ovl0_2l read these layer data is controlled in mtk crtc, which will be another patch Signed-off-by: Yongqiang Niu <yongqiang.niu@mediatek.com> Signed-off-by: CK Hu <ck.hu@mediatek.com>
