if I were to do my "own" dts in that way, I'd have to patch arch/arm/dts/Makefile in order to include mine in the list
<jonkerj>
nice way by the way
<longsleep>
jonkerj: yeah well you can maintain any kind of patches with such an approach
<jonkerj>
I'm going to try if a dts overlay is going to do what I want
<jonkerj>
in that way I can keep it completely out of tree

frankly most of the software support stuff is SoC related, so other boards shouldn't be much different

ok, I've got a dt overlay src, a patched dtc to compile it, but it is a mystery to me how to add/load/create it into the kernel
<jonkerj>
on BBB people use a "CapeMgr" to do so
<jonkerj>
saw some old posts about configfs, but that seems bygone days
<jonkerj>
anyone an idea on how to load the dtbo into the kernel?
<jonkerj>
ssvb: the IRC logs suggest that you may know how to tackle this (load DT overlay from userspace)
<ssvb>
jonkerj: this experiment failed at the hardware level, because if I can't mount the LCD shield on the supposedly Arduino compatible expansion headers, then it's a full stop :-)
TheLinuxBug has joined #linux-sunxi
<jonkerj>
heh, yes :-)
<ssvb>
what kind of hardware are you trying to use with a DT overlay?
<jonkerj>
at first, I'd like to expose UART2 on the expansion header of my orange pi
<jonkerj>
of course, I could do this by creating a dts which includes the in-tree dts for the board
<jonkerj>
I was hoping/thinking DT-overlay was the way to go
<jonkerj>
if that works, I'm going to attach pressure/temp/humidity sensors to i2c/spi busses
<jonkerj>
maybe TFT
<jonkerj>
but first a simple case, the uart
popolon has joined #linux-sunxi
<buZz>
hmhm, maybe i should just order a Pine64+ then
<ssvb>
maybe it's best to look at how the BBB people are solving this problem? because inventing a new NIH solution is not going to make anything easier for anyone
<buZz>
or one of em
<jonkerj>
ssvb: well, as far as I understand, the dt-overlay is already in place
<jonkerj>
difference is that BBB has some hotplug-way to detect capes, and that mechanism triggers the in-kernel API for loading overlays
<jonkerj>
there used to be a way through configfs, but that seems gone
<ssvb>
yes, this is a very reasonable approach
<jonkerj>
I am really hoping that I miss something or that there is an obscure tool to fix it
<jonkerj>
s/fix/load/
<ssvb>
I mean, without the autodetection feature, the whole thing requires a competent user and a bit of hackery
<jonkerj>
it is the same level of competence/hacking as writing a 'include overlay' dts and booting it
<jonkerj>
imho
<jonkerj>
but much cleaner
<jonkerj>
(imho too)
<ssvb>
the users still needs to know what kind of shield exactly they are using, then find and load the right overlay
fire219 has joined #linux-sunxi
<jonkerj>
that's true, ssvb
<jonkerj>
but the current situation with sunxi is that there is no user friendly way to do so
<MoeIcenowy>
as I know
<MoeIcenowy>
mripard sent out a patch for U-Boot dt overlay support
<MoeIcenowy>
however it takes time for it to be merged into U-Boot release
<ssvb>
jonkerj: this might be a tough challenge for many of them, and some may just resort to a trial and error method, potentially damaging their hardware
<jonkerj>
my understanding of the inner workings is limited, but how does u-boot fit in this story?
<ssvb>
jonkerj: while a properly educated user can easily patch and rebuild the dts file
<ssvb>
if BBB people have introduced shields identification and autodetection feature, then this is IMHO a proper way to handle this
<jonkerj>
for shields it is
<jonkerj>
in the meanwhile, I'll play with my non-shield expansions through a 'include overlay' dts :-)
<apritzel>
jonkerj: do you just want to hack something?
<apritzel>
jonkerj: then using U-Boot's "fdt" command is quite handy
<apritzel>
you can create, change, remove DT nodes at will
<apritzel>
you can then put a sequence of those commands into some .scr file and load/run it in a more automated fashion
<jonkerj>
hmm, that sounds really useful in my situation
<jonkerj>
a runtime overlay from u-boot

dtbo seems to be a bit a thing of the future atm ;-)
<ssvb>
but considering that there are very few users for this feature, it does not look like it makes a lot of sense to waste time implementing something more generic and universal
<jonkerj>
sounds fair
