Subject: [PATCH 6.1 18/25] xhci: Apply XHCI_RESET_TO_DEFAULT quirk to ADL-N
Date: Mon, 19 Dec 2022 20:22:57 +0100	[thread overview]
Message-ID: <20221219182944.179224131@linuxfoundation.org> (raw)
In-Reply-To: <20221219182943.395169070@linuxfoundation.org>

From: Reka Norman <rekanorman@chromium.org>

commit fed70b61ef2c0aed54456db3d485b215f6cc3209 upstream.

ADL-N systems have the same issue as ADL-P, where a large boot firmware
delay is seen if USB ports are left in U3 at shutdown. So apply the
XHCI_RESET_TO_DEFAULT quirk to ADL-N as well.

This patch depends on commit 34cd2db408d5 ("xhci: Add quirk to reset
host back to default state at shutdown").

The issue it fixes is a ~20s boot time delay when booting from S5. It
affects ADL-N devices, and ADL-N support was added starting from v5.16.
