2019-08-06net: dsa: dump CPU port regs through masterVivien Didelot
Merge the CPU port registers dump into the master interface registers dump through ethtool, by nesting the ethtool_drvinfo and ethtool_regs structures of the CPU port into the dump. drvinfo->regdump_len will contain the full data length, while regs->len will contain only the master interface registers dump length. This allows for example to dump the CPU port registers on a ZII Dev C board like this: # ethtool -d eth1 0x004: 0x00000000 0x008: 0x0a8000aa 0x010: 0x01000000 0x014: 0x00000000 0x024: 0xf0000102 0x040: 0x6d82c800 0x044: 0x00000020 0x064: 0x40000000 0x084: RCR (Receive Control Register) 0x47c00104 MAX_FL (Maximum frame length) 1984 FCE (Flow control enable) 0 BC_REJ (Broadcast frame reject) 0 PROM (Promiscuous mode) 0 DRT (Disable receive on transmit) 0 LOOP (Internal loopback) 0 0x0c4: TCR (Transmit Control Register) 0x00000004 RFC_PAUSE (Receive frame control pause) 0 TFC_PAUSE (Transmit frame control pause) 0 FDEN (Full duplex enable) 1 HBC (Heartbeat control) 0 GTS (Graceful transmit stop) 0 0x0e4: 0x76735d6d 0x0e8: 0x7e9e8808 0x0ec: 0x00010000 . . . 88E6352 Switch Port Registers ------------------------------ 00: Port Status 0x4d04 Pause Enabled 0 My Pause 1 802.3 PHY Detected 0 Link Status Up Duplex Full Speed 100 or 200 Mbps EEE Enabled 0 Transmitter Paused 0 Flow Control 0 Config Mode 0x4 01: Physical Control 0x003d RGMII Receive Timing Control Default RGMII Transmit Timing Control Default 200 BASE Mode 100 Flow Control's Forced value 0 Force Flow Control 0 Link's Forced value Up Force Link 1 Duplex's Forced value Full Force Duplex 1 Force Speed 100 or 200 Mbps . . .

Ido Schimmel says: ==================== drop_monitor: Various improvements and cleanups This patchset performs various improvements and cleanups in drop monitor with no functional changes intended. There are no changes in these patches relative to the RFC I sent two weeks ago [1].

Last patch enables the ENETC port 1 and its RGMII PHY on the LS1028A QDS board, where the MDIO muxing configuration relies on the MDIO support provided in the first patch.

2019-08-02arm64: dts: fsl: ls1028a: Enable eth port1 on the ls1028a QDS boardClaudiu Manoil
LS1028a has one Ethernet management interface. On the QDS board, the MDIO signals are multiplexed to either on-board AR8035 PHY device or to 4 PCIe slots allowing for SGMII cards. To enable the Ethernet ENETC Port 1, which can only be connected to a RGMII PHY, the multiplexer needs to be configured to route the MDIO to the AR8035 PHY. The MDIO/MDC routing is controlled by bits 7:4 of FPGA board config register 0x54, and value 0 selects the on-board RGMII PHY. The FPGA board config registers are accessible on the i2c bus, at address 0x66. The PF3 MDIO PCIe integrated endpoint device allows for centralized access to the MDIO bus. Add the corresponding devicetree node and set it to be the MDIO bus parent.

2019-08-02enetc: Add mdio bus driver for the PCIe MDIO endpointClaudiu Manoil
ENETC ports can manage the MDIO bus via local register interface. However there's also a centralized way to manage the MDIO bus, via the MDIO PCIe endpoint device integrated by the same root complex that also integrates the ENETC ports (eth controllers). Depending on board design and use case, centralized access to MDIO may be better than using local ENETC port registers. For instance, on the LS1028A QDS board where MDIO muxing is required. Also, the LS1028A on-chip switch doesn't have a local MDIO register interface. The current patch registers the above PCIe endpoint as a separate MDIO bus and provides a driver for it by re-using the code used for local MDIO access. It also allows the ENETC port PHYs to be managed by this driver if the local "mdio" node is missing from the ENETC port node.

phy-handle is necessary for the AST2600 which separates the MDIO controllers from the MAC. I've tried to minimise the intrusion of supporting the AST2600 to the FTGMAC100 by leaving in place the existing MDIO support for the embedded MDIO interface. The AST2400 and AST2500 continue to be supported this way, as it avoids breaking/reworking existing devicetrees. The AST2600 support by contrast requires the presence of the phy-handle property in the MAC devicetree node to specify the appropriate PHY to associate with the MAC. In the event that someone wants to specify the MDIO bus topology under the MAC node on an AST2400 or AST2500, the current auto-probe approach is done conditional on the absence of an "mdio" child node of the MAC.

The AST2600 design separates the MDIO controllers from the MAC, which is where they were placed in the AST2400 and AST2500. Further, the register interface is reworked again, so now we have three possible different interface implementations, however this driver only supports the interface provided by the AST2600. The AST2400 and AST2500 will continue to be supported by the MDIO support embedded in the FTGMAC100 driver. The hardware supports both C22 and C45 mode, but for the moment only C22 support is implemented.
