Qualcomm Technologies, Inc. eUSB2 SNPS USB HSPHY
|
||
|
|
|
||
|
|
Required properties:
|
||
|
|
- compatible: Should be "qcom,usb-snps-eusb2-phy"
|
||
|
|
- reg: Address and length of the register set for the device
|
||
|
|
Required regs are:
|
||
|
|
"eusb2_phy_base" : the base register for the PHY
|
||
|
|
"eud_detect_reg" : VIOCTL_EUD_DETECT register
|
||
|
|
|
||
|
|
- <supply-name>-supply: phandle to the regulator device tree node
|
||
|
|
Required "supply-name" examples are:
|
||
|
|
"vdd" : vdd supply for HSPHY digital circuit operation
|
||
|
|
"vdda12" : 1.2v supply for HSPHY
|
||
|
|
- clocks: a list of phandles to the PHY clocks. Use as per
|
||
|
|
Documentation/devicetree/bindings/clock/clock-bindings.txt
|
||
|
|
- clock-names: Names of the clocks in 1-1 correspondence with the "clocks"
|
||
|
|
property. "ref_clk_src" is a mandatory clock.
|
||
|
|
- qcom,vdd-voltage-level: This property must be a list of three integer
|
||
|
|
values (no, min, max) where each value represents either a voltage in
|
||
|
|
microvolts or a value corresponding to voltage corner
|
||
|
|
- resets: reset specifier pair consists of phandle for the reset controller
|
||
|
|
and reset lines used by this controller.
|
||
|
|
- reset-names: reset signal name strings sorted in the same order as the resets
|
||
|
|
property.
|
||
|
|
- usb-repeater: phandle to eUSB2 repeater which is used with eUSB2 HSPHY for USB
|
||
|
|
functionality.
|
||
|
|
|
||
|
|
Optional properties:
|
||
|
|
- qcom,param-override-seq: parameter override sequence with value, reg offset
|
||
|
|
pair.
|
||
|
|
- reg: Address and length of the register set for the device
|
||
|
|
Optional regs are:
|
||
|
|
"eud_enable_reg" : register address to read eud enable/disable status.
|
||
|
|
- dummy-supply: phandle to eUSB2 repeater for enforcing probe ordering for
|
||
|
|
eUSB2 repeater and eUSB2 PHY driver.
|
||
|
|
|
||
|
|

vdda12-supply = <&pm8941_l6>;
|
||
|
|
qcom,vdd-voltage-level = <0 880000 880000>;
|
||
|
|
qcom,param-override-seq = <0x43 0x70>;
|
||
|
|
usb-repeater= <&pm8550b_eusb2_repeater>;
