The threaded interrupt handler on RK3576 responsible for providing the HDMI HPD capability is currently unreliable, since it's affected by a bug leading to a broken hotplug detection in some cases.
RK3588 is affected by a similar implementation deficiency, however it doesn't seem to cause any functional breakage. The series aims to fix the RK3576 HPD issue and optimize HPD handling on RK3588.
