net: phy: realtek: use LEDCR page number define on RTL8211F

2026-04-13T23:38:25Z

Replace the magic number with an existing define for the LEDCR register page number on the RTL8211F. Signed-off-by: Aleksander Jan Bajkowski Reviewed-by: Daniel Golle Link: https://patch.msgid.link/20260411105150.184577-1-olek2@wp.pl Signed-off-by: Jakub Kicinski

net: phy: realtek: convert RTL8211F to .disable_autonomous_eee

2026-04-12T18:33:23Z

The RTL8211F previously unconditionally disabled PHY-mode EEE in config_init. Convert this to use the new .disable_autonomous_eee callback so it is only disabled when the MAC indicates EEE support via phy_support_eee(). This preserves PHY-autonomous EEE for MACs that do not support EEE, while still disabling it when the MAC manages LPI.

net: phy: realtek: Add property to enable SSC

2026-04-10T03:01:52Z

Add support for spread spectrum clocking (SSC) on RTL8211F(D)(I)-CG, RTL8211FS(I)(-VS)-CG, RTL8211FG(I)(-VS)-CG PHYs. The implementation follows EMI improvement application note Rev. 1.2 for these PHYs. The current implementation enables SSC for both RXC and SYSCLK clock signals. Introduce DT properties 'realtek,clkout-ssc-enable', 'realtek,rxc-ssc-enable' and 'realtek,sysclk-ssc-enable' which control CLKOUT, RXC and SYSCLK SSC spread spectrum clocking enablement on these signals.

net: phy: realtek: get rid of magic numbers in rtl8201_config_intr()

2026-04-09T02:17:17Z

Replace the magic numbers with defines. Register names were obtained from publicly available documentation[1]. This should make it clear what's going on in the code. 1.

net: phy: realtek: add RTL8224 polarity support

2026-03-21T02:12:46Z

The RTL8224 has a register to configure the polarity of every pair of each port. It provides device designers more flexbility when wiring the chip. Unfortunately, the register is left in an unknown state after a reset. Thus on devices where the bootloader don't initialize it, the driver has to do it to detect and use a link. The MDI polarity swap can be set in the device tree using the property enet-phy-pair-polarity. The u32 value is a bitfield where bit[0..3] control the polarity of pairs A..D.

net: phy: realtek: add RTL8224 pair order support

2026-03-21T02:12:46Z

The RTL8224 has a register to configure a pair swap (from ABCD order to DCBA) providing PCB designers more flexbility when wiring the chip. The swap parameter has to be set correctly for each of the 4 ports before the chip can detect a link. After a reset, this register is (unfortunately) left in a random state, thus it has to be initialized. On most of the devices the bootloader does it once for all and we can rely on the value set, on some other it is not and the kernel has to do it. The MDI pair swap can be set in the device tree using the property enet-phy-pair-order. The property is set to 0 to keep the default order (ABCD), or 1 to reverse the pairs (DCBA).

Realtek RTL8211F-VD has the same LED configuration and registers as RTL8211F. Use the existing LED related functions for this chip, so it is possible to also use the netdev trigger.

net: phy: realtek: simplify bogus paged operations

2026-01-18T00:12:16Z

Only registers 0x10~0x17 are affected by the value in the page selection register 0x1f. Hence there is no point in using paged operations when accessing any other registers. Simplify the driver by using the normal phy_read and phy_write operations for registers which are anyway not affected by paging.

net: phy: realtek: demystify PHYSR register location

2026-01-18T00:12:16Z

Turns out that register address RTL_VND2_PHYSR (0xa434) maps to Clause-22 register MII_RESV2. Use that to get rid of yet another magic number, and rename access macros accordingly.

net: phy: realtek: reunify C22 and C45 drivers

2026-01-18T00:12:16Z

Reunify the split C22/C45 drivers for the RTL8221B-VB-CG 2.5Gbps and RTL8221B-VM-CG 2.5Gbps PHYs back into a single driver. This is possible now by using all the driver operations previously used by the C45 driver, as transparent access to all MMDs including MDIO_MMD_VEND2 is now possible also over Clause-22 MDIO. The unified driver will still only use Clause-45 access on any Clause-45 capable busses while still working fine on Clause-22 busses.
