Subject: [PATCH v2 4/5] drm/mediatek: dpi/dsi: change the getting possible_crtc way
Date: Tue, 28 Jul 2020 13:17:59 +0200
Message-ID: <20200728111800.77641-5-frank-w@public-files.de> (raw)

From: Jitao Shi <jitao.shi@mediatek.com>

[Detail]
dpi/dsi get the possible_crtc by
mtk_drm_find_possible_crtc_by_comp(*drm_dev, ddp_comp)

Test: build pass and boot to logo
