<Tonymac32> Cool. I've pretty much dialed in a "real" mainline device tree for 6.6, can circle around and look at that since we have a Collabora build option.
<DC-IRC>
<Tonymac32> Tenkawa there is no video stack at all on this SoC in mainline
<DC-IRC>
<Tonymac32> And since the type C PD is almost useless I'd expect this isn't a value add for the 5B
<DC-IRC>
<tenkawa42> I don't use video
<DC-IRC>
<tenkawa42> Nor PD
<DC-IRC>
<tenkawa42> My Rock5's are headless and on set voltage ports. I learned in pre-release testing not to trust PD as far as you could throw it on them.
<DC-IRC>
<Tonymac32> 😆
<DC-IRC>
<Tonymac32> My type C hubs that can power the board and breakout the functions *also* negotiate the PD, even with dumb power to them. So at least on my side I have nothing reliable to use that "might as well be a barrel jack" Type C
<DC-IRC>
<tenkawa42> ouch... Yeah mine are fixed voltage
<DC-IRC>
<Tonymac32> On the T6 though it's a separate port from power
<DC-IRC>
<Tonymac32> So this patch is actually useful there
<DC-IRC>
<tenkawa42> I have adapters from 9v to I think 24v also if I need them
<DC-IRC>
<tenkawa42> (after I discovered they weren't bad and were just weird how they worked)
<DC-IRC>
<Tonymac32> Yeah I fed 12V through my barrel to type C adapter to my hub, and then the hub negotiated the supply and boot looped 😆
<DC-IRC>
<tenkawa42> They have to be plugged in twice
<DC-IRC>
<Tonymac32> Yeah I read that, weird
<DC-IRC>
<tenkawa42> The consistency was startling
<DC-IRC>
<Tonymac32> FriendlyElec got burnt with Type C PD on the NanoPi M4 family and a couple others, they learned
<DC-IRC>
<tenkawa42> ouch
<DC-IRC>
<tenkawa42> I've really put my power supplies to good use now...
<DC-IRC>
<Tonymac32> So on the R5S it's a microcontroller doing the PD like Radxa used to do
<DC-IRC>
<Tonymac32> And the T6 just has big old barrel jack
<DC-IRC>
<lanefu> barrel jacks are about friendship
