phy: atheros: add device tree bindings and config

2020-05-07T15:05:00Z

Add support for configuring the CLK_25M pin as well as the RGMII I/O voltage by the device tree. By default the AT803x PHYs outputs the 25MHz clock of the XTAL input. But this output can also be changed by software to other frequencies. This commit introduces a generic way to configure this output. Also the PHY supports different RGMII I/O voltages: 1.5V, 1.8V and 2.5V. An internal LDO is able to provide 1.5V (default) and 1.8V. The 2.5V option needs an external supply voltage. This commit adds support to switch the internal LDO to 1.8V. Signed-off-by: Michael Walle Acked-by: Joe Hershberger

dt-bindings: net: dp83867: Remove binding doc from U-Boot tree

2020-03-09T23:11:25Z

U-Boot is having DT which doesn't cover all options currently supported by driver. DT binding is aligned with Linux kernel version available here. https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/Documentation/devicetree/bindings/net/ti,dp83867.txt Based on my talk with Grygorii Strashko better will be to remove it. Also Linux kernel bindings are being converted to yaml that's another reason to do it only at one place. Signed-off-by: Michal Simek Reviewed-by: Grygorii Strashko

doc: really get rid of Documentation/ directory

2019-12-13T18:01:53Z

Commit 656d8da9d2 (doc: Remove duplicated documentation directory) got rid of most of Documentation/. But there's still an obviously useless .gitignore left behind. Also, there's a copy of the linux kernel's net/ethernet.txt binding imported from v5.0, while the existing one in doc/ is from 4.0-rc1. So replace the latter by the former, and making Documentation/ finally empty. Signed-off-by: Rasmus Villemoes Reviewed-by: Simon Goldschmidt

doc: bindings: Aquantia PHY node binding

A couple of optional properties have been introduced for Aquantia PHY allowing the driver to set up wiring related configuration points that are otherwise driven by firmware. Signed-off-by: Alex Marginean Acked-by: Joe Hershberger

doc: bindings: add bindings document for PHY nodes

It defines that PHY nodes must be children on MDIO bus nodes and defines the only required property in U-Boot, reg. This property along with the example provided are copied over from Linux. Signed-off-by: Alex Marginean Acked-by: Joe Hershberger

dt-bindings: phy: dp83867: Add documentation for disabling clock output

2019-12-09T15:47:42Z

Based on commit 980066e6d964 ("dt-bindings: phy: dp83867: Add documentation for disabling clock output") of mainline linux kernel. The clock output is generally only used for testing and development and not used to daisy-chain PHYs. It's just a source of RF noise afterward. Add a mux value for "off". I've added it as another enumeration to the output property. In the actual PHY, the mux and the output enable are independently controllable. However, it doesn't seem useful to be able to describe the mux setting when the output is disabled. Document that PHY's default setting will be left as is if the property is omitted.

drivers: net: add marvell MDIO driver

2019-09-04T16:37:19Z

This patch adds a separate driver for the MDIO interface of the Marvell Ethernet controllers based on driver model. There are two reasons to have a separate driver rather than including it inside the MAC driver itself: *) The MDIO interface is shared by all Ethernet ports, so a driver must guarantee non-concurrent accesses to this MDIO interface. The most logical way is to have a separate driver that handles this single MDIO interface, used by all Ethernet ports. *) The MDIO interface is the same between the existing mv643xx_eth driver and the new mvneta/mvpp2 driver. Even though it is for now only used by the mvneta/mvpp2 driver, it will in the future be used by the mv643xx_eth driver as well. This driver supports SMI IEEE for 802.3 Clause 22 and XSMI for IEEE 802.3 Clause 45. This patch also adds device tree binding for marvell MDIO driver.

doc: bindings: add mdio.txt describing generic MDIO properties

2019-09-04T16:37:19Z

Adds a binding document for mdio. A notable deviation from corresponding Linux binding is the introduction of device-name optional property, which can be used to name MDIO buses. Two reset optional properties described by Linux binding are also not present as they don't seem to be used in U-Boot at this time.
