Subject: [PULL 8/9] isa/v582c686: Reinitialize ACPI PM device on reset
Date: Thu, 1 Apr 2021 14:03:10 -0400	[thread overview]
Message-ID: <20210401180235.226321-9-mst@redhat.com> (raw)
In-Reply-To: <20210401180235.226321-1-mst@redhat.com>

From: Isaku Yamahata <isaku.yamahata@intel.com>

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.
