[PATCH v2] PCI: Add ACS quirk for NXP LX2160 and LX2162 C/E/N platforms

From: Wasim Khan
Date: Mon Aug 02 2021 - 11:57:02 EST


From: Wasim Khan <wasim.khan@xxxxxxx>

LX2160C : security features + CAN-FD
LX2160E : security features + CAN
LX2160N : without security features + CAN
LX2162C : security features + CAN-FD
LX2162E : security features + CAN
LX2162N : without security features + CAN

Root Ports in NXP LX2160 and LX2162 where each Root Port
is a Root Complex with unique segment numbers do provide
isolation features to disable peer transactions and
validate bus numbers in requests, but do not provide an
actual PCIe ACS capability.

Enable ACS quirk for NXP LX2160C/E/N and LX2162C/E/N platforms
