<a1d3s> ssvb i changed usb cable , power supply and the usb port for power , first i was using the otg port
<a1d3s> ssvb keyboard works on console but not in lxde
<plaes> do you have correct xorg driver?

<ssvb> a1d3s: about non-working keyboard/mouse, can you pastebin your /var/log/Xorg.0.log ?
<ssvb> a1d3s: regarding the power supply being the culprit, thanks for sharing this information
<a1d3s> i think it was the otg port or the cable
<ssvb> I have had plenty of troubleshooting discussions with people, who are in denial and refuse to consider their power supply as a potential source of troubles :-)
<a1d3s> booth power supply have 2A
<a1d3s> but i know sometimes the power supply is a known problem ;)
<ssvb> regarding your Xorg.0.log, I don't see it even trying to load the xorg input drivers
<a1d3s> yes this is installed
<a1d3s> and xkdb and synaptics too
<ssvb> the log also says "If no devices become available, reconfigure udev or disable AutoAddDevices"

<alex___> I've run a new kernel (4.1.0-rc1) from mripard and get this message while booting my cubietruck. reg-fixed-voltage ahci-5v: could not find pctldev for node /soc@01c00000/pinctrl@01c20800/ahci_pwr_pin@1, deferring probe what does this mean? the full output is on http://pastebin.com/VFeGcE3X. How can I fix it ?
<mripard> alex___: it's normal
<alex___> and this happens with the spi driver http://pastebin.com/CQV8XwmX
<wens> alex___: "deferring probe" <= postponing loading the driver until the required pinctrl device is loaded
<wens> alex___: it's just the kernel's way of handling dependencies between devices/drivers
<mripard> alex___: because you made some modifications to it.
<mripard> and probably you added a spidev device
<alex___> yes
<mripard> then that's why.
imcsk8|zZz is now known as imcsk8
<alex___> like your write yesterday
<mripard> I most certainly didn't write that yesterday
<alex___> I enabled it in the dts file. is that false?
<mripard> there's a whole thread on the mailing list about that, please read this

<wens> mripard: was there a specific reason for having the PRCM as an mfd, instead of just broken into clocks/resets and whatever else is in there?
<wens> afaik the smp code wants to map the whole address space, but that could be dealt with using clock gates, reset controls, and regulators
<wens> not that it's any prettier
<mripard> wens: not really
<mripard> it needs to poke random bits that cannot really be tied to one device
<mripard> ah, yes, but it's true for the PRCM alon
<mripard> yep
<mripard> you could do it through the power domains and the regulator
<mripard> I don't know whether they are initialized soon enough though
<wens> it feels like the PRCM is some place to stick stuff that doesn't belong to any one device :(
<wens> on the A23 a whole bunch of codec related stuff is in there...
<mripard> which it is :P
<wens> i don't know, my gut feeling is that in the future the mfd description would be limiting
<mripard> why ?
bsdfox has quit [Ping timeout: 240 seconds]
<wens> for example the mfd framework only binds to the first node of multiple nodes with the same compatible
<wens> like for mod0 clocks
dack has joined #linux-sunxi
<mripard> yeah, and it should be fixed
<wens> which could probably be dealt with, but the ordering is not easy to get right
<wens> the child node order has to match the driver, meaning it is part of the binding i guess
<wens> there's also a problem of not being able to share the address space, like if i wanted to add a configurable 24M clock on the A80
<mripard> if you're having a dt node, then it's easy, just pass the right child dt node
<wens> the register is in PRCM space, but since it is _the_ main clock of the system, it should be initialized early, not part of the mfd
<mripard> if you're having resources, then you don't really care about the order, do you?
<wens> but that is a kernel limitation
<mripard> yeah, that part is problematic
<wens> mripard: but how do you match dt nodes with resources?
<wens> otherwise you could get the wrong phandle for clocks?
<mripard> by their order?
traeak1 has joined #linux-sunxi
traeak1 has left #linux-sunxi [#linux-sunxi]
<wens> so the order is part of the DT binding, but not that obvious
<mripard> if you consider that all nodes are supposed to be ordered by their base address
<mripard> then there's not much space for differences
<wens> i guess so, unless someone were to add the second clock later, and then someone else has mismatched kernel/DT versions lol
<wens> (which i totally see us doing)
<mripard> just a second
<mripard> you're arguing about "let's break the whole binding"
<mripard> and now you're using the DT ABI as an argument ? really ? :)
<wens> no, i'm arguing about forgetting the old PRCM binding when doing the A80, starting from scratch :)
<wens> for A31/A23, what's done is done
<wens> if some day we add 1 wire support to A31, something silly might happen, but that's for another time
<wens> to summarize, i'm asking if we should just split up the PRCM on the A80, i.e. remove the PRCM node
<wens> maybe i'm overthinking this
vishnup has joined #linux-sunxi
<mripard> I don't know
<mripard> now that it's merged, maybe using simple-mfd would ease the poin
<mripard> *pain
leviathancn has joined #linux-sunxi
<mripard> for the clocks though, I think it doesn't care about the tree itself
<mripard> it just iterates over all the compatible and call the matching function
<wens> true, the limiting factor is address space sharing
<wens> iirc of_io_request_and_map() doesn't allow sharing
<mripard> ah, right
<mripard> and we don't have a reg property in the subnodes
Andy-D__ has joined #linux-sunxi
<mripard> I don't really care about having a reg property or not in the subnodes to be honest
<mripard> everyone else is doing it, why not us?
<wens> oh really?
<wens> also, i've seen the simple-mfd binding on the ML, but couldn't find it in the tree
<Skylark> hmmm
<Skylark> i wonder if the A20 sleep issues are somehow related to most A20 boards having the AXP209 hooked up to NMI
<Skylark> since by default we store the DRAM calibration data in the AXP209 GPs
<mripard> wens: simple-mfd is just a joke
<Skylark> i added some careful tracing code there and that's what it seems to be, maybe
<mripard> it's just a new compatible for simple-bus
<Skylark> or maybe Rtc
<wens> mripard: yeah, but i remember someone asking people not to use simple-bus for non-bus stuff :p
<mripard> yeah
<mripard> so they just introduced a new compatible for the exact same thing
