Subject: dt-bindings: Add vendor prefix for Espressif

Add Espressif Systems DT vendor prefix. That prefix has been used for quite
some time for WiFi chips, but has never been documented.

Ignore disabled nodes in the memory-region
nodes list and continue to initialize the rest
of enabled nodes.

Check if the "reserved-memory" node is available
and if it's not available, return 0 to ignore the
"reserved-memory" node and continue parsing with
next node in memory-region nodes list.

Subject: dt-bindings: Remove Linuxisms from common-properties binding

We shouldn't reference Linux kernel functions or Linux itself in proper
bindings. It's OK to reference functions in the kernel when explaining
examples, but otherwise we shouldn't reference functions to describe
what the binding means.

Some functions in here are never called, and others are only called
during __init. Remove the dead code and some dead exports for functions
that don't exist (I'm looking at you of_fdt_get_string!). Mark some
functions with __init so we can throw them away after we boot up and
poke at the FDT blob too.

Subject: of/fdt: Mark initial_boot_params as __ro_after_init

The FDT pointer, i.e. initial_boot_params, shouldn't be changed after
init. It's only set by boot code and then the only user of the FDT is
the raw sysfs reading API. Mark this pointer with __ro_after_init so
that the pointer can't be changed after init.

Generated nodes for overlays begin with '_'. The binding examples are
built as overlays in order to allow unresolved phandles, so we need to
allow the generated node names.

Subject: dt-bindings: Check the examples against the schemas

Currently, the binding examples are just built with dtc. dtc recently
gained the support necessary to output the examples in YAML format
(commit 87963ee20693 ("livetree: add missing type markers in generated
overlay properties"). Now just switch the output format and the examples
will be checked against the schema.

Subject: dt-bindings: property-units: Sanitize unit naming

Make the naming of units consistent with common practices:
  - Do not capitalize the first character of units ("Celsius" is
    special, as it is not the unit name, but a reference to its
    proposer),
  - Do not use plural for units,
  - Do not abbreviate "ampere",
  - Concatenate prefixes and units (no spaces or hyphens),
  - Separate units by spaces not hyphens,
  - "milli" applies to "degree", not to "Celsius".

Subject: Documentation: arm: Link idle-states binding to "enable-method"
 property

The "enable-method" property for cpu nodes needs to be "psci" for CPU
idle management to be setup correctly.

Add a note to the binding documentation to this effect to make it
obvious.

When CONFIG_OF_EARLY_FLATTREE is disabled, there is a compiler
warning,

drivers/of/fdt.c:129:19: warning: ‘of_fdt_match’ defined but not used [-Wunused-function]
 static int __init of_fdt_match(const void *blob, unsigned long node,

Since the only caller of of_fdt_match() is of_flat_dt_match(),
let's move the body of of_fdt_match() into of_flat_dt_match()
and eliminate of_fdt_match().

Meanwhile, move of_fdt_is_compatible() under CONFIG_OF_EARLY_FLATTREE,
as all callers are over there.

-* 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 >;

-- 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.)

-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;
-	};

+description:
+  These are generic properties that can apply to any MDIO bus. Any
+  MDIO bus must have a list of child nodes, one per device on the
+  bus. These should follow the generic ethernet-phy.yaml document, or
+  a device specific binding document.

+      lines of all PHYs on that MDIO bus.
+
+  reset-delay-us:

+      RESET pulse width in microseconds. It applies to all PHY devices
+      and must therefore be appropriately determined based on all PHY

Subject: MAINTAINERS: Add Ethernet PHY YAML file

While the Ethernet PHY framework was marked as maintained, the device tree
bindings associated to that framework was not listed under the maintained
files. Fix that.

Subject: dt-bindings: net: phy: The interrupt property is not mandatory

Unlike what was initially claimed in the PHY binding, the interrupt
property of a PHY can be omitted, and the OS will turn to polling instead.

Document that.

Subject: dt-bindings: net: sun7i-gmac: Convert the binding to a schemas

Switch our Allwinner A20 GMAC controller binding to a YAML schema to enable
the DT validation. Since that controller is based on a Synopsys IP, let's
add the validation to that schemas with a bunch of conditionals.

Subject: dt-bindings: net: sun8i-emac: Convert the binding to a schemas

Switch our Allwinner H3 EMAC controller binding to a YAML schema to enable
the DT validation. Since that controller is based on a Synopsys IP, let's
add the validation to that schemas with a bunch of conditionals.

-* 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

Subject: dt-bindings: net: dwmac: Deprecate the PHY reset properties

Even though the DWMAC driver uses some driver specific properties, the PHY
core has a bunch of generic properties and can deal with them nicely.

Let's deprecate our specific properties.

Subject: dt-bindings: backlight: lm3630a: correct schema validation

The '#address-cells' and '#size-cells' properties were not defined in
the lm3630a bindings and would cause the following error when
attempting to validate the examples against the schema:

Documentation/devicetree/bindings/leds/backlight/lm3630a-backlight.example.dt.yaml:
'#address-cells', '#size-cells' do not match any of the regexes:
'^led@[01]$', 'pinctrl-[0-9]+'

Correct this by adding those two properties.

While we're here, move the ti,linear-mapping-mode property to the
led@[01] child nodes to correct the following validation error:

Documentation/devicetree/bindings/leds/backlight/lm3630a-backlight.example.dt.yaml:
led@0: 'ti,linear-mapping-mode' does not match any of the regexes:
'pinctrl-[0-9]+'

Subject: dt-bindings: arm: Limit cpus schema to only check Arm 'cpu' nodes

Matching on the 'cpus' node was a bad choice because the schema is
incorrectly applied to non-Arm cpus nodes. As we now have a common cpus
schema which checks the general structure, it is also redundant to do so
in the Arm CPU schema.

The downside is one could conceivably mix different architecture's cpu
nodes or have typos in the compatible string. The latter problem pretty
much exists for every schema.

Both the allwinner and amlogic compatibles require that either the
allwinner,pipeline or the amlogic,pipeline property is set. This was
dropped during the conversion since we didn't have conditionals back then,
but we can express this properly now.

Subject: dt-bindings: net: Use phy-mode instead of phy-connection-type

When adding support for the DWMAC (and derivatives) bindings,
phy-connection-type was required, even though the previous binding required
the equivalent phy-mode.

Let's fix this by using phy-mode as we should have.

To support Rx in-band wakeup, one must create an interrupt specifier with
edge sensitivity on Rx pin and an addtional pinctrl to reconfigure Rx pin
to normal GPIO in sleep state. Driver will switch to sleep mode pinctrl and
enable irq wake before suspend and restore to default settings when
resuming.
