<maz> eballetbo: I've tried to upgrade one of my kevin to 4.19-rc5, and at least USB seems dead (Failed to get clk 'ref': -2...).
<maz> eballetbo: does this ring any bell?
<eballetbo> maz: I see the same errors but usb ends working for me

<maz> eballetbo: odd. I guess I need to spend some quality time bisecting.
aalm has joined #linux-rockchip
<maz> eballetbo: don't you get a "failed to initialize core' message after the failure to get the clock?
<aalm> teletype, i think you'd want the u-boot to have this:
<eballetbo> maz: let me check ...
<maz> eballetbo: 4.18 has the same 'clk' messages indeed, but boots just fine.
<eballetbo> maz: just booted a 4.19-rc5, I have these errors
<eballetbo> [ 1.922215] dwc3 fe800000.dwc3: Failed to get clk 'ref': -2
<eballetbo> [ 1.942450] dwc3 fe900000.dwc3: failed to initialize core
<eballetbo> [ 1.936025] dwc3 fe900000.dwc3: Failed to get clk 'ref': -2
<eballetbo> [ 1.928920] dwc3 fe800000.dwc3: failed to initialize core
<eballetbo> [ 2.478668] dwc3 fe800000.dwc3: Failed to get clk 'ref': -2
<eballetbo> [ 2.503479] dwc3 fe900000.dwc3: Failed to get clk 'ref': -2
<eballetbo> but my usb-c dock is detected and ethernet working
<eballetbo> I suppose it defers and succeeds later
<maz> eballetbo: OK. this would tend to indicate that there is a dependency that doesn't get resolved.
<eballetbo> maz: I can share my defconfig if that helps
<maz> eballetbo: could be useful, yes. can you email it?
<eballetbo> maz: you should have mail ...
<eballetbo> maz: let me know if that config doesn't work, I have some patches on my tree applied regarding the usb but shouldn't matter
<maz> eballetbo: thanks for that, I'll give it a go later today.
<chewitt> fwiw .. I see "[ 2.241928] dwc3 c9000000.dwc3: Failed to get clk 'ref': -2" on an Amlogic S912 board (on 4.18) too
<chewitt> although without the "failed to initialize core" messages
<maz> chewitt: it'd be interesting if you could try 4.19-rc5.
<chewitt> i'm working up the enthusiasm for a rebase of a large patch-set to do so :)
<maz> chewitt: ah! ;-)
<mmind00> maz: eballetbo: that clock message is "to be expected" ... both dwc3-simple and the dwc3 core do clock handling nowadays for whatever reason and the expected clock names are actually differewnt

<mrjay> rk3066 power domain patches ... cool
<mmind00> mrjay: hehe ... only took me a year to post v2
afaerber has joined #linux-rockchip
<mrjay> mmind00: not that long i think
<mmind00> mrjay: september 2017 was v1 ;-)
<mrjay> mmind00: my u-boot patches also wait similiar timeframe
<mmind00> hehe
<mrjay> :)
<mrjay> mmind00: i see (on patchwork) you are into display subsystem now
<mrjay> mmind00: cool
<mmind00> mrjay: yep ... and while I only work on rk3188 right now, rk3066 should be similar and for that Rockchip even has an hdmi driver in their vendor tree
ldevulder has joined #linux-rockchip
<mrjay> mmind00: i see
<mrjay> mmind00: so if i understand this correctly, rk3066 needs lcdc driver + hdmi driver?
<mmind00> mrjay: correct
<mrjay> mmind00: awesome that rockchip didn't forget rk3066.
<mrjay> mmind00: i need to find time and finish that u-boot patches and mainline them
