From 8dd1e4d73fdbc4a533a58c2c74a72877257c558c Mon Sep 17 00:00:00 2001 From: Maxime Ripard Date: Wed, 19 Jun 2019 12:17:52 +0200 Subject: [PATCH] drm/atomic: Add a function to reset connector TV properties MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Commit 731514b446fe6748d5a55a3dff202efb45c7d8df upstream. Reworked as functions have been moved from drm_atomic_helper.[c|h] to drm_atomic_state_helper.[c|h]. During the connector reset, if that connector has a TV property, it needs to be reset to the value provided on the command line. Provide a helper to do that.
