From 3699f119ff8da021fe7a1759e98e38ca88fa6766 Mon Sep 17 00:00:00 2001 From: Hans Ulli Kroll Date: Wed, 8 Feb 2017 21:00:09 +0100 Subject: [PATCH 27/31] usb: host: add DT bindings for faraday fotg2 This adds device tree bindings for the Faraday FOTG2 dual-mode host controller. Cc: devicetree@vger.kernel.org Signed-off-by: Hans Ulli Kroll Signed-off-by: Linus Walleij --- ChangeLog v1->v3: - Change compatible to "faraday,fotg210" as the name of the hardware block. - Add an elaborate SoC-specific compatible string for the Cortina Systems Gemini so that SoC-specific features can be enabled. - Add cortina,gemini-mini-b to indicate a Gemini PHY with a Mini-B adapter connected. - Indicated that the Gemini version can handle "wakeup-source". - Add optional IP block clock. --- .../devicetree/bindings/usb/faraday,fotg210.txt | 35 ++++++++++++++++++++++ 1 file changed, 35 insertions(+) create mode 100644 Documentation/devicetree/bindings/usb/faraday,fotg210.txt --- /dev/null +++ b/Documentation/devicetree/bindings/usb/faraday,fotg210.txt @@ -0,0 +1,35 @@ +Faraday FOTG Host controller + +This OTG-capable USB host controller is found in Cortina Systems +Gemini and other SoC products. + +Required properties: +- compatible: should be one of: + "faraday,fotg210" + "cortina,gemini-usb", "faraday,fotg210" +- reg: should contain one register range i.e. start and length +- interrupts: description of the interrupt line + +Optional properties: +- clocks: should contain the IP block clock +- clock-names: should be "PCLK" for the IP block clock + +Required properties for "cortina,gemini-usb" compatible: +- syscon: a phandle to the system controller to access PHY registers + +Optional properties for "cortina,gemini-usb" compatible: +- cortina,gemini-mini-b: boolean property that indicates that a Mini-B + OTH connector is in use +- wakeup-source: see power/wakeup-source.txt + +Example for Gemini: + +usb@68000000 { + compatible = "cortina,gemini-usb", "faraday,fotg210"; + reg = <0x68000000 0x1000>; + interrupts = <10 IRQ_TYPE_LEVEL_HIGH>; + clocks = <&cc 12>; + clock-names = "PCLK"; + syscon = <&syscon>; + wakeup-source; +};
