From f9cfc45c57227448d4239e9582258587aacf34e7 Mon Sep 17 00:00:00 2001 From: Hans Ulli Kroll Date: Wed, 8 Feb 2017 21:00:09 +0100 Subject: [PATCH 14/18] 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 Acked-by: Rob Herring Signed-off-by: Linus Walleij --- ChangeLog v1->v2: - Changed "OTH" to "OTG" - Collected Rob's ACK. - I don't see any problem with these bindings, but IIRC Hans had some reservations for the OTG mode, maybe we can strip some properties like the mini-usb thing and use as a starter so we can add host mode at least? --- .../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 + OTG 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; +};
