From 7e0b4cd06201ee9dbdf2d13bfd7b8a021b414e42 Mon Sep 17 00:00:00 2001 From: Dinh Nguyen Date: Thu, 6 Feb 2014 16:48:43 -0600 Subject: dts: socfpga: Add DTS entry for adding the stmmac glue layer for stmmac. This patch adds the dts bindings documenation for the Altera SOCFPGA glue layer for the Synopsys STMMAC ethernet driver. Signed-off-by: Dinh Nguyen Acked-by: David S. Miller --- v3: Remove stray empty line at end of socfpga_cyclone5_socdk.dts v2: Use the dwmac-sti as an example for a glue layer and split patch up to have dts as a separate patch. Also cc dts maintainers since there is a new binding. --- .../devicetree/bindings/net/socfpga-dwmac.txt | 35 ++++++++++++++++ arch/arm/boot/dts/socfpga.dtsi | 49 +++++++++++++++------- arch/arm/boot/dts/socfpga_arria5_socdk.dts | 24 +++++++++++ arch/arm/boot/dts/socfpga_cyclone5_socdk.dts | 17 ++++++++ arch/arm/boot/dts/socfpga_cyclone5_sockit.dts | 22 +++++++++- arch/arm/boot/dts/socfpga_vt.dts | 8 ++++ 6 files changed, 138 insertions(+), 17 deletions(-) create mode 100644 Documentation/devicetree/bindings/net/socfpga-dwmac.txt diff --git a/Documentation/devicetree/bindings/net/socfpga-dwmac.txt b/Documentation/devicetree/bindings/net/socfpga-dwmac.txt new file mode 100644 index 0000000..d53d376 --- /dev/null +++ b/Documentation/devicetree/bindings/net/socfpga-dwmac.txt @@ -0,0 +1,35 @@ +Altera SOCFPGA SoC DWMAC controller + +The device node has following properties. + +Required properties: + - compatible : Should contain "altr,socfpga-stmmac" + - altr,sysmgr-syscon : Should be the phandle to the system manager node that + encompasses the glue register, and the register offset. + +Sub-nodes: +The dwmac core should be added as subnode to SOCFPGA dwmac glue. +- dwmac : The binding details of dwmac can be found in + Documentation/devicetree/bindings/net/stmmac.txt + +Example: + +ethernet0: ethernet0 { + #address-cells = <1>;
