- Poll less aggressively and non-atomically for PME_TO_Ack during transition to L2 (Vidya Sagar) - Increase LTSSM poll time on surprise link down (Manikanta Maddireddy) - Disable LTSSM after transition to Detect on surprise link down to stop toggling between Polling and Detect (Manikanta Maddireddy) - Don't force the device into the D0 state before L2 when suspending or shutting down the controller (Vidya Sagar) - Disable PERST# IRQ only in Endpoint mode because it's not registered in Root Port mode (Manikanta Maddireddy) - Handle 'nvidia,refclk-select' as optional (Vidya Sagar) - Disable direct speed change in Endpoint mode so link speed change is controlled by the host (Vidya Sagar) - Set LTR values before link up to avoid bogus LTR messages with 0 latency (Vidya Sagar) - Allow system suspend when the Endpoint link is down (Vidya Sagar) - During remove, free resources allocated during Endpoint .probe() (Vidya Sagar) - Use DWC IP core version, not Tegra custom values, to avoid DWC core version check warnings (Manikanta Maddireddy) - Apply ECRC workaround to devices based on DesignWare 5.00a as well as 4.90a (Manikanta Maddireddy) - Disable PM Substate L1.2 in Endpoint mode to work around Tegra234 erratum (Vidya Sagar) - Delay post-PERST# cleanup until core is powered on to avoid CBB timeout (Manikanta Maddireddy) - Assert CLKREQ# so switches that forward it to their downstream side can bring up those links successfully (Vidya Sagar) - Calibrate pipe to UPHY for Endpoint mode to reset stale PLL state from any previous bad link state (Vidya Sagar) - Remove IRQF_ONESHOT flag from Endpoint interrupt registration so DMA driver and Endpoint controller driver can share the interrupt line (Vidya Sagar) - Enable DMA interrupt to support DMA in both Root Port and Endpoint modes (Vidya Sagar) - Enable hardware link retraining after link goes down in Endpoint mode (Vidya Sagar) - Add DT binding and driver support for core clock monitoring (Vidya Sagar) * pci/controller/dwc-tegra194: PCI: tegra194: Add core monitor clock support dt-bindings: PCI: tegra194: Add monitor clock support PCI: tegra194: Enable hardware hot reset mode in Endpoint mode PCI: tegra194: Enable DMA interrupt PCI: tegra194: Remove IRQF_ONESHOT flag during Endpoint interrupt registration PCI: tegra194: Calibrate pipe to UPHY for Endpoint mode PCI: tegra194: Assert CLKREQ# explicitly by default PCI: tegra194: Fix CBB timeout caused by DBI access before core power-on PCI: tegra194: Disable L1.2 capability of Tegra234 EP PCI: dwc: Apply ECRC workaround to DesignWare 5.00a as well PCI: tegra194: Use DWC IP core version PCI: tegra194: Free up Endpoint resources during remove() PCI: tegra194: Allow system suspend when the Endpoint link is not up PCI: tegra194: Set LTR message request before PCIe link up in Endpoint mode PCI: tegra194: Disable direct speed change for Endpoint mode PCI: tegra194: Use devm_gpiod_get_optional() to parse "nvidia,refclk-select" PCI: tegra194: Disable PERST# IRQ only in Endpoint mode PCI: tegra194: Don't force the device into the D0 state before L2 PCI: tegra194: Disable LTSSM after transition to Detect on surprise link down PCI: tegra194: Increase LTSSM poll time on surprise link down PCI: tegra194: Fix polling delay for L2 state
