2019-07-18doc: bindings: Add description for MDIO MUX dts nodesAlex Marginean
Adds a short bindings document describing the expected structure of a MDIO MUX dts node. This is based on Linux binding and the example is in fact copied from there.

2019-05-08net: phy: micrel: Use correct skew values on KSZ9021James Byrne
Commit ff7bd212cb8a ("net: phy: micrel: fix divisor value for KSZ9031 phy skew") fixed the skew value divisor for the KSZ9031, but left the code using the same divisor for the KSZ9021, which is incorrect. The preceding commit c16e69f702b1 ("net: phy: micrel: add documentation for Micrel KSZ90x1 binding") added the DTS documentation for the KSZ90x1, changing it from the equivalent file in the Linux kernel to correctly state that for this part the skew value is set in 120ps steps, whereas the Linux documentation and driver continue to this day to use the incorrect value of 200 that came from the original KSZ9021 datasheet before it was corrected in revision 1.2 (Feb 2014). This commit sorts out the resulting confusion in a consistent way by making the following changes: - Update the documentation to be clear about what the skew values mean, in the same was as for the KSZ9031. - Update the Micrel PHY driver to select the appropriate divisor for both parts. - Adjust all the device trees that state skew values for KSZ9021 PHYs to use values based on 120ps steps instead of 200ps steps. This will result in the same values being programmed into the skew registers as the equivalent device trees in the Linux kernel do, where it incorrectly uses 200ps steps (since that's where all these device trees were copied from).

2018-11-05net: Add MT7628 ethernet driverStefan Roese
This patch adds ethernet support for the MIPS based Mediatek MT76xx SoCs (e.g. MT7628 and MT7688), including a minimum setup of the integrated switch. This driver is loosly based on the driver version included in this MediaTek github repository: https://github.com/MediaTek-Labs/linkit-smart-uboot.git Tested on the MT7688 LinkIt smart-gateway and on the Gardena-smart-gateway.

2018-10-10net: phy: ti: Add binding for the CLK_OUT pin muxingJanine Hagemann
The DP83867 has a muxing option for the CLK_OUT pin. It is possible to set CLK_OUT for different channels. Create a binding to select a specific clock for CLK_OUT pin. Based on commit 9708fb630d19 ("net: phy: dp83867: Add binding for the CLK_OUT pin muxing option") of mainline linux kernel.

2018-10-10net: phy: ti: Add lane swapping support in the DP83867 TI's PHY driverJanine Hagemann
This patch adds support for enabling or disabling the lane swapping (called "port mirroring" in PHY's CFG4 register) feature of the DP83867 TI's PHY device. One use case is when bootstrap configuration enables this feature (because of e.g. LED_0 wrong wiring) so then one needs to disable it in software (at u-boot/Linux). Based on commit fc6d39c39581 ("net: phy: dp83867: Add lane swapping support in the DP83867 TI's PHY driver") of mainline linux kernel.

2017-03-26drivers/net/phy: add fixed-phy / fixed-link supportHannes Schmelzer
This patch adds support for having a "fixed-link" to some other MAC (like some embedded switch-device). For this purpose we introduce a new phy-driver, called "Fixed PHY". Fixed PHY works only with CONFIG_DM_ETH enabled, since the fixed-link is described with a subnode below ethernet interface. Most ethernet drivers (unfortunately not all are following same scheme for searching/attaching phys) are calling "phy_connect(...)" for getting a phy-device. At this point we link in, we search here for a subnode called "fixed- link", once found we start phy_device_create(...) with the special phy- id PHY_FIXED_ID (0xa5a55a5a). During init the "Fixed PHY" driver has registered with this id and now gets probed, during probe we get all the details about fixed-link out of dts, later on the phy reports this values.

2016-11-07dt: net: add DWC EQoS bindingStephen Warren
The Synopsys DWC EQoS is a configurable Ethernet MAC/DMA IP block which supports multiple options for bus type, clocking and reset structure, and feature list. This patch imports the binding from the Linux kernel, including my V3 patch to extend the binding to cover the Tegra186, which is applied for next-20160912. So far, my changes have been acked by Lars Persson, the original author of the binding.
