14 to a Embedded DisplayPort AUX bus (see display/dp-aux-bus.yaml) without
17 board, either for second-sourcing purposes or to support multiple SKUs
21 represented under the DP AUX bus. This means that we can use any
22 information provided by the DP AUX bus (including the EDID) to identify
27 provided anywhere on the DP AUX bus is the power sequencing timings.

91 hpd-reliable-delay-ms:
94 panel's power-supply before the HPD signal is a reliable way to know
95 when the AUX channel is ready. This is useful for panels that glitch
96 the HPD at the start of power-on. This value is not needed if HPD is
99 hpd-absent-delay-ms:
105 include the hpd-reliable-delay, so if hpd-reliable-delay was 80 ms
106 and hpd-absent-delay was 200 ms then we'd do a fixed 80 ms delay and
