Subject: [PATCH] PCI: Add HXT vendor ID and ACS quirk
Date: Mon, 5 Nov 2018 11:15:59 +0800 [thread overview]
Message-ID: <1541387759-2336-1-git-send-email-shunyong.yang@hxt-semitech.com> (raw)
Add the HXT vendor ID to pci_ids.h and use it in quirks. As the
design of HXT SD4800 ACS feature is the same as QCOM QDF2xxx,
pci_quirk_qcom_rp_acs() is reused for SD4800 quirk.
