From 7a8417845d6485596b6f1550a426b0831b3514c9 Mon Sep 17 00:00:00 2001 From: Neal Frager Date: Wed, 18 Dec 2024 13:01:29 +0000 Subject: [PATCH] board: zynqmp: zynqmp-sm-k26-revA: release DP from reset This releases the DP configuration from reset early on during the boot process for K26 SOM. It will also avoid the boot hang situation should any attempt be made to configure the DP registers while it is still in reset. Fixes the same issue as described by the commit 8b81010a2fe3 ("video: zynqmp: Add support for reset").
