AM1808 based board, kernel 3.17.0, no Micrel phy link

Dear Gentlemen,

fighting to have eth0 interface up and running with this last recent kernel 3.17.0. I am not using actually DT to configure emac, but the old way.

.

static int __init ipam390_config_emac(void)
{
	void __iomem *cfg_chip3_base;
	int ret;
	u32 val;
	struct davinci_soc_info *soc_info = &davinci_soc_info;
	u8 rmii_en = soc_info->emac_pdata->rmii_en;

	cfg_chip3_base = DA8XX_SYSCFG0_VIRT(DA8XX_CFGCHIP3_REG);

	val = __raw_readl(cfg_chip3_base);

	if (rmii_en) {
		val |= BIT(8);
		ret = davinci_cfg_reg_list(ipam390_rmii_pins);
		pr_info("EMAC: RMII PHY configured, MII PHY will not be"
							" functional\n");
	} else {
		val &= ~BIT(8);
		ret = davinci_cfg_reg_list(ipam390_mii_pins);
		pr_info("EMAC: MII PHY configured, RMII PHY will not be"
							" functional\n");
	}

	if (ret)
		pr_warning("da850_evm_init: cpgmac/rmii mux setup failed: %d\n",
				ret);

	/* configure the CFGCHIP3 register for RMII or MII */
	__raw_writel(val, cfg_chip3_base);
	soc_info->emac_pdata->phy_id = DA850_EVM_PHY_ID;

	ret = da8xx_register_emac();
	if (ret)
		pr_warning("da850_evm_init: emac registration failed: %d\n",
				ret);
	return 0;
}
device_initcall(ipam390_config_emac);

Actually, what i get is :

Kernel 3.17.0
net eth0: attached PHY driver [Micrel KSZ8031] (mii_bus:phy_addr=davinci_mdio-0:00, id=221556)

But my micrel hw is KSZ8051 (first strange thing).

I see phy leds up (both lights up) until the first "Sending discover..." message, then both leds die.

My system have: ARM AM1808 (OMAP-L138),
- davinci-emac.c
- RMII and MDIO to interface to Micrel KSZ8051
- sourcinf 50MHZ clock from emac RMII

Note: if i take the kernel 3.5.1 micrel.c and replace it to the current, phy link works, but no packets are sent out, as if there is no correct link from emac to phyThere is a TX value, but nothing is really sent.

Every help is appreciated.
