Subject: [PATCH v4 03/13] dt-bindings: net: Add a YAML schemas for the generic MDIO options
Date: Thu, 27 Jun 2019 17:31:45 +0200 [thread overview]
Message-ID: <e99ff7377a0d3d140cf62200fd9d62c108dac24e.1561649505.git-series.maxime.ripard@bootlin.com> (raw)
In-Reply-To: <cover.e80da8845680a45c2e07d5f17280fdba84555b8a.1561649505.git-series.maxime.ripard@bootlin.com>
The MDIO buses have a number of available device tree properties that can
be used in their device tree node. Add a YAML schemas for those.
Suggested-by: Andrew Lunn <andrew@lunn.ch>

-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>;
- #address-cells = <1>;
- #size-cells = <0>;
-
- reset-gpios = <&gpio2 5 GPIO_ACTIVE_LOW>;
- reset-delay-us = <2>;
-
- ethphy0: ethernet-phy@1 {
- reg = <1>;
- };
-
- ethphy1: ethernet-phy@3 {
- reg = <3>;
- };
- };
