From c0940ebe428777c9fe5856d6b305d75ca3e610ae Mon Sep 17 00:00:00 2001 From: Helge Deller Date: Fri, 17 Nov 2023 16:43:52 +0100 Subject: [PATCH] parisc/power: Fix power soft-off when running on qemu commit 6ad6e15a9c46b8f0932cd99724f26f3db4db1cdf upstream. Firmware returns the physical address of the power switch, so need to use gsc_writel() instead of direct memory access.
