brown paper bag bug: the dptx-phy node in t8112.dtsi and t602x-dieX.dtsi use power-domain in stead of power-domains. Why was it working at all? On initial probe we were probably saved by simple-framebuffer using the dptx-phy power-domain but after that. I think/hope this explains most or all of the weird issue we see with HDMI on M2* desktop systems.

Fixed in https://github.com/jannau/linux/commits/asahi-wip/

500ms msleep() in the threaded HPD irq handler which might ack as debounce or is just a significant delay seems to improve stability with a troublesome display display here. See 5ef7d920caa52
