From f2d66aad1aade34df678177c5ccb58feaea72156 Mon Sep 17 00:00:00 2001 From: Russell King Date: Sun, 3 Nov 2013 15:52:16 +0000 Subject: [PATCH] imx-drm: simplify setup of panel format The encoder format passed into imx_drm_crtc_panel_format*() is the encoder format used for DRM in most cases; the HDMI encoder sets this to none, but this is incorrect, it should be TMDS. Since this is the case, we can pass the drm_encoder structure directly into this function and use the supplied fields there to configure the CRTC.
