63 minimum: -272
66 qcom,squelch-detector-bp:
69 detect valid high-speed data.
72 minimum: -2090
75 qcom,hs-amplitude-bp:
77 This adjusts the high-speed DC level voltage.
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.
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.
107 qcom,hs-rise-fall-time-bp:
109 This adjusts the rise/fall times of the high-speed waveform.
112 minimum: -4100
115 qcom,hs-crossover-voltage-microvolt:
121 minimum: -31000

137 This adjusts the low- and full-speed single-ended source
138 impedance while driving high. The following adjustment values are based
