From e219ef912a025a5e80e6bc9622620100763285fc Mon Sep 17 00:00:00 2001 From: =?utf8?q?Ville=20Syrj=C3=A4l=C3=A4?= Date: Thu, 1 Oct 2020 18:16:38 +0300 Subject: [PATCH] drm/i915: Wait for eDP panel power cycle delay on reboot on all platforms MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Extend the eDP panel power cycle delay wait on reboot handling to cover all platforms. No reason to think that VLV/CHV are in any way special since the documentation states that the hardware power cycle delay goes back to its default value on reset, and that may not be enough for all panels.
