I'll add mtk_phy_led_num_dly_cfg() in mtk-phy-lib.c like this:

int mtk_phy_led_num_dly_cfg(u8 index, unsigned long *delay_on,
			    unsigned long *delay_off, bool *blinking)
{
	if (index > 1)
		return -EINVAL;

	if (delay_on && delay_off && (*delay_on > 0) && (*delay_off >
0)) {
		*blinking = true;
		*delay_on = 50;
		*delay_off = 50;
	}

	return 0;
}
EXPORT_SYMBOL_GPL(mtk_phy_led_num_dly_cfg);

Also fix *_phy_led_blink_set() in mtk-ge.c/mtk-ge-soc.c/mtk-2p5ge.c
like this:

static int mt798x_phy_led_blink_set(struct phy_device *phydev, u8
index,
				    unsigned long *delay_on,
				    unsigned long *delay_off)
{
	struct mtk_socphy_priv *priv = phydev->priv;
	bool blinking = false;
	int err = 0;

	err = mtk_phy_led_num_dly_cfg(index, delay_on, delay_off,
&blinking);
	if (err < 0)
		return err;

	err = mtk_phy_hw_led_blink_set(phydev, index, &priv->led_state,
				       blinking);
	if (err)
		return err;

	return mtk_phy_hw_led_on_set(phydev, index, &priv->led_state,
				     MTK_GPHY_LED_ON_MASK, false);
}

BRs,
