I have an idea not to modify binding document so you could be quicker to merge these patches. The idea is: 1. Keep the patch 'drm/mediatek: fix possible_crtcs', let DPI encoder support both crtc0 and crtc1. 2. For encoder and crtc, it could find each other by encoder->crtc and crtc->encoder_mask to configure hardware correctly.
