Hi all,
I'm new in these communication things and hope it is ok what I do. Thanks a lot
for the audio patch from Vasily. It is working fine for me.
I have an Allwinner A64 device with an LVDS display and want to bring it to
live.
* The display is running with the original old Android system
* I use 4.20-RC2 as code base with the audio patches from Vasily
* My backlight dts node is working and I can change the brightness from command
line.
* LVDS pins are connected to D12 to D21.
* Reset pin is at PD24
* VCC is connected to "reg_dc1sw"
>From the sunxi mainline effort page I know that it should run, but untested
>for the A64.
I used the LVDS dts code from the A83T device (TBS A711 Tablet), because this
was the only one where I could find lvds dts code.
I added the Pin description to main A64 dtsi (could be reused if someone wants
to add it to the kernel. For me the process is currently a little bit unclear
how I can set it up correctly):

I'm compiling with Buildroot and added to the default ARM64 mainline kernel
config file CONFIG_DRM_PANEL_LVDS=m CONFIG_SUN8I_DE2_CCU=y
The system is booting. The backlight goes on with white display. If the drm
module is loaded the color is changing to black, but backlight is on.
The reset pin is at 3,3V which is ok, checked with manual. I used fb-test but
nothings.
I searched a lot about the TCONs but not really understand the endpoints. Is
endpoint 0 for TCON0 on A64 ok for LVDS and is the driver doing the rest for it?
If someone has any hints this would be great. I searched a lot but found not
really helpful information for me about these TCON. I looked also into the
binding documentation for sunxi.
Regards
John-Eric
