The RTC wakealarm of the sun6i driver was easy to fix. I just needed to add a call to device_init_wakeup. Here's the patch: https://pastebin.com/Y5Z5cgsW
<Alexis3D>
I get an interrupt from it, which is pretty good
<libv>
Alexis3D: create a patch with git am, and send it to the ml
<Alexis3D>
libv: the bad news is that it doesn't allow my Pine H64 to wakeup from suspend, though. The alarm gets set correctly, but the PM suspend routine prints out a -22 error
<Alexis3D>
But I guess that it is unrelated to the RTC itself
<Alexis3D>
Is that good enough for submitting?

yes, hoping to have generated an uneven amount of escapes so parsers go mad trying to find an escaped character
<hellsenberg>
houdini!
<mru>
I heard about some old C compiler that went mad on seeing a long string of question marks inside a comment
<mru>
it was desperately trying to parse it as some kind of super-trigraph
<libv>
a few years ago i had to flash a usb microcontroller remotely, with it attached to a windows machine, we ended up using a cygwin version of openssh.
<libv>
as the win10 built in ssh did not do keys
<libv>
to get one space across, we had to provide _8_ escapes
<libv>
it took a while before i became that desperate to just try more escapes

for that one, would use csi0/1
<libv>
for that, one would use csi0/1
<MoeIcenowy>
but is there anyone that wants to work on TVD?
<wens>
you also need a source for that. maybe another board doing composite output?
<MoeIcenowy>
maybe
<KotCzarny>
wens, cvbs cams are a plenty
<KotCzarny>
basically last 2-3 decades
<KotCzarny>
libv: would csi allow cable runs of 1.5-2meters long?
<MoeIcenowy>
KotCzarny: I think no
<KotCzarny>
yup.
<MoeIcenowy>
according to Pine64, it cannot even run from the mainboard of PineBook to the top of the LCD
<KotCzarny>
thats why cvbs still has a place
<KotCzarny>
unless you grab+encode+stream
<MoeIcenowy>
btw, saying car
<KotCzarny>
but that means you have to have multiple boards
<MoeIcenowy>
I remembered a strange driver called "sunxi_car_reverse" in Allwinner 3.10 BSP
<KotCzarny>
ya, for secondary cam probably?
<libv>
yes, reversing cams often are cvbs
<MoeIcenowy>
it seems to source from TVD
<MoeIcenowy>
says "Fast car reverse image preview module"
<libv>
but dashcams have short distances between camera and soc
<MoeIcenowy>
for V3s car recorder standard design
<MoeIcenowy>
the back camera is a USB one
<libv>
there are regulations as to how long it is allowed to take to have reverse (gear) engaged, and it being shown on the infotainment system, and yes, that needs to be pretty fast
<libv>
not impossible though, but code quality in automotive usually is pretty bad
<MoeIcenowy>

IIRC the Allwinner chips have a MUSB controller and a normal EHCI controller for a USB port. Does anyone know what sub-system controls which gets wired to the port or is just whatever controller is enabled?
<KotCzarny>
musb has its own port
<karlp>
isn't it a mux in front of the same port? one used for device, the other for host?
<KotCzarny>
musb can do both? or no?
kaspter has quit [Ping timeout: 264 seconds]
<dgp>
karlp: I thought there was a mux. I remember seeing patches for using the MUSB controller for host because the EHCI part wasn't working well at one point
<karlp>
KotCzarny: it _can_ but it was considered buggy, so it uses one for each.
<karlp>
that's how I understand it....
<dgp>
karlp: That sounds like the mux is set somewhere and then forgotten about?
<karlp>
no... there's some glue that handles it "properly", if you have the right things turned on.
<dgp>
Looks like the mux control is in the phy code. Thanks :)

reinforce has quit [Quit: Leaving.]
<dgp>
MoeIcenowy: yes. I'm looking at something that has almost the same setup. An EHCI controller, MUSB controller and then a mux before the USB phy. The MUSB block seems to be configured without host support so the vendor code has a hack to switch the mux when the id pin changes
<MoeIcenowy>
no
<MoeIcenowy>
it has host support
<MoeIcenowy>
but the host support of MUSB is always very weak
<MoeIcenowy>
low-performance and bad compatiblity
<dgp>
That's possibly why this vendor code switches the blocks then. I was sure sunxi did it but couldn't find where.
<MoeIcenowy>
in fact the dual-controller design is only since H3

on A10~A33 you can experience the MUSB's weakness on OTG host mode

I made my own board using the V3s. Im using opensuse Tumbleweed and reading the linux-sunxi.org I need to cross-compile u-boot and kernel to run linux on board
