net: phy: mscc: add support for the VSC8572

2026-05-06T09:07:22Z

This is similar to the VSC8574 according to the Linux commit that adds support for it [1]. This was tested on an HX1000 board with SGMII (PIC64-HX SoC which has a GEM MAC).

net: phy: mscc: Enable RMII clock output for VSC8541 PHY

2026-02-11T08:41:26Z

Set RMII reference clock output to enabled (1) by default for VSC8541 PHY in RMII mode. The RMII specification requires a 50MHz reference clock, and many board designs expect the PHY to provide this clock to the MAC controller. Previously, the driver defaulted rmii_clk_out to 0 (disabled) for all interface modes, which caused the PHY to not output the required 50MHz clock. This resulted in MAC-PHY communication failures and prevented network operations like DHCP from working on RMII-configured boards. This change alligns with the hardware power-up default behavior and aligns with both the generic PHY driver and Linux MSCC PHY driver implementations.

net: phy: mscc: add support for VSC8502 in dual RGMII mode

2021-11-23T07:57:55Z

The VSC8502 is a Microchip (formerly Microsemi, formerly Vitesse) dual port, gigabit Ethernet copper PHY which supports the MII, GMII and RGMII MAC-side interfaces. Of these, I could only test RGMII, and my board needed RGMII delays to be applied by software, so I am able to confirm that this patch handles that properly.

net: phy: mscc: sync rx/tx delay settings with Linux on vsc85xx

2020-09-30T20:48:18Z

The Linux kernel does set the clock delays to - 0.2 ns (their default, and lowest, hardware value) if delays should not be enabled - 2.0 ns (which causes the data to be sampled at exactly half way between clock transitions at 1000 Mbps) if delays should be enabled depending on the interface mode See https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/drivers/net/phy/mscc/mscc_main.c#n523 So instead of using arbitrary delay values like now, mimic this behaviour. The behaviour is the same for all of vsc8530/8531/8540/8541 so move that to a shared function while at it. Signed-off-by: Heiko Stuebner Reviewed-by: Philipp Tomsich

net: phy: mscc: make clock-output configurable on vsc85xx

2020-09-30T20:48:18Z

The vsc8530/8531/8540/8541 phys have a configurable clock output that can emit 25, 50 and 125 MHz rates, which in turn may be needed for stable network connections.
