It doesn't constitute a device tree binding +specification by itself but is meant to be referenced by platform-specific +device tree bindings. + +When referenced from platform device tree bindings the properties defined in +this document are defined as follows. + +- reg: Memory mapped base address and length of the DWC HDMI RX registers. + +- interrupts: Reference to the DWC HDMI RX interrupt and 5v sense interrupt. + +- snps,hdmi-phy-jtag-addr: JTAG address of the phy to be used. + +- snps,hdmi-phy-version: Version of the phy to be used. + +- snps,hdmi-phy-cfg-clk: Value of the cfg clk that is delivered to phy. + +- snps,hdmi-phy-driver: *Exact* name of the phy driver to be used. + +- snps,hdmi-ctl-cfg-clk: Value of the cfg clk that is delivered to the +controller. + +A sample binding is now provided. The compatible string is for a wrapper driver +which then instantiates the Synopsys Designware HDMI RX decoder driver. + +Example: + +dw_hdmi_wrapper: dw-hdmi-wrapper@0 { + compatible = "snps,dw-hdmi-rx-wrapper"; + reg = <0x0 0x10000>; /* controller regbank */ + interrupts = <1 3>; /* controller interrupt + 5v sense interrupt */ + snps,hdmi-phy-driver = "dw-hdmi-phy-e405"; + snps,hdmi-phy-version = <405>; + snps,hdmi-phy-cfg-clk = <25>; /* MHz */ + snps,hdmi-ctl-cfg-clk = <25>; /* MHz */ + snps,hdmi-phy-jtag-addr = /bits/ 8 <0xfc>; +}; -- 1.9.1 -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
