Subject: [PATCH v2 20/25] drm/mediatek: add ovl0/ovl0_2l usecase
Date: Wed, 27 Mar 2019 14:19:16 +0800 [thread overview]
Message-ID: <1553667561-25447-21-git-send-email-yongqiang.niu@mediatek.com> (raw)
In-Reply-To: <1553667561-25447-1-git-send-email-yongqiang.niu@mediatek.com>
From: Yongqiang Niu <yongqiang.niu@mediatek.com>
This patch add ovl0/ovl0_2l usecase
in ovl->ovl0_2l direct link usecase:
1. the crtc support layer number will 4+2
2. ovl0_2l background color input select ovl0 when crtc init
and disable it when crtc finish
3. config ovl0_2l layer, if crtc config layer number is
bigger than ovl0 support layers(max is 4)
