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 ...

+Device tree binding for NVIDIA Tegra XUSB pad controller
+========================================================
+
+The Tegra XUSB pad controller manages a set of I/O lanes (with differential
+signals) which connect directly to pins/pads on the SoC package. Each lane
+is controlled by a HW block referred to as a "pad" in the Tegra hardware
+documentation. Each such "pad" may control either one or multiple lanes,
+and thus contains any logic common to all its lanes. Each lane can be
+separately configured and powered up.
+
+Some of the lanes are high-speed lanes, which can be used for PCIe, SATA or
+super-speed USB. Other lanes are for various types of low-speed, full-speed
+or high-speed USB (such as UTMI, ULPI and HSIC). The XUSB pad controller
+contains a software-configurable mux that sits between the I/O controller
+ports (e.g. PCIe) and the lanes.
+
+In addition to per-lane configuration, USB 3.0 ports may require additional
+settings on a per-board basis.
+
+Pads will be represented as children of the top-level XUSB pad controller
+device tree node. Each lane exposed by the pad will be represented by its
+own subnode and can be referenced by users of the lane using the standard
+PHY bindings, as described by the phy-bindings.txt file in this directory.
+
+The Tegra hardware documentation refers to the connection between the XUSB
+pad controller and the XUSB controller as "ports". This is confusing since
+"port" is typically used to denote the physical USB receptacle. The device
+tree binding in this document uses the term "port" to refer to the logical
+abstraction of the signals that are routed to a USB receptacle (i.e. a PHY
+for the USB signal, the VBUS power supply, the USB 2.0 companion port for
+USB 3.0 receptacles, ...).
+
+Required properties:
+--------------------
+- compatible: Must be:
+ - Tegra124: "nvidia,tegra124-xusb-padctl"
+ - Tegra132: "nvidia,tegra132-xusb-padctl", "nvidia,tegra124-xusb-padctl"
+ - Tegra210: "nvidia,tegra210-xusb-padctl"
+- reg: Physical base address and length of the controller's registers.
+- resets: Must contain an entry for each entry in reset-names.
+- reset-names: Must include the following entries:
+ - "padctl"
+
+
+Pad nodes:
+==========
+
+A required child node named "pads" contains a list of subnodes, one for each
+of the pads exposed by the XUSB pad controller. Each pad may need additional
+resources that can be referenced in its pad node.
+
+The "status" property is used to enable or disable the use of a pad. If set
+to "disabled", the pad will not be used on the given board. In order to use
+the pad and any of its lanes, this property must be set to "okay".
+
+For Tegra124 and Tegra132, the following pads exist: usb2, ulpi, hsic, pcie
+and sata. No extra resources are required for operation of these pads.
+
+For Tegra210, the following pads exist: usb2, hsic, pcie and sata. Below is
+a description of the properties of each pad.
+
+UTMI pad:
+---------
+
+Required properties:
+- clocks: Must contain an entry for each entry in clock-names.
+- clock-names: Must contain the following entries:
+ - "trk": phandle and specifier referring to the USB2 tracking clock
+
+HSIC pad:
+---------
+
+Required properties:
+- clocks: Must contain an entry for each entry in clock-names.
+- clock-names: Must contain the following entries:
+ - "trk": phandle and specifier referring to the HSIC tracking clock
+
+PCIe pad:
+---------
+
+Required properties:
+- clocks: Must contain an entry for each entry in clock-names.
+- clock-names: Must contain the following entries:
+ - "pll": phandle and specifier referring to the PLLE
+- resets: Must contain an entry for each entry in reset-names.
+- reset-names: Must contain the following entries:
+ - "phy": reset for the PCIe UPHY block
+
+SATA pad:
+---------
+
+Required properties:
+- resets: Must contain an entry for each entry in reset-names.
+- reset-names: Must contain the following entries:
+ - "phy": reset for the SATA UPHY block
+
+
+PHY nodes:
+==========
+
+Each pad node has a child named "lanes" that contains one or more children of
+its own, each representing one of the lanes controlled by the pad.
+
+Required properties:
+--------------------
+- status: Defines the operation status of the PHY. Valid values are:
+ - "disabled": the PHY is disabled
+ - "okay": the PHY is enabled
+- #phy-cells: Should be 0. Since each lane represents a single PHY, there is
+ no need for an additional specifier.
+- nvidia,function: The output function of the PHY. See below for a list of
+ valid functions per SoC generation.
+
+For Tegra124 and Tegra132, the list of valid PHY nodes is given below:
+- usb2: usb2-0, usb2-1, usb2-2
+ - functions: "snps", "xusb", "uart"
+- ulpi: ulpi-0
+ - functions: "snps", "xusb"
+- hsic: hsic-0, hsic-1
+ - functions: "snps", "xusb"
+- pcie: pcie-0, pcie-1, pcie-2, pcie-3, pcie-4
+ - functions: "pcie", "usb3-ss"
+- sata: sata-0
+ - functions: "usb3-ss", "sata"
+
+For Tegra210, the list of valid PHY nodes is given below:
+- utmi: utmi-0, utmi-1, utmi-2, utmi-3
+ - functions: "snps", "xusb", "uart"
+- hsic: hsic-0, hsic-1
+ - functions: "snps", "xusb"
+- pcie: pcie-0, pcie-1, pcie-2, pcie-3, pcie-4, pcie-5, pcie-6
+ - functions: "pcie-x1", "usb3-ss", "pcie-x4"
+- sata: sata-0
+ - functions: "usb3-ss", "sata"
+
+
+Port nodes:
+===========
+
+A required child node named "ports" contains a list of all the ports exposed
+by the XUSB pad controller. Per-port configuration is only required for USB.
+
+USB2 ports:

Device tree binding for NVIDIA Tegra XUSB pad controller
========================================================
+NOTE: It turns out that this binding isn't an accurate description of the XUSB
+pad controller. While the description is good enough for the functional subset
+required for PCIe and SATA, it lacks the flexibility to represent the features
+needed for USB. For the new binding, see ../phy/nvidia,tegra-xusb-padctl.txt.
+The binding described in this file is deprecated and should not be used.
+
The Tegra XUSB pad controller manages a set of lanes, each of which can be
assigned to one out of a set of different pads. Some of these pads have an
associated PHY that must be powered up before the pad can be used.
