larsc: do you think there is an advantage to switching to COMMON_CLK instead of implementing clk_enable etc in the platform code?
<larsc>
mth: yes, already did that
<larsc>
save quite a few lines
<mth>
oh, then I'm looking at the wrong branch
<larsc>
localy
<mth>
ah
<larsc>
I haven't been able to integrate your pll changes into it
Caly__ has quit [Ping timeout: 276 seconds]
<larsc>
yet
<mth>
could I have a look at what you have so far? I want to do the same switch to the JZ4770 code
<larsc>
yes, I'll push it later
<mth>
ok, thanks

larsc: in the mmc driver, if no card detect irq is specified in the platform data, host->card_detect_irq is not initialized
<mth>
which means it would be zero because of kzmalloc, I think
<mth>
however, 0 is a valid irq number, so it will freed at module removal
Calyp_ has quit [Ping timeout: 240 seconds]
<larsc>
no zero is not a valid irq number, although the check in remove() might be wrong
<larsc>
but I reworked that codepath as well
<larsc>
and it's gone now

larsc: are you sure that 0 is not valid ? i think that's just what i got in the old atusb code (that politely asked for the first unassigned interrupt)

yes

mth: I just pushed a jz-3.9-clk branch
<apelete>
oh boy, I just spent a couple of hours tonight trying to solder a serial output to my NN, and only succeeded soldering 1 wire out of 3
<apelete>
what a waste :-(
Caly__ has quit [Ping timeout: 256 seconds]
<apelete>
the surface under the battery looks messy now, I hope I didn't melted the pads off...
<mth>
larsc: thanks
<mth>
that's a lot of changes, fortunately most are deletes :)
<larsc>
yes the diffstat looks pretty good
<larsc>
I'll probably send this upstream for 3.12
Calyp_ has quit [Ping timeout: 240 seconds]
<pcercuei>
jz4740 support finally upstream?
<mth>
larsc: you could use devm_request_irq in the last DMA patch, now that DMA is a device
<mth>
pcercuei: jz4740 support has been upstream for ages
paul_boddie has joined #qi-hardware
<larsc>
two years or so
<mth>
we were talking about using the common clock framework instead of the custom clock implementation
<larsc>
apelete: were you using candles to melt the tin?
<paul_boddie>
apelete: Oh well! I managed to spend a good hour soldering four connections to a board recently, and I'm sure people would be unhappy with the joints, but they did work.
<pcercuei>
is jz4770 upstream as well?
<mth>
no, only 4740
<pcercuei>
ok
<mth>
frantony and d_smagin are looking at making a clean 4755 kernel though
<mth>
so maybe at some point we can combine all 47xx kernels
<mth>
I'm currently cleaning up the GPIO usage in our 4770 kernel
<apelete>
larsc: what do you mean by candles ? I used a sharp soldering iron tip to melt the tin (not the smallest but relatively small)
<apelete>
apparently the pads are stll in place (cleaned with a desoldering pump), will try again tomorrow
Calyp_ has joined #qi-hardware
<larsc>
apelete: I'm just kidding, because it took so long
<apelete>
larsc: not funny at all :D
<apelete>
anyway, I'll try again tomorrow, making sure I tin the pads before try to solder the wires
<paul_boddie>
apelete, larsc: My problem seems to be getting the iron to be hot enough at the right point: the tip! That and flux-cored solder not apparently being enough to get the solder to behave.

<apelete>
paul_boddie: working with cheap tools & materials here: 35W soldering iron and not-flux-cored solder. but I won"t be too fast to blame it on the tools or materials, my problem seems to be between the chair and the soldering station :-)
<paul_boddie>
apelete: I'm no soldering expert. I managed to solder connections to the UBB precisely once successfully, but it has been downhill from there ever since then. :-/
<paul_boddie>
I do actually blame the tools. ;-)
<mth>
I always prefer to solder by daylight, it's much easier to see what I'm doing then
<apelete>
paul_boddie: ha ha :D
<paul_boddie>
But I'm happy anyway because I got my experiment to work. I'll try and add a wiki page about it soon.
<paul_boddie>
mth: Daylight isn't a problem where I am for most of the day, so bad light is not an excuse I can use at the moment. :-)
