Merge tag 'armsoc-drivers' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC driver updates from Arnd Bergmann: "Driver updates for ARM SoCs, these contain various things that touch the drivers/ directory but got merged through arm-soc for practical reasons. For the most part, this is now related to power management controllers, which have not yet been abstracted into a separate subsystem, and typically require some code in drivers/soc or arch/arm to control the power domains. Another large chunk here is a rework of the NVIDIA Tegra USB3.0 support, which was surprisingly tricky and took a long time to get done. Finally, reset controller handling as always gets merged through here as well" * tag 'armsoc-drivers' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (97 commits) arm-ccn: Enable building as module soc/tegra: pmc: Add generic PM domain support usb: xhci: tegra: Add Tegra210 support usb: xhci: Add NVIDIA Tegra XUSB controller driver dt-bindings: usb: xhci-tegra: Add Tegra210 XUSB controller support dt-bindings: usb: Add NVIDIA Tegra XUSB controller binding PCI: tegra: Support per-lane PHYs dt-bindings: pci: tegra: Update for per-lane PHYs phy: tegra: Add Tegra210 support phy: Add Tegra XUSB pad controller support dt-bindings: phy: tegra-xusb-padctl: Add Tegra210 support dt-bindings: phy: Add NVIDIA Tegra XUSB pad controller binding phy: core: Allow children node to be overridden clk: tegra: Add interface to enable hardware control of SATA/XUSB PLLs drivers: firmware: psci: make two helper functions inline soc: renesas: rcar-sysc: Add support for R-Car H3 power areas soc: renesas: rcar-sysc: Add support for R-Car E2 power areas soc: renesas: rcar-sysc: Add support for R-Car M2-N power areas soc: renesas: rcar-sysc: Add support for R-Car M2-W power areas soc: renesas: rcar-sysc: Add support for R-Car H2 power areas ...
