From 44421c60c93f78a6d83358e57f22e8f0c1993dba Mon Sep 17 00:00:00 2001 From: Isaku Yamahata Date: Tue, 23 Mar 2021 13:52:26 -0700 Subject: isa/v582c686: Reinitialize ACPI PM device on reset MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Commit 6be8cf56bc8b made sure that SCI is enabled in PM1.CNT on reset in acpi_only mode by modifying acpi_pm1_cnt_reset() and that worked for q35 as expected. This patch adds reset ACPI PM related registers on vt82c686 reset time and de-assert sci. via_pm_realize() initializes acpi pm tmr, evt, cnt and gpe. Reset them on device reset.
