Merge branch 'lorenzo/pci/tegra'
- Fix Tegra OF node reference leak (Nishka Dasgupta) - Add #defines for PCIe Data Link Feature and Physical Layer 16.0 GT/s features (Vidya Sagar) - Disable MSI for Tegra Root Ports since they don't support using MSI for all Root Port events (Vidya Sagar) - Group DesignWare write-protected register writes together (Vidya Sagar) - Move DesignWare capability search interfaces so they can be used by both host and endpoint drivers (Vidya Sagar) - Add DesignWare extended capability search interfaces (Vidya Sagar) - Export dw_pcie_wait_for_link() so drivers can be modules (Vidya Sagar) - Add "snps,enable-cdm-check" DT binding for Configuration Dependent Module (CDM) register checking (Vidya Sagar) - Add DesignWare support for "snps,enable-cdm-check" CDM checking (Vidya Sagar) - Add "supports-clkreq" DT binding for host drivers to decide whether to advertise low power features (Vidya Sagar) - Add DT binding for Tegra194 (Vidya Sagar) - Add DT binding for Tegra194 P2U (PIPE to UPHY) block (Vidya Sagar) - Add support for Tegra194 P2U (PIPE to UPHY) (Vidya Sagar) - Add support for Tegra194 host controller (Vidya Sagar) - Add Tegra support for sideband PERST# and CLKREQ# for C5 (Vidya Sagar) - Add Tegra support for slot regulators for p2972-0000 platform (Vidya Sagar) * lorenzo/pci/tegra: arm64: tegra: Add PCIe slot supply information in p2972-0000 platform arm64: tegra: Add configuration for PCIe C5 sideband signals PCI: tegra: Add support to enable slot regulators PCI: tegra: Add support to configure sideband pins dt-bindings: PCI: tegra: Add PCIe slot supplies regulator entries dt-bindings: PCI: tegra: Add sideband pins configuration entries PCI: tegra: Add Tegra194 PCIe support phy: tegra: Add PCIe PIPE2UPHY support dt-bindings: PHY: P2U: Add Tegra194 P2U block dt-bindings: PCI: tegra: Add device tree support for Tegra194 dt-bindings: Add PCIe supports-clkreq property PCI: dwc: Add support to enable CDM register check dt-bindings: PCI: designware: Add binding for CDM register check PCI: dwc: Export dw_pcie_wait_for_link() API PCI: dwc: Add extended configuration space capability search API PCI: dwc: Move config space capability search API PCI: dwc: Group DBI registers writes requiring unlocking PCI: Disable MSI for Tegra root ports PCI: Add #defines for some of PCIe spec r4.0 features PCI: tegra: Fix OF node reference leak
