Subject: [PATCH 7/7] ACPI: scan: Add some HIDs which are never bound on Cherry Trail devices to acpi_ignore_dep_hids
Date: Sat, 21 Nov 2020 21:30:40 +0100	[thread overview]
Message-ID: <20201121203040.146252-8-hdegoede@redhat.com> (raw)
In-Reply-To: <20201121203040.146252-1-hdegoede@redhat.com>

Add some HIDs which are found on Cherry Trail devices and which
Linux never bounds to acpi_ignore_dep_hids. This allows all root
level ACPI devices to be instantiated during step one of scanning
the ACPI root.

Note this is not strictly necessary, at least not on the one
Cherry Trail device this has been tested on so far.
