Subject: [PATCH v2 2/2] PCI: pciehp: Add HXT quirk for Command Completed errata
Date: Wed, 7 Nov 2018 15:25:05 +0800	[thread overview]
Message-ID: <5e88860c8426df537c5a5f2d0e6add6df8955a0f.1541574331.git.shunyong.yang@hxt-semitech.com> (raw)
In-Reply-To: <bcaf1d5d-23a6-d4e6-08e8-587daf6cca06@kernel.org>

The HXT SD4800 PCI controller does not set the Command Completed
bit unless writes to the Slot Command register change "Control"
bits.

This patch adds SD4800 to the quirk.
