(always-on and boot-on) Without them it breaks on this board (v7.3): - with panfrost not loaded, the regulator core turns vdd_gpu off 30 s after boot and the next warm reboot hangs in the DDR init (TPL, DDR blob v1.25, at "change freq to 856MHz"), 2 of 2; only removing power recovers it. All 119 boots in my console log passed there with the rail on. - panfrost loaded after that: "failed to get ack on domain 'gpu'", the GPU stays deferred, since pd_gpu powers up before mali-supply is on. So I would keep always-on and boot-on, as the other RK3399 boards do.
