STMicroelectronics SoC DWMAC glue layer controller
+This file documents differences between the core properties in
+Documentation/devicetree/bindings/net/stmmac.txt
+and what is needed on STi platforms to program the stmmac glue logic.
+
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
+ - compatible : Can be "st,stih415-dwmac", "st,stih416-dwmac",
+ "st,stih407-dwmac", "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
+ - st,syscon : Should be phandle to system configuration node which
encompases this glue registers.
+ - st,gmac_en: this is to enable the gmac into a dedicated sysctl control
+ register available on STiH407 SoC.
+ - sti-ethconf: this is the gmac glue logic register to enable the GMAC,
+ select among the different modes and program the clk retiming.
+ - pinctrl-0: pin-control for all the MII mode supported.
- - 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.
-
+Optional properties:
+ - resets : phandle pointing to the system reset controller with correct
+ reset line index for ethernet reset.
+ - st,ext-phyclk: valid only for RMII where PHY can generate 50MHz clock or
+ MAC can generate it.
+ - st,tx-retime-src: This specifies which clk is wired up to the mac for
+ retimeing tx lines. This is totally board dependent and can take one of the
+ posssible values from "txclk", "clk_125" or "clkgen".
+ If not passed, the internal clock will be used by default.
+ - sti-ethclk: this is the phy clock.
+ - sti-clkconf: this is an extra sysconfig register, available in new SoCs,
+ to program the clk retiming.
+ - st,gmac_en: to enable the GMAC, this only is present in some SoCs; e.g.
+ STiH407.
