6a10bc5be8 net: phy: realtek: Use generic genphy_parse_link() for RTL8211E
The problem with current implementation is that SPDDONE bit is 1
but link bit is zero. That's why phydev->link is setup to 0
which ending up in driver failure that link is not up.

Log:
Zynq> dhcp
ethernet@e000b000 Waiting for PHY auto negotiation to complete.......
done
ethernet@e000b000: No link.

There is at least 1ms delay between spddone bit and link up.

Use genphy_read_status() instead of realtek implemenation which is
working with page 11. Linux driver is also using generic implementation.

793ea94770 net/phy: refactor RTL8211F initialization
RTL8211F needs to enalbe TXDLY for RGMII during
phy initialization, so move it to rtl8211f_config
for early initialization.

3d6af748eb net/phy: Add support for realtek RTL8211F
RTL8211F has different registers from RTL8211E.
This patch adds support for RTL8211F PHY which
can be found on Freescale's T1023 RDB board.

3cee138892 net: phy: realtek: Disable interrupt on Realtek Ethernet PHY drivers
Some Realtek Ethernet PHYs, like RTL8211D(G/N) and RTL8211E(G), have
interrupts enabled by default. If the interrupt is not treated later by
the OS and the PHY's interrupt line is enabled and shared with other
interrupts, the system will get an interrupt storm. This patch disables
the interrupt for PHY devices that use one of the current Realtek
Ethernet PHY drivers. Some of Realtek Ethernet PHYs, such as RTL8211B(L)
have the interrupt masked. In this case, the functionality of the PHY
should not be afected since this patch brings INER and INSR registers to
their default values.

4220504767 net/phy: realtek: Fix the PHY ID mask to ensure the correct Realtek PHY is detected
The 'get_phy_driver' code in 'drivers/net/phy/phy.c' uses the following
method to determine which driver is to be loaded for a particular PHY
module:

list_for_each(entry, &phy_drivers) {
	drv = list_entry(entry, struct phy_driver, list);
	if ((drv->uid & drv->mask) == (phy_id & drv->mask))
		return drv;
}

This means that a drv->mask of 0xfffff0 will return incorrect phy driver
for the logic above, even if the drv->uid is anything other than
something ending with a 0x0.

For e.g. if the RTL8211E drv->uid is 0x1cc915 and drv->mask is 0xffffff
and the RTL8211B drv->uid is 0x1cc910 and drv->mask is 0xffffff0, then
the phy driver selected will always be RTL8211B even though the
underlying phy connected on the board is a 8211E module.

This patch fixes this issue.

c624d168bf net: phy/realtek: Add support for RTL8211DN and RTL8211E phy modules
This patch adds support for Realtek PHY modules RTL8211DN and
RTL8211E (variants: RTL8211E-VB-CG, RTL8211E-VL-CG, RTL8211EG-VB-CG),
which can be found on Freescale's T1040RDB boards.

To make the driver more generic across 8211 family, a generic name 8211x
is added for macros and function names.

9082eeac5d phylib: Add a bunch of PHY drivers from tsec
The tsec driver had a bunch of PHY drivers already written. This
converts them all into PHY Lib drivers, and serves as the first
set of PHY drivers for PHY Lib.

While doing that, cleaned up a number of magic numbers (though
not all of them, as PHY vendors like to keep their numbers as
magical as possible).  Also, noticed that almost all of the
vitesse/cicada PHYs had the same config/parse/startup functions,
so those have been collapsed into one.
