Subject: [PATCH v4 5/6] drm/mediatek: dpi/dsi: change the getting possible_crtc way
Date: Tue, 4 Aug 2020 18:55:54 +0200 [thread overview]
Message-ID: <20200804165555.75159-7-linux@fw-web.de> (raw)
In-Reply-To: <20200804165555.75159-1-linux@fw-web.de>
From: Jitao Shi <jitao.shi@mediatek.com>
For current mediatek dsi encoder, its possible crtc is fixed in crtc
0, and mediatek dpi encoder's possible crtc is fixed in crtc 1. In
some SoC the possible crtc is not fixed in this case, so call
mtk_drm_find_possible_crtc_by_comp() to find out the correct possible
crtc.
