Merge tag 'devicetree-for-5.3' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux
Pull Devicetree updates from Rob Herring: - DT binding schema examples are now validated against the schemas. 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 - Add Mediatek UART RX wakeup support to binding - Add reset to ST UART binding - Remove some Linuxisms from the endianness common-properties.txt binding - Make the flattened DT read-only after init - Ignore disabled reserved memory nodes - Clean-up some dead code in FDT functions * tag 'devicetree-for-5.3' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux: (56 commits) dt-bindings: vendor-prefixes: add Sipeed dt-bindings: vendor-prefixes: add SoChip dt-bindings: 83xx-512x-pci: Drop cell-index property dt-bindings: serial: add documentation for Rx in-band wakeup support dt-bindings: arm: Convert RDA Micro board/soc bindings to json-schema of: unittest: simplify getting the adapter of a client of/fdt: pass early_init_dt_reserve_memory_arch() with bool type nomap of/platform: Drop superfluous cast in of_device_make_bus_id() dt-bindings: usb: ehci: Fix example warnings dt-bindings: net: Use phy-mode instead of phy-connection-type dt-bindings: simple-framebuffer: Add requirement for pipelines dt-bindings: display: Fix simple-framebuffer example dt-bindings: net: mdio: Add child nodes dt-bindings: net: mdio: Add address and size cells dt-bindings: net: mdio: Add a nodename pattern dt-bindings: mtd: sunxi-nand: Drop 'maxItems' from child 'reg' property dt-bindings: arm: Limit cpus schema to only check Arm 'cpu' nodes dt-bindings: backlight: lm3630a: correct schema validation dt-bindings: net: dwmac: Deprecate the PHY reset properties dt-bindings: net: sun8i-emac: Convert the binding to a schemas ...

-* 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.

- 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

-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 {

-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

-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>;

- reset-assert-us = <1000>;
- reset-deassert-us = <2000>;
