Combine the ChipIdea USB binding into a single document to reduce duplication and fragmentation. This marks use of the old PHY bindings as deprecated. Future compatible bindings should use generic PHY binding. Signed-off-by: Rob Herring <robh@kernel.org> Cc: Ivan T.

* USB2 ChipIdea USB controller for ci13xxx
|
|
|
|
Required properties:
|
|
- compatible: should be one of:
|
|
"fsl,imx27-usb"
|
|
"lsi,zevio-usb"
|
|
"qcom,ci-hdrc"
|
|
"chipidea,usb2"
|
|
- reg: base address and length of the registers
|
|
- interrupts: interrupt for the USB controller
|
|
|
|
Recommended properies:
|
|
- phy_type: the type of the phy connected to the core. Should be one
|
|
of "utmi", "utmi_wide", "ulpi", "serial" or "hsic". Without this
|
|
property the PORTSC register won't be touched.
|
|
- dr_mode: One of "host", "peripheral" or "otg". Defaults to "otg"
|
|
|
|
Deprecated properties:
|
|
- usb-phy: phandle for the PHY device. Use "phys" instead.
|
|
- fsl,usbphy: phandle of usb phy that connects to the port. Use "phys" instead.
|
|
|
|
Optional properties:
|
|
- clocks: reference to the USB clock
|
|
- phys: reference to the USB PHY
|
|
- phy-names: should be "usb-phy"
|
|
- vbus-supply: reference to the VBUS regulator
|
|
- maximum-speed: limit the maximum connection speed to "full-speed".
|
|
- tpl-support: TPL (Targeted Peripheral List) feature for targeted hosts
|
|
- fsl,usbmisc: (FSL only) phandler of non-core register device, with one
|
|
argument that indicate usb controller index
|
|
- disable-over-current: (FSL only) disable over current detect
|
|
- external-vbus-divider: (FSL only) enables off-chip resistor divider for Vbus
|
|
|
|
Example:
|
|
|
|
usb@f7ed0000 {
|
|
compatible = "chipidea,usb2";
|
|
reg = <0xf7ed0000 0x10000>;
|
|
interrupts = <GIC_SPI 11 IRQ_TYPE_LEVEL_HIGH>;
|
|
clocks = <&chip CLKID_USB0>;
|
|
phys = <&usb_phy0>;
|
|
phy-names = "usb-phy";
|
|
vbus-supply = <®_usb0_vbus>;
|
|
};
