2021-12-02dt-bindings: net: cdns,macb: Convert to json-schemaGeert Uytterhoeven1-60/+0
Convert the Cadence MACB/GEM Ethernet controller Device Tree binding documentation to json-schema. Re-add "cdns,gem" (removed in commit a217d8711da5c87f ("dt-bindings: Remove PicoXcell bindings")) as there are active users on non-PicoXcell platforms. Add missing "ether_clk" clock. Add missing properties.

2021-10-24dt-bindings: net: macb: Add mdio bus child nodeSean Anderson1-0/+4
This adds an optional mdio bus child node. If present, the mac will look for PHYs there instead of directly under the top-level node. This eliminates any ambiguity about whether child nodes are PHYs, and allows the MDIO bus to contain non-PHY devices.

PicoXcell has had nothing but treewide cleanups for at least the last 8 years and no signs of activity. The most recent activity is a yocto vendor kernel based on v3.0 in 2015.

Add the compatibility string documentation for SiFive FU540-C0000 interface. On the FU540, this driver also needs to read and write registers in a management IP block that monitors or drives boundary signals for the GEMGXL IP block that are not directly mapped to GEMGXL registers. Therefore, add additional range to "reg" property for SiFive GEMGXL management IP registers.

2019-05-06dt-bindings: doc: reflect new NVMEM of_get_mac_address behaviourPetr Štetiar1-3/+2
As of_get_mac_address now supports NVMEM under the hood, we need to update the bindings documentation with the new nvmem-cell* properties, which would mean copy&pasting a lot of redundant information to every binding documentation currently referencing some of the MAC address properties. So I've just removed all the references to the optional MAC address properties and replaced them with the small note referencing net/ethernet.txt file.

2019-04-19of_net: Fix residues after of_get_nvmem_mac_address removalPetr Štetiar1-0/+4
I've discovered following discrepancy in the bindings/net/ethernet.txt documentation, where it states following: - nvmem-cells: phandle, reference to an nvmem node for the MAC address; - nvmem-cell-names: string, should be "mac-address" if nvmem is to be.. which is actually misleading and confusing. There are only two ethernet drivers in the tree, cadence/macb and davinci which supports this properties. This nvmem-cell* properties were introduced in commit 9217e566bdee ("of_net: Implement of_get_nvmem_mac_address helper"), but commit afa64a72b862 ("of: net: kill of_get_nvmem_mac_address()") forget to properly clean up this parts. So this patch fixes the documentation by moving the nvmem-cell* properties at the appropriate places. While at it, I've removed unused include as well.

2015-12-15net/macb: add support for resetting PHY using GPIOGregory CLEMENT1-0/+3
With device tree it is no more possible to reset the PHY at board level. Furthermore, doing in the driver allow to power down the PHY when the network interface is no more used. This reset can't be done at the PHY driver level. The PHY must be able to answer the to the mii bus scan to let the kernel creating a PHY device. The patch introduces a new optional property "phy-reset-gpios" inspired from the one use for the FEC.

2014-02-19DT: net: document Ethernet bindings in one placeSergei Shtylyov1-5/+1
This patch is an attempt to gather the Ethernet related bindings in one file, like it's done in the MMC and some other subsystems. It should save some of the trouble of documenting several properties over and over in each binding document, instead only making reference to the main file. I have used the Embedded Power Architecture(TM) Platform Requirements (ePAPR) standard as a base for the properties description, also documenting some ad-hoc properties that have been introduced over time despite having direct analogs in ePAPR.
