<DC-IRC>
[Discord] <amazingfate> You can backport it.
<DC-IRC>
[Discord] <narga_64> What's wrong with that?
<DC-IRC>
[Discord] <narga_64> Nah, they're using gpio1-d3 🤓
<DC-IRC>
[Discord] <mariob> Yeah
<DC-IRC>
[Discord] <mariob> They're using 2 mosfets
<DC-IRC>
[Discord] <rpardini> Nice, thanks.
<DC-IRC>
[Discord] <rpardini> Nothing wrong with it, the thing has 15 PWMs so I guess using one for 2-pin fan people is a valid and really value-adding.
<DC-IRC>
[Discord] <rpardini> That said I'm a 4-pin person so I'll have to ignore all that nice circuitry...
<DC-IRC>
[Discord] <rpardini> Nice, thanks.

<DC-IRC>
[Discord] <rpardini> the tacho confuses me though -- seems like `pwm-fan` wants a simple interrupt (eg `IRQ_TYPE_EDGE_FALLING`), not a full `&pwm`
<DC-IRC>
[Discord] <t1msu_87222> There is no tacho signal supported in this circuit
<DC-IRC>
[Discord] <t1msu_87222> there will be a dts in next mainline for this board:
<DC-IRC>
[Discord] <rpardini> so yeah I use `&pwm5` to drive it
<DC-IRC>
[Discord] <lanefu> Yeah I uhhh fucked mine up trying to debug and drive a 5v directly
<DC-IRC>
[Discord] <lanefu> Yeah I uhhh fucked mine up trying to debug and drive a 2pin 5v directly
<DC-IRC>
[Discord] <rpardini> and `&pwm9` (actually through `GPIO3_B0`) to read tacho
<DC-IRC>
[Discord] <rpardini> nothing too melty/permanent I hope?
<DC-IRC>
[Discord] <lanefu> That's sweet dude. I uhh will probably order a fan in 5 min
<DC-IRC>
[Discord] <lanefu> I think I killed one of the fets when I had my multimeter out because it can barely spin a fan at any setting now. I had it semi usable prior to incident
<DC-IRC>
[Discord] <rpardini> yeah _frak_ those 'fets
<DC-IRC>
[Discord] <rpardini> still gotta find screws that fit -- Noctua's own are too phat
<DC-IRC>
[Discord] <lanefu> I've got a box of screws that fit
<DC-IRC>
[Discord] <lanefu> Okay ordered one lol
<DC-IRC>
[Discord] <lanefu> Will be here Sunday
<DC-IRC>
[Discord] <rpardini> cool. should have an overlay by then
<DC-IRC>
[Discord] <lanefu> Baller
<DC-IRC>
[Discord] <rpardini> I'm unsure about `fan-supply = <&vcc_5v0_sys>;` and specially if I need to disable `pwm9` (`GPIO3_B0`), or even if I should use any random pin instead
<DC-IRC>
[Discord] <lanefu> Hows 6.9.x doing on rk3588?
<DC-IRC>
[Discord] <rpardini> No idea, I'm on 6.10-rc5 and headless
<DC-IRC>
[Discord] <lanefu> Oh sweet
<DC-IRC>
[Discord] <lanefu> Is that what edge is on?
<DC-IRC>
[Discord] <lanefu> I haven't built rk3588 edge since May
<DC-IRC>
[Discord] <lanefu> I've been hibernating
<DC-IRC>
[Discord] <rpardini> yeah Narga's work
<DC-IRC>
[Discord] <rpardini> I mean everybody's work but Narga did a large reorg of patches for 6.10
<DC-IRC>
[Discord] <rpardini> I've no idea about HDMI though, which seems is all ppl care about
<DC-IRC>
[Discord] <lanefu> Doesnt 6.10 have some of the first DVFS fixes for rk3588?!
<DC-IRC>
[Discord] <rpardini> I lost track of what's where...
<DC-IRC>
[Discord] <lanefu> Anyway I think it does so I'm excited to see that SoC run cooler
<DC-IRC>
[Discord] <lanefu> Anyway I think it does so I'll be excited to see that SoC run cooler
<DC-IRC>
[Discord] <rpardini> there's _some_ recent cpufreq work but I can't remember if it's .10 or .11
<DC-IRC>
[Discord] <lanefu> Collabora's matrix says 6.11 it seems
