54 vdda33-supply:
57 qcom,hs-disconnect-bp:
61 The hardware accepts only discrete values. The value closest to the
62 provided input will be chosen as the override value for this param.
63 minimum: -272
66 qcom,squelch-detector-bp:
69 detect valid high-speed data.
70 The hardware accepts only discrete values. The value closest to the
71 provided input will be chosen as the override value for this param.
72 minimum: -2090
75 qcom,hs-amplitude-bp:
77 This adjusts the high-speed DC level voltage.
78 The hardware accepts only discrete values. The value closest to the
79 provided input will be chosen as the override value for this param.
80 minimum: -660
83 qcom,pre-emphasis-duration-bp:
86 HS pre-emphasis current is sourced onto DP<#> or DM<#>.
87 The HS Transmitter pre-emphasis duration is defined in terms of
88 unit amounts. One unit of pre-emphasis duration is approximately
89 650 ps and is defined as 1X pre-emphasis duration.
90 The hardware accepts only discrete values. The value closest to the
91 provided input will be chosen as the override value for this param.
95 qcom,pre-emphasis-amplitude-bp:
98 DP<#> and DM<#> after a J-to-K or K-to-J transition.
99 The HS Transmitter pre-emphasis current is defined in terms of unit
101 1X pre-emphasis current.
102 The hardware accepts only discrete values. The value closest to the
103 provided input will be chosen as the override value for this param.
107 qcom,hs-rise-fall-time-bp:
109 This adjusts the rise/fall times of the high-speed waveform.
110 The hardware accepts only discrete values. The value closest to the
111 provided input will be chosen as the override value for this param.
112 minimum: -4100
115 qcom,hs-crossover-voltage-microvolt:
119 The hardware accepts only discrete values. The value closest to the
120 provided input will be chosen as the override value for this param.
121 minimum: -31000
124 qcom,hs-output-impedance-micro-ohms:
127 on the D+ and D- paths between the transceiver and cable. This adjusts
129 resistance on the USB. The hardware accepts only discrete values. The
130 value closest to the provided input will be chosen as the override value
132 minimum: -2300000
135 qcom,ls-fs-output-impedance-bp:
137 This adjusts the low- and full-speed single-ended source
140 The hardware accepts only discrete values. The value closest to the
141 provided input will be chosen as the override value for this param.
142 minimum: -1053
