From aab800b1a405745ef4216e48df8c8b8ec7b8b67d Mon Sep 17 00:00:00 2001 From: Sean Rhodes Date: Mon, 17 Feb 2025 16:55:36 +0000 Subject: [PATCH] soc/intel/cnvi: Increase the reset delay to 160ms from 105ms The Intel reference code for Thunder Peak increase the reset delay to 160ms from 105ms seen on Jefferson Peak, Cyclone Peak and others. For the sake of 110ms, use 160ms to cover all use cases.
