Dcs35l36.txt102 - cirrus,vpbr-en : VBST brownout prevention enable. Configures whether the
103 VBST brownout prevention algorithm is enabled or disabled.
105 0 = VBST brownout prevention disabled (default)
106 1 = VBST brownout prevention enabled
110 - cirrus,vpbr-thld : Initial VPBR threshold. Configures the VP brownout
114 amount delay between consecutive volume attenuation steps when a brownout
115 condition is present and the VP brownout condition is in an attacking state.
117 - cirrus,vpbr-atk-vol : VP brownout prevention step size. Configures the VP
118 brownout prevention attacking attenuation step size when operating in either
