From 5424793452d134ec1a173bd748c757144f25b1e2 Mon Sep 17 00:00:00 2001 From: AngeloGioacchino Del Regno Date: Wed, 12 Feb 2025 11:00:09 +0100 Subject: [PATCH] soc: mediatek: mt8167-mmsys: Fix missing regval in all entries The mmsys routing table for this SoC was effectively missing initialization of the val variable of struct mtk_mmsys_routes: this means that `val` was incorrectly initialized to zero, hence the registers were wrongly initialized. Add the required regval to all of the entries of the routing table for this SoC to fix display controller functionality.
