From a57bf53e294d2919f2bd1e0817c63105adf3c023 Mon Sep 17 00:00:00 2001 From: Jose Abreu Date: Thu, 25 May 2017 15:19:21 +0100 Subject: [PATCH] drm/atmel-hlcdc: Use crtc->mode_valid() callback Now that we have a callback to check if crtc supports a given mode we can use it in atmel-hlcdc so that we restrict the number of probbed modes to the ones we can actually display. Also, remove the mode_fixup() callback as this is no longer needed because mode_valid() will be called before.
