Qualcomm's USB HS PHY
|
|
PROPERTIES
|
|
- compatible:
|
Usage: required
|
Value type: <string>
|
Definition: Should contain "qcom,usb-hs-phy" and more specifically one of the
|
following:
|
|
"qcom,usb-hs-phy-apq8064"
|
"qcom,usb-hs-phy-msm8916"
|
"qcom,usb-hs-phy-msm8974"
|
|
- #phy-cells:
|
Usage: required
|
Value type: <u32>
|
Definition: Should contain 0
|
|
- clocks:
|
Usage: required
|
Value type: <prop-encoded-array>
|
Definition: Should contain clock specifier for the reference and sleep
|
clocks
|
|
- clock-names:
|
Usage: required
|
Value type: <stringlist>
|
Definition: Should contain "ref" and "sleep" for the reference and sleep
|
clocks respectively
|
|
- resets:
|
Usage: required
|
Value type: <prop-encoded-array>
|
Definition: Should contain the phy and POR resets
|
|
- reset-names:
|
Usage: required
|
Value type: <stringlist>
|
Definition: Should contain "phy" and "por" for the phy and POR resets
|
respectively
|
|
- v3p3-supply:
|
Usage: required
|
Value type: <phandle>
|
Definition: Should contain a reference to the 3.3V supply
|
|
- v1p8-supply:
|
Usage: required
|
Value type: <phandle>
|
Definition: Should contain a reference to the 1.8V supply
|
|
- extcon:
|
Usage: optional
|
Value type: <prop-encoded-array>
|
Definition: Should contain the vbus extcon
|
|
- qcom,init-seq:
|
Usage: optional
|
Value type: <u8 array>
|
Definition: Should contain a sequence of ULPI address and value pairs to
|
program into the ULPI_EXT_VENDOR_SPECIFIC area. This is related
|
to Device Mode Eye Diagram test. The addresses are offsets
|
from the ULPI_EXT_VENDOR_SPECIFIC address, for example,
|
<0x1 0x53> would mean "write the value 0x53 to address 0x81".
