From 209d52110a32c2069b5d870504e73fdb0e30fc51 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Ville=20Syrj=C3=A4l=C3=A4?= Date: Fri, 25 Jan 2013 21:44:48 +0200 Subject: [PATCH] drm/i915: Set the SR01 "screen off" bit in i915_redisable_vga() too MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit From BSpec / SR01 - Clocking Mode: "The following sequence must be used when disabling the VGA plane. Write SR01 to set bit 5 = 1 to disable video output. Wait for 100us. Disable the VGA plane via Bit 31 of the MMIO VGA control." So simply call i915_disable_vga() from i915_redisable_vga().
