+The device node has following properties.
+
+Required properties:
+ - compatible	: Can be "st,stih415-dwmac", "st,stih416-dwmac" or
+   "st,stid127-dwmac".
+ - reg		: Offset of the glue configuration register map in system
+   configuration regmap pointed by st,syscon property and size.
+
+ - reg-names	: Should be "sti-ethconf".
+
+ - st,syscon	: Should be phandle to system configuration node which
+   encompases this glue registers.
+
+ - st,tx-retime-src: On STi Parts for Giga bit speeds, 125Mhz clocks can be
+   wired up in from different sources. One via TXCLK pin and other via CLK_125
+   pin. This wiring is totally board dependent. However the retiming glue
+   logic should be configured accordingly. Possible values for this property
+
+	   "txclk" - if 125Mhz clock is wired up via txclk line.
+	   "clk_125" - if 125Mhz clock is wired up via clk_125 line.
+
+   This property is only valid for Giga bit setup( GMII, RGMII), and it is
+   un-used for non-giga bit (MII and RMII) setups. Also note that internal
+   clockgen can not generate stable 125Mhz clock.
+
+ - st,ext-phyclk: This boolean property indicates who is generating the clock
+  for tx and rx. This property is only valid for RMII case where the clock can
+  be generated from the MAC or PHY.
+
+ - clock-names: should be "sti-ethclk".
+ - clocks: Should point to ethernet clockgen which can generate phyclk.
+

-The 3Com Etherlink Plus (3c505) driver.
-
-This driver now uses DMA.  There is currently no support for PIO operation.
-The default DMA channel is 6; this is _not_ autoprobed, so you must
-make sure you configure it correctly.  If loading the driver as a
-module, you can do this with "modprobe 3c505 dma=n".  If the driver is
-linked statically into the kernel, you must either use an "ether="
-statement on the command line, or change the definition of ELP_DMA in 3c505.h.
-
-The driver will warn you if it has to fall back on the compiled in
-default DMA channel. 
-
-If no base address is given at boot time, the driver will autoprobe
-ports 0x300, 0x280 and 0x310 (in that order).  If no IRQ is given, the driver
-will try to probe for it.
-
-The driver can be used as a loadable module.
-
-Theoretically, one instance of the driver can now run multiple cards,
-in the standard way (when loading a module, say "modprobe 3c505
-io=0x300,0x340 irq=10,11 dma=6,7" or whatever).  I have not tested
-this, though.
-
-The driver may now support revision 2 hardware; the dependency on
-being able to read the host control register has been removed.  This
-is also untested, since I don't have a suitable card.
-
-Known problems:
- I still see "DMA upload timed out" messages from time to time.  These
-seem to be fairly non-fatal though.
- The card is old and slow.
-
-To do:
- Improve probe/setup code
- Test multicast and promiscuous operation
-
-Authors:
- The driver is mainly written by Craig Southeren, email
- <craigs@ineluki.apana.org.au>.
- Parts of the driver (adapting the driver to 1.1.4+ kernels,
- IRQ/address detection, some changes) and this README by
- Juha Laiho <jlaiho@ichaos.nullnet.fi>.
- DMA mode, more fixes, etc, by Philip Blundell <pjb27@cam.ac.uk>
- Multicard support, Software configurable DMA, etc., by
