60 vdda33-supply:
63 qcom,hs-disconnect-bp:
67 The hardware accepts only discrete values. The value closest to the
68 provided input will be chosen as the override value for this param.
69 minimum: -272
72 qcom,squelch-detector-bp:
75 detect valid high-speed data.
76 The hardware accepts only discrete values. The value closest to the
77 provided input will be chosen as the override value for this param.
78 minimum: -2090
81 qcom,hs-amplitude-bp:
83 This adjusts the high-speed DC level voltage.
84 The hardware accepts only discrete values. The value closest to the
85 provided input will be chosen as the override value for this param.
86 minimum: -660
89 qcom,pre-emphasis-duration-bp:
92 HS pre-emphasis current is sourced onto DP<#> or DM<#>.
93 The HS Transmitter pre-emphasis duration is defined in terms of
94 unit amounts. One unit of pre-emphasis duration is approximately
95 650 ps and is defined as 1X pre-emphasis duration.
96 The hardware accepts only discrete values. The value closest to the
97 provided input will be chosen as the override value for this param.
101 qcom,pre-emphasis-amplitude-bp:
104 DP<#> and DM<#> after a J-to-K or K-to-J transition.
105 The HS Transmitter pre-emphasis current is defined in terms of unit
107 1X pre-emphasis current.
108 The hardware accepts only discrete values. The value closest to the
109 provided input will be chosen as the override value for this param.
113 qcom,hs-rise-fall-time-bp:
115 This adjusts the rise/fall times of the high-speed waveform.
116 The hardware accepts only discrete values. The value closest to the
117 provided input will be chosen as the override value for this param.
118 minimum: -4100
121 qcom,hs-crossover-voltage-microvolt:
125 The hardware accepts only discrete values. The value closest to the
126 provided input will be chosen as the override value for this param.
127 minimum: -31000
130 qcom,hs-output-impedance-micro-ohms:
133 on the D+ and D- paths between the transceiver and cable. This adjusts
135 resistance on the USB. The hardware accepts only discrete values. The
136 value closest to the provided input will be chosen as the override value
138 minimum: -2300000
141 qcom,ls-fs-output-impedance-bp:
143 This adjusts the low- and full-speed single-ended source
146 The hardware accepts only discrete values. The value closest to the
147 provided input will be chosen as the override value for this param.
148 minimum: -1053
