Though if someone wants to take over I can forward any design plans I have.

Well, my plan was to get at least minimum bits mainlined and then build additional features on top. Wens, it would be cool though, if you could share your plans. Unfortunately I have only single A10 device (with LVDS and mini-HDMI) but I don't actually have other LVDS-displays I could easily use with A20 devices (I have CubieTruck and A20-Olinuxino Micro). Päikest, Priit :)

I understand that, but now that we have the DT stability to maintain, I want to make sure that everything is correctly represented from day one, with code that works. Otherwise, we might or might not be able to fix things properly later down the road (or at the expense of ugly hacks). Maxime
Hi If you want I work with a Allwinner A20 (my board are derived from OlinuXino-Micro-A20), and I will interest with LVDS function. I use your patch but I have nothing to display on my screen. You can see my work on https://github.com/Philippe12/linux-sunxi/tree/sun7i-A20-lvds My hardware is good, it word with u-boot and a older kernel 3.4.104 I use a dlc screen (dlc0700DDG-T-11) my fault is probably on simple-panel information but I didn't seen were If you can tell me some things to check. Thank for your help Best regards Philippe FOUQUET Le lundi 13 février 2017 17:46:48 UTC+1, Priit Laes a écrit : > > On Mon, 2017-02-13 at 17:20 +0800, Chen-Yu Tsai wrote: > > On Mon, Feb 13, 2017 at 5:16 PM, Maxime Ripard > > <maxime...@free-electrons.com <javascript:>> wrote: > > > Hi, > > > > > > On Sat, Feb 11, 2017 at 07:43:59PM +0200, Priit Laes wrote: > > > > Added basic display pipeline consisting of tcon, display backend > > > > and > > > > frontend blocks. > > > > > > > > Signed-off-by: Priit Laes <pl...@plaes.org <javascript:>> > > > > --- > > > > arch/arm/boot/dts/sun4i-a10.dtsi | 104 > > > > +++++++++++++++++++++++++++++++++++++++ > > > > 1 file changed, 104 insertions(+) > > > > > > > > diff --git a/arch/arm/boot/dts/sun4i-a10.dtsi > > > > b/arch/arm/boot/dts/sun4i-a10.dtsi > > > > index ba20b48..70991c9 100644 > > > > --- a/arch/arm/boot/dts/sun4i-a10.dtsi > > > > +++ b/arch/arm/boot/dts/sun4i-a10.dtsi > > > > @@ -779,6 +779,45 @@ > > > > #size-cells = <0>; > > > > }; > > > > > > > > + tcon0: lcd-controller@1c0c000 { > > > > + compatible = "allwinner,sun5i-a13-tcon"; > > > > > > There's a few bits here and there that need to be setup differently > > > in > > > A10, so you cannot reuse that compatible (same thing for the > > > other). > > > > > > Also, I'd really like to have all the blocks listed here, and not > > > only > > > the first pipeline.
