2020-06-01lan743x: Added fixed link and RGMII supportRoelof Berg1-2/+2
Microchip lan7431 is frequently connected to a phy. However, it can also be directly connected to a MII remote peer without any phy in between. For supporting such a phyless hardware setup in Linux we utilized phylib, which supports a fixed-link configuration via the device tree. And we added support for defining the connection type R/GMII in the device tree. New behavior: ------------- . The automatic speed and duplex detection of the lan743x silicon between mac and phy is disabled. Instead phylib is used like in other typical Linux drivers. The usage of phylib allows to specify fixed-link parameters in the device tree. . The device tree entry phy-connection-type is supported now with the modes RGMII or (G)MII (default). Development state: ------------------ . Tested with fixed-phy configurations. Not yet tested in normal configurations with phy. Microchip kindly offered testing as soon as the Corona measures allow this. . All review findings of Andrew Lunn are included Example: -------- &pcie { status = "okay"; host@0 { reg = <0 0 0 0 0>; #address-cells = <3>; #size-cells = <2>; ethernet@0 { compatible = "weyland-yutani,noscom1", "microchip,lan743x"; status = "okay"; reg = <0 0 0 0 0>; phy-connection-type = "rgmii"; fixed-link { speed = <100>; full-duplex; }; }; }; }; Signed-off-by: Roelof Berg <rberg@berg-solutions.de> Signed-off-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: David S.

2019-01-26lan743x: Provide Read/Write Access to on chip OTPBryan Whitehead1-47/+170
The LAN743x includes on chip One-Time-Programmable (OTP) memory. This patch extends the ethtool EEPROM read/write interface to access OTP memory space. The currently existing interface is limited, as it does not allow OTP read, and OTP writes are restricted to offset==0, length==512, and data[0]==0xF3. This patch removes these restrictions and adds a private flag called OTP_ACCESS, which is used to switch between EEPROM, and OTP modes. The private flag OTP_ACCESS is configurable through the ethtool --set-priv-flags command. And visible through the ethtool --show-priv-flags command. By default OTP_ACCESS is false, and there for previously existing EEPROM commands will work exactly the same. However now access to OTP requires one extra step of setting OTP_ACCESS to true. This flag controls the read, write, and length reporting, functions of ethtool. EEPROM presence is not checked when setting or clearing this flag. If the EEPROM is not present, the user, as before, will need to diagnose that using existing read and write function of ethtool, while OTP_ACCESS is false. Updates for V2: Added comments as to why this patch is needed. Added comments explaining that EEPROM presence is not check when setting or clearing the OTP_ACCESS flag. Added length checking to all otp/eeprom read/write functions. Signed-off-by: Bryan Whitehead <Bryan.Whitehead@microchip.com> Signed-off-by: David S. Miller <davem@davemloft.net>
