rK3568-修改RTL8211F-CG网口led显示灯状态

1.修改代码路径

/home/salesdmcf/works/SDK/Linux/kernel/drivers/net/phy/realtek.c

static int phy_rtl8211f_led_fixup(struct phy_device *phydev)
{
u32 val, val2;

printk("lyc-----> in : %s\n", __func__);

/*set led1(green) Link 10/100/1000M, and set led2(yellow) Link 10/100/1000M+Active*/
val = phy_read_paged(phydev, LCR_PAGE_SELECT,RTL_8211F_LCR_ADDR);
val |= (1<<5);
val |= (1<<8);
val &= (~(1<<9));
val |= (1<<10);
val |= (1<<11);
phy_write_paged(phydev, LCR_PAGE_SELECT,RTL_8211F_LCR_ADDR, val);

/*set led1(green) EEE LED function disabled so it can keep on when linked*/
val2 = phy_read_paged(phydev, LCR_PAGE_SELECT,RTL_8211F_EEELCR_ADDR);
val2 &= (~(1<<2));
phy_write_paged(phydev,LCR_PAGE_SELECT, RTL_8211F_EEELCR_ADDR, val2);

return 0;
}
