[PATCH v2 2/5] drm/panel-simple: Don't wait longer for HPD than hpd_absent_delay

[Stephen Boyd]

Quoting Douglas Anderson (2021-01-15 14:44:17)
> If a panel has an hpd_absent_delay specified then we know exactly how
> long the maximum time is before HPD must be asserted.  That means we
> can use it as a timeout for polling the HPD pin instead of using an
> arbitrary timeout.  This is especially useful for dealing with panels
> that periodically fail to power on and need to be retried.  We can
> detect the problem sooner.
