   Various examples are fixed due to that.
 
 - Sync dtc with upstream version v1.5.0-30-g702c1b6c0e73
 
 - Initial schemas for networking bindings. This includes ethernet, phy
   and mdio common bindings with several Allwinner and stmmac converted
   to the schema.
 
 - Conversion of more Arm top-level SoC/board bindings to DT schema
 
 - Conversion of PSCI binding to DT schema
 
 - Rework Arm CPU schema to coexist with other CPU schemas
 
 - Add a bunch of missing vendor prefixes and new ones for SoChip,
   Sipeed, Kontron, B&R Industrial Automation GmbH, and Espressif

* Power State Coordination Interface (PSCI)
Firmware implementing the PSCI functions described in ARM document number
ARM DEN 0022A ("Power State Coordination Interface System Software on ARM
processors") can be used by Linux to initiate various CPU-centric power
operations.
Issue A of the specification describes functions for CPU suspend, hotplug
and migration of secure software.
Functions are invoked by trapping to the privilege level of the PSCI
firmware (specified as part of the binding below) and passing arguments
in a manner similar to that specified by AAPCS:
r0 => 32-bit Function ID / return value
{r1 - r3} => Parameters
Note that the immediate field of the trapping instruction must be set
to #0.
Main node required properties:
- compatible : should contain at least one of:
* "arm,psci" : For implementations complying to PSCI versions prior
to 0.2.
For these cases function IDs must be provided.
* "arm,psci-0.2" : For implementations complying to PSCI 0.2.
Function IDs are not required and should be ignored by
an OS with PSCI 0.2 support, but are permitted to be
present for compatibility with existing software when
"arm,psci" is later in the compatible list.
* "arm,psci-1.0" : For implementations complying to PSCI 1.0.
PSCI 1.0 is backward compatible with PSCI 0.2 with
minor specification updates, as defined in the PSCI
specification[2].
- method : The method of calling the PSCI firmware. Permitted
values are:
"smc" : SMC #0, with the register assignments specified
in this binding.
"hvc" : HVC #0, with the register assignments specified
in this binding.
Main node optional properties:
- cpu_suspend : Function ID for CPU_SUSPEND operation
- cpu_off : Function ID for CPU_OFF operation
- cpu_on : Function ID for CPU_ON operation
- migrate : Function ID for MIGRATE operation
Device tree nodes that require usage of PSCI CPU_SUSPEND function (ie idle
state nodes, as per bindings in [1]) must specify the following properties:
- arm,psci-suspend-param
Usage: Required for state nodes[1] if the corresponding
idle-states node entry-method property is set
to "psci".
Value type: <u32>
Definition: power_state parameter to pass to the PSCI
suspend call.
Example:
Case 1: PSCI v0.1 only.
psci {
compatible = "arm,psci";
method = "smc";
cpu_suspend = <0x95c10000>;
cpu_off = <0x95c10001>;
cpu_on = <0x95c10002>;
migrate = <0x95c10003>;
};
Case 2: PSCI v0.2 only
psci {
compatible = "arm,psci-0.2";
method = "smc";
};
Case 3: PSCI v0.2 and PSCI v0.1.
A DTB may provide IDs for use by kernels without PSCI 0.2 support,
enabling firmware and hypervisors to support existing and new kernels.
These IDs will be ignored by kernels with PSCI 0.2 support, which will
use the standard PSCI 0.2 IDs exclusively.
psci {
compatible = "arm,psci-0.2", "arm,psci";
method = "hvc";
cpu_on = < arbitrary value >;
cpu_off = < arbitrary value >;

* Allwinner sun8i GMAC ethernet controller
This device is a platform glue layer for stmmac.
Please see stmmac.txt for the other unchanged properties.
Required properties:
- compatible: must be one of the following string:
"allwinner,sun8i-a83t-emac"
"allwinner,sun8i-h3-emac"
"allwinner,sun8i-r40-gmac"
"allwinner,sun8i-v3s-emac"
"allwinner,sun50i-a64-emac"
"allwinner,sun50i-h6-emac", "allwinner-sun50i-a64-emac"
- reg: address and length of the register for the device.
- interrupts: interrupt for the device
- interrupt-names: must be "macirq"
- clocks: A phandle to the reference clock for this device
- clock-names: must be "stmmaceth"
- resets: A phandle to the reset control for this device
- reset-names: must be "stmmaceth"
- phy-mode: See ethernet.txt
- phy-handle: See ethernet.txt
- syscon: A phandle to the device containing the EMAC or GMAC clock register
Optional properties:
- allwinner,tx-delay-ps: TX clock delay chain value in ps.
Range is 0-700. Default is 0.
Unavailable for allwinner,sun8i-r40-gmac
- allwinner,rx-delay-ps: RX clock delay chain value in ps.
Range is 0-3100. Default is 0.
Range is 0-700 for allwinner,sun8i-r40-gmac
Both delay properties need to be a multiple of 100. They control the
clock delay for external RGMII PHY. They do not apply to the internal
PHY or external non-RGMII PHYs.
Optional properties for the following compatibles:
- "allwinner,sun8i-h3-emac",
- "allwinner,sun8i-v3s-emac":
- allwinner,leds-active-low: EPHY LEDs are active low
Required child node of emac:
- mdio bus node: should be named mdio with compatible "snps,dwmac-mdio"
Required properties of the mdio node:
- #address-cells: shall be 1
- #size-cells: shall be 0
The device node referenced by "phy" or "phy-handle" must be a child node
of the mdio node. See phy.txt for the generic PHY bindings.
The following compatibles require that the emac node have a mdio-mux child
node called "mdio-mux":
- "allwinner,sun8i-h3-emac"
- "allwinner,sun8i-v3s-emac":
Required properties for the mdio-mux node:
- compatible = "allwinner,sun8i-h3-mdio-mux"
- mdio-parent-bus: a phandle to EMAC mdio
- one child mdio for the integrated mdio with the compatible
"allwinner,sun8i-h3-mdio-internal"
- one child mdio for the external mdio if present (V3s have none)
Required properties for the mdio-mux children node:
- reg: 1 for internal MDIO bus, 2 for external MDIO bus
The following compatibles require a PHY node representing the integrated
PHY, under the integrated MDIO bus node if an mdio-mux node is used:
- "allwinner,sun8i-h3-emac",
- "allwinner,sun8i-v3s-emac":
Additional information regarding generic multiplexer properties can be found
at Documentation/devicetree/bindings/net/mdio-mux.txt
Required properties of the integrated phy node:
- clocks: a phandle to the reference clock for the EPHY
- resets: a phandle to the reset control for the EPHY
- Must be a child of the integrated mdio
Example with integrated PHY:
emac: ethernet@1c0b000 {
compatible = "allwinner,sun8i-h3-emac";
syscon = <&syscon>;
reg = <0x01c0b000 0x104>;

The following properties are common to the Ethernet controllers:
NOTE: All 'phy*' properties documented below are Ethernet specific. For the
generic PHY 'phys' property, see
Documentation/devicetree/bindings/phy/phy-bindings.txt.
- mac-address: array of 6 bytes, specifies the MAC address that was last used by
the boot program; should be used in cases where the MAC address assigned to
the device by the boot program is different from the "local-mac-address"
property;
- local-mac-address: array of 6 bytes, specifies the MAC address that was
assigned to the network device;
- nvmem-cells: phandle, reference to an nvmem node for the MAC address
- nvmem-cell-names: string, should be "mac-address" if nvmem is to be used
- max-speed: number, specifies maximum speed in Mbit/s supported by the device;
- max-frame-size: number, maximum transfer unit (IEEE defined MTU), rather than
the maximum frame size (there's contradiction in the Devicetree
Specification).
- phy-mode: string, operation mode of the PHY interface. This is now a de-facto
standard property; supported values are:
* "internal" (Internal means there is not a standard bus between the MAC and
the PHY, something proprietary is being used to embed the PHY in the MAC.)
* "mii"
* "gmii"
* "sgmii"
* "qsgmii"
* "tbi"
* "rev-mii"
* "rmii"
* "rgmii" (RX and TX delays are added by the MAC when required)
* "rgmii-id" (RGMII with internal RX and TX delays provided by the PHY, the
MAC should not add the RX or TX delays in this case)
* "rgmii-rxid" (RGMII with internal RX delay provided by the PHY, the MAC
should not add an RX delay in this case)
* "rgmii-txid" (RGMII with internal TX delay provided by the PHY, the MAC
should not add an TX delay in this case)

* "usxgmii"
- phy-connection-type: the same as "phy-mode" property but described in the
Devicetree Specification;
- phy-handle: phandle, specifies a reference to a node representing a PHY
device; this property is described in the Devicetree Specification and so
preferred;
- phy: the same as "phy-handle" property, not recommended for new bindings.
- phy-device: the same as "phy-handle" property, not recommended for new
bindings.
- rx-fifo-depth: the size of the controller's receive fifo in bytes. This
is used for components that can have configurable receive fifo sizes,
and is useful for determining certain configuration settings such as
flow control thresholds.
- tx-fifo-depth: the size of the controller's transmit fifo in bytes. This
is used for components that can have configurable fifo sizes.
- managed: string, specifies the PHY management type. Supported values are:
"auto", "in-band-status". "auto" is the default, it usess MDIO for
management if fixed-link is not specified.
Child nodes of the Ethernet controller are typically the individual PHY devices
connected via the MDIO bus (sometimes the MDIO bus controller is separate).
They are described in the phy.txt file in this same directory.
For non-MDIO PHY management see fixed-link.txt.

Fixed link Device Tree binding
------------------------------
Some Ethernet MACs have a "fixed link", and are not connected to a
normal MDIO-managed PHY device. For those situations, a Device Tree
binding allows to describe a "fixed link".
Such a fixed link situation is described by creating a 'fixed-link'
sub-node of the Ethernet MAC device node, with the following
properties:
* 'speed' (integer, mandatory), to indicate the link speed. Accepted
values are 10, 100 and 1000
* 'full-duplex' (boolean, optional), to indicate that full duplex is
used. When absent, half duplex is assumed.
* 'pause' (boolean, optional), to indicate that pause should be
enabled.
* 'asym-pause' (boolean, optional), to indicate that asym_pause should
be enabled.
* 'link-gpios' ('gpio-list', optional), to indicate if a gpio can be read
to determine if the link is up.
Old, deprecated 'fixed-link' binding:
* A 'fixed-link' property in the Ethernet MAC node, with 5 cells, of the
form <a b c d e> with the following accepted values:
- a: emulated PHY ID, choose any but but unique to the all specified
fixed-links, from 0 to 31
- b: duplex configuration: 0 for half duplex, 1 for full duplex
- c: link speed in Mbits/sec, accepted values are: 10, 100 and 1000
- d: pause configuration: 0 for no pause, 1 for pause
- e: asymmetric pause configuration: 0 for no asymmetric pause, 1 for
asymmetric pause
Examples:
ethernet@0 {
...
fixed-link {
speed = <1000>;
full-duplex;
};
...
};
ethernet@1 {
...
fixed-link {
speed = <1000>;
pause;
link-gpios = <&gpio0 12 GPIO_ACTIVE_HIGH>;
};
...
};

Common MDIO bus properties.
These are generic properties that can apply to any MDIO bus.
Optional properties:
- reset-gpios: One GPIO that control the RESET lines of all PHYs on that MDIO
bus.
- reset-delay-us: RESET pulse width in microseconds.
A list of child nodes, one per device on the bus is expected. These
should follow the generic phy.txt, or a device specific binding document.
The 'reset-delay-us' indicates the RESET signal pulse width in microseconds and
applies to all PHY devices. It must therefore be appropriately determined based
on all PHY requirements (maximum value of all per-PHY RESET pulse widths).
Example :
This example shows these optional properties, plus other properties
required for the TI Davinci MDIO driver.
davinci_mdio: ethernet@5c030000 {
compatible = "ti,davinci_mdio";
reg = <0x5c030000 0x1000>;

reset-delay-us = <2>;

PHY nodes
Required properties:
- interrupts : interrupt specifier for the sole interrupt.
- reg : The ID number for the phy, usually a small integer
Optional Properties:
- compatible: Compatible list, may contain
"ethernet-phy-ieee802.3-c22" or "ethernet-phy-ieee802.3-c45" for
PHYs that implement IEEE802.3 clause 22 or IEEE802.3 clause 45
specifications. If neither of these are specified, the default is to
assume clause 22.
If the PHY reports an incorrect ID (or none at all) then the
"compatible" list may contain an entry with the correct PHY ID in the
form: "ethernet-phy-idAAAA.BBBB" where
AAAA - The value of the 16 bit Phy Identifier 1 register as
4 hex digits. This is the chip vendor OUI bits 3:18
BBBB - The value of the 16 bit Phy Identifier 2 register as
4 hex digits. This is the chip vendor OUI bits 19:24,
followed by 10 bits of a vendor specific ID.
The compatible list should not contain other values than those
listed here.
- max-speed: Maximum PHY supported speed (10, 100, 1000...)
- broken-turn-around: If set, indicates the PHY device does not correctly
release the turn around line low at the end of a MDIO transaction.
- enet-phy-lane-swap: If set, indicates the PHY will swap the TX/RX lanes to
compensate for the board being designed with the lanes swapped.
- enet-phy-lane-no-swap: If set, indicates that PHY will disable swap of the
TX/RX lanes. This property allows the PHY to work correcly after e.g. wrong
bootstrap configuration caused by issues in PCB layout design.
- eee-broken-100tx:
- eee-broken-1000t:
- eee-broken-10gt:
- eee-broken-1000kx:
- eee-broken-10gkx4:
- eee-broken-10gkr:
Mark the corresponding energy efficient ethernet mode as broken and
request the ethernet to stop advertising it.
- phy-is-integrated: If set, indicates that the PHY is integrated into the same
physical package as the Ethernet MAC. If needed, muxers should be configured
to ensure the integrated PHY is used. The absence of this property indicates
the muxers should be configured so that the external PHY is used.
- resets: The reset-controller phandle and specifier for the PHY reset signal.
- reset-names: Must be "phy" for the PHY reset signal.
- reset-gpios: The GPIO phandle and specifier for the PHY reset signal.
- reset-assert-us: Delay after the reset was asserted in microseconds.
If this property is missing the delay will be skipped.
- reset-deassert-us: Delay after the reset was deasserted in microseconds.
If this property is missing the delay will be skipped.
Example:
ethernet-phy@0 {
compatible = "ethernet-phy-id0141.0e90", "ethernet-phy-ieee802.3-c22";
interrupt-parent = <&PIC>;
interrupts = <35 IRQ_TYPE_EDGE_RISING>;
reg = <0>;
resets = <&rst 8>;
reset-names = "phy";
reset-gpios = <&gpio1 4 GPIO_ACTIVE_LOW>;
reset-assert-us = <1000>;
reset-deassert-us = <2000>;
