dt-bindings: drop redundant part of title of shared bindings

2022-12-16T17:41:49Z

The Devicetree bindings document does not have to say in the title that it is a "binding", but instead just describe the hardware. For shared (re-usable) schemas, name them all as "common properties".

dt-bindings: net: mdio: Drop resets/reset-names child properties

2022-01-12T16:00:22Z

resets/reset-names are device specific and don't belong in the MDIO bus schema. For example, it doesn't match what is defined for the "qca,ar9331-switch" binding which defines "reset-names" to be "switch" rather than "phy". Neither name is that useful IMO. Other child properties are also device specific, but those won't conflict with device schemas. Signed-off-by: Rob Herring Link: https://lore.kernel.org/r/20220111170248.3160841-1-robh@kernel.org

dt-bindings: net: mdio: Allow any child node name

2022-01-10T01:09:35Z

An MDIO bus can have devices other than ethernet PHYs on it, so it should allow for any node name rather than just 'ethernet-phy'. Cc: Andrew Lunn Cc: Heiner Kallweit Cc: Russell King Cc: "David S.

dt-bindings: Fix JSON pointers

2020-12-18T21:14:44Z

The correct syntax for JSON pointers begins with a '/' after the '#'. Without a '/', the string should be interpreted as a subschema identifier. The jsonschema module currently doesn't handle subschema identifiers and incorrectly allows JSON pointers to begin without a '/'. Let's fix this before it becomes a problem when jsonschema module is fixed.

dt-bindings: Explicitly allow additional properties in common schemas

2020-10-07T16:30:06Z

In order to add meta-schema checks for additional/unevaluatedProperties being present, all schema need to make this explicit. As common/shared schema are included by other schemas, they should always allow for additionalProperties.

dt-bindings: net: mdio: add reset-post-delay-us property

2020-08-03T22:01:02Z

Add "reset-post-delay-us" parameter to MDIO bus properties, so it's possible to add a delay after reset deassert. This is optional in case external hardware slows down release of the reset signal.

dt-bindings: net: mdio: Make descriptions more general

2020-04-22T18:43:19Z

A number of descriptions assume a PHY device, but since this binding describes a MDIO bus which can have different kinds of MDIO devices attached to it, rephrase some descriptions to be more general in that regard.

Some of the properties pertaining to the broken turn around or resets were only documented in ethernet-phy.yaml while they are applicable across all MDIO devices and not Ethernet PHYs specifically which are a superset.

net: ethernet: fec: Allow the MDIO preamble to be disabled

2020-04-20T19:37:08Z

An MDIO transaction normally starts with 32 1s as a preamble. However not all devices requires such a preamble. Add a device tree property which allows the preamble to be suppressed. This will half the size of the MDIO transaction, allowing faster transactions. But it should only be used when all devices on the bus support suppressed preamble.

net: ethernet: fec: Allow configuration of MDIO bus speed

2020-04-20T19:37:08Z

MDIO busses typically operate at 2.5MHz. However many devices can operate at faster speeds. This then allows more MDIO transactions per second, useful for Ethernet switch statistics, or Ethernet PHY TDR data. Allow the bus speed to be configured, using the standard "clock-frequency" property, which i2c busses use to indicate the bus speed. Before using this property, ensure all devices on the bus do actually support the requested clock speed.
