Why don't you use the standard debian installation? It have mainline kernel 
3.16, with the possibility to install more recent kernel from backports.

Take a look at this link: https://wiki.debian.org/InstallingDebianOn/Allwinner

Kernel 3.4, nowadays is deprecated and not supported anymore.

In fact, there should be no audio card driver as proposed here:
with such a simple layout
CPU DAI (sun4i-a10-i2s) -> CODEC DAI (sun8i-a33-codec)
the 'simple-card' does the job.

BTW, I have a I2S/PCM/TDM driver for the H3 and A83T.
But, as it works with HDMI and contains echanges with the DRM driver,
it cannot go yet to the mainline...

No, not really. You could have LVDS to something bridges as well, but
the bridge setup is already dealt with in the framework, so it
shouldn't have been dealt with in the RGB part in the first place.

[linux-sunxi] Need support for compiling rtl8723bs driver for sinxi linux kernel 3.4.90

2016-10-05 Thread S Saravanan 
Hi,

  I need rtl8723bs wifi driver for interfacing the wifi IC with A10 
olimex board. When i tried to compile the driver from this 
link https://github.com/hadess/rtl8723bs , it shows that it needs kernel 
3.19 or above for compile. I am using official debian image that came from 
the olimex A10 board from his website. Its kernel version is 3.4.90. So 
please give me solution of how to compile rtl8723bs driver source from the 
above github link on the kernel 3.4.90 itself. Hope you guys help me in 
this. 

Thanks in advance.

Now that I've spent some time trying to add my changes for the H3
ontop of your code,  I think this file should be more generic and rely
on the dtsi more. It's pretty A33 specific but with little effort it
can be worked to cover all of the sun8i type drivers. I would change
"allwinner,i2s-controller" to "allwinner,audio-dai" for starters and
then maybe pull in some info for the dai-link from the dtsi.
