2025-03-19net: phy: ksz90x1: Load skew values from device treePaul Barker
Various signal skew values may be set in the device tree for the ksz9131 Ethernet PHY. For example, the RZ/G2L board requires non-default values for rxc-skew-psec & txc-skew-psec. This is based on the ksz9131 phy driver in Linux v6.11. Reviewed-by: Marek Vasut <[email protected]> Signed-off-by: Paul Barker <[email protected]>
2025-03-19net: phy: ksz90x1: Handle ksz9131 LED errataPaul Barker
Micrel KSZ9131 PHY LED behavior is not correct when configured in Individual Mode, LED1 (Activity LED) is in the ON state when there is no-link. Workaround this by setting bit 9 of register 0x1e after verifying that the LED configuration is Individual Mode. This issue is described in KSZ9131RNX Silicon Errata DS80000693B [*] and according to that it will not be corrected in a future silicon revision.

2025-01-30net: phy: Add RGMII RX/TX delay handling to DP83822 PHYMarek Vasut
The TI DP83822 does have support for configurable RGMII RX/TX clock shift, add support for parsing DT properties which describe the RX/TX clock shift configuration and configuration of the matching bits in RCSR register. The shift is only configurable on DP83822, the other PHYs supported by this PHY driver, namely DP83825/DP83826 variants, do not implement this functionality and the RCSR bits used to configure the clock shift are missing from those PHYs. The shift is configurable separately for RX and TX path. Each path can either enable the shift or disable the shift using single bit. In case the shift is disabled, a delay of 0ns is added to the path, otherwise a delay of 3.5ns is added to the path. Note that the two RCSR bits 11 and 12 have inverted logic, RCSR bit 12 enables RX internal shift when SET, while RCSR bit 11 enables TX shift when UNSET.

2025-01-01Revert "net: phy: marvell 88e151x: Fix handling of bare RGMII interface type"Rufus Segar
This reverts commit 431be621c6cbc72efd1d45fa36686a682cbb470a. Section 3.3 of Reduced Gigabit Media Independent Interface (RGMII) Version 2.0 (4/1/2002) details that a PHYs using a ~2ns internal delay are referred to as RGMII-ID. This internal delay is optional. Page 147-148 of the Marvell Doc. No. MV-S107146-U0 Rev. F details timings of the RX/TX delays. We see that with the TX/RX_CLK delay enabled, our RX/TX_CTL signal is shifted w.r.t CLK to reflect the delay added. In 431be62 there is no timing difference between RGMII and RGMII-ID, and so programmers wanting to explicitly set their PHY to RGMII will find that delay added anyway. This could throw off timing if that internal delay is undesired. We should be handling all 4 possible RGMII cases of PHY_INTERFACE_MODE: RGMII, RGMII_ID, RGMII_TXID, and RGMII_RXID. Reverting 431be62 implements this. See also m88e1111_config_init_rgmii_delays in the equivalent driver in Linux (drivers/net/phy/marvell.c), which does not set these delays in RGMII mode. 68e6eca was tested out on an 88E1512 PHY in RGMII-ID mode. This reversion has been tested by myself on an 88E1518 in RGMII-ID mode. This patch affects boards using this driver in "rgmii" mode, as the internal delay will no longer be enabled. Namely kikwood-nsa310s. Signed-off-by: Rufus Segar <[email protected]>

2024-10-16net: introduce alternative implementation as net/lwip/Jerome Forissier
Prepare the introduction of the lwIP (lightweight IP) TCP/IP stack by adding a new net/lwip/ directory and the NET_LWIP symbol. Network support is either NO_NET, NET (legacy stack) or NET_LWIP. Subsequent commits will introduce the lwIP code, re-work the NETDEVICE integration and port some of the NET commands and features to lwIP. SPL_NET cannot be enabled when NET_LWIP=y. SPL_NET pulls some symbols that are part of NET (such as arp_init(), arp_timeout_check(), arp_receive(), net_arp_wait_packet_ip()). lwIP support in SPL may be added later. Similarly, DFU_TFTP and FASTBOOT are not compatible with NET_LWIP because of dependencies on net_loop(), tftp_timeout_ms, tftp_timeout_count_max and other NET things. Let's add a dependency on !NET_LWIP for now. SANDBOX can select NET_LWIP but doing so will currently disable the eth dm tests as well as the wget tests which have strong dependencies on the NET code. Other adjustments to Kconfig files are made to fix "unmet direct dependencies detected" for USB_FUNCTION_SDP and CMD_FASTBOOT when the default networking stack is set to NET_LWIP ("default NET_LWIP" instead of "default NET" in Kconfig). The networking stack is now a choice between NO_NET, NET and NET_LWIP. Therefore '# CONFIG_NET is not set' should be 'CONFIG_NO_NET=y'. Adjust the defconfigs accordingly.

Setting the clock delay from the device tree settings rx-internal-delay-ps and tx-internal-delay-ps was broken: - The expected value in the device tree is suppose to be a delay in picoseconds, but the driver only allowed an array index. - Driver converted this array index to the actual delay in picoseconds and tried to apply this in the device register. This however is not a valid register value. The actual logic here was reversed, it converted an register representation of the delay to the device tree delay in picoseconds.
