Subject: [PATCH v2 1/4] dt-bindings: usb: musb: Add support for MediaTek musb controller
Date: Tue, 15 Jan 2019 09:43:43 +0800	[thread overview]
Message-ID: <1547516626-5084-2-git-send-email-min.guo@mediatek.com> (raw)
In-Reply-To: <1547516626-5084-1-git-send-email-min.guo@mediatek.com>

From: Min Guo <min.guo@mediatek.com>

+MediaTek musb DRD/OTG controller
+-------------------------------------------
+
+Required properties:
+ - compatible      : should be "mediatek,mtk-musb"
+ - reg             : specifies physical base address and size of
+   the registers
+ - interrupts      : interrupt used by musb controller
+ - interrupt-names : must be "mc"
+ - phys            : PHY specifier for the OTG phy
+ - dr_mode         : should be one of "host", "peripheral" or "otg",
+   refer to usb/generic.txt
+ - clocks          : a list of phandle + clock-specifier pairs, one for
+   each entry in clock-names
+ - clock-names     : must contain "main", "mcu", "univpll"
+   for clocks of controller
+
+Optional properties:
+ - extcon : external connector for VBUS and IDPIN changes detection,
+   needed when supports dual-role mode.
+ - vbus-supply : reference to the VBUS regulator, needed when supports
+   dual-role mode.
+ - power-domains   : a phandle to USB power domain node to control USB's
+   MTCMOS
+
+Example:
+
+usb2: usb@11200000 {
+	compatible = "mediatek,mt2701-musb",
+		     "mediatek,mtk-musb";
+	reg = <0 0x11200000 0 0x1000>;
+	interrupts = <GIC_SPI 32 IRQ_TYPE_LEVEL_LOW>;
+	interrupt-names = "mc";
+	phys = <&u2port2 PHY_TYPE_USB2>;
+	vbus-supply = <&usb_vbus>;
+	extcon = <&extcon_usb>;
+	dr_mode = "otg";
+	clocks = <&pericfg CLK_PERI_USB0>,
+		 <&pericfg CLK_PERI_USB0_MCU>,
+		 <&pericfg CLK_PERI_USB_SLV>;
+	clock-names = "main","mcu","univpll";
+	power-domains = <&scpsys MT2701_POWER_DOMAIN_IFR_MSC>;
+};
