Subject: [PATCH 3/3] hwmon: (nct6775) add MAXIMUS VII HERO.
Date: Mon, 22 Nov 2021 23:28:50 +0200 [thread overview]
Message-ID: <20211122212850.321542-4-pauk.denis@gmail.com> (raw)
In-Reply-To: <20211122212850.321542-1-pauk.denis@gmail.com>
ASUS MAXIMUS VII HERO board has got an nct6775 chip, but by default
there's no use of it because of resource conflict with WMI method.
This commit adds MAXIMUS VII HERO to the list of boards and provides
ACPI mutex name that can be used as shared lock with ASUS WMI.
Logic checks that mutex is available. If mutex is not available
tries to get chip version by ACPI WMI interface.
