[PATCH] PCI: Cadence: Add quirk for Gen2 controller to do autonomous speed change.

2020-09-18 Thread Nadeem Athani
Cadence controller will not initiate autonomous speed change if strapped as Gen2. The Retrain bit is set as a quirk to trigger this speed change. Signed-off-by: Nadeem Athani --- drivers/pci/controller/cadence/pcie-cadence-host.c | 13 + drivers/pci/controller/cadence/pcie-cadence.
