it looks like is tested on A31.. but is that supposed to work on A20 too? with the proper DTS setup?
<plaes>
sunxi_fan: probably not yet

i see, i do not own an A31 device but i'll give a look to user man / datasheet just to understand how far are the two DE engines.. surely the DRC block is missing on A20, that's what mainly worry me..

i currently have issues with clocks, i suppose that also the CCU DTS cfg for A20 from "linux/sunxi DT-for-4.15" tree/branch could have some issues; i.e.. i'm using the drm-misc-next branch for kernel/modules (actually everything is on fat kernel, of course..) and DTS/DTB from "DT-for-4.15" linux sunxi tree/branch. the kernel is indeed booting on A20 and "just for test" i'm using the plain vanilla A20 Olimex Som Evb dts, but the nfs

later .. [ 0.073683] /cpus/cpu@0 missing clock-frequency property
<sunxi_fan>
i'll post the boot on pastebit. just a minute..
<sunxi_fan>
using the plain vnanilla sun7i-a20-olimex-som-evb.dts of the dt-for-4.15.. maybe it's a too advanced dts for being used on top of a plain vanilla (i mean sunxi_defconfig, of course..) cfg for drm-misc-next that's a 4.13.rc0..

i do not see in the Common Clock Framework kernel config for drm-misc-next branch the SUN4I_A10_CCU... is that a different patch to be applied?
<sunxi_fan>
there are plenty others for Allwinner SOCs (H3 A80 A31 to name a few..) but that one for sun4i/sun7i is missing..

then use linux-next :/

or apply the patches yourself?

KotCzarny, the coreduo sucked. I had one and it was horrible.
<KotCzarny>
works fine here

mine was horrible and then it died.

in fact i'm using one as a h3droid builder

That's a core2duo

was there big difference?

A generation and a ton of performance.

core was basically a tweaked Pentium 3.

the v7 patch about 'CCU for sun4i' can be applied BUT compilation then breaks on missing field ".fixed_post_div" in 'static struct ccu_div pll_periph_sata_clk {} ' .. :-(
<sunxi_fan>
i suppose this patch https://patchwork.kernel.org/patch/9841255/ "[v6,1/6] clk: sunxi-ng: div: Add support for fixed post-divider" went upstream on a different way.. the thread is not clear to me..
<wens>
drm-misc-next conflicts linus' master :/
<wens>
sunxi_fan: it was applied in v6, so the sender drops it from v7
<sunxi_fan>
maybe the linux-next approach + drm-misc-next patch could be a better way to get stuff altogether, so if someone is pursuing that track, i'll gladly stay in "active wait.."
<sunxi_fan>
ok, so i'l try to apply myself too..
<wens>
get linux-next, then merge in drm-misc-next, and sunxi/fixes-for-4.14, sunxi/dt-for-4.15

umh, im getting there... after having fixed the ccu and tweaked someway the dts, here it's the output of drm.debug=3, with the traversal of the components and finally the HDMI is there.. the panel is missing.. is the traversal right, when one have FE0 FE1 <> BE0 BE1 then dedicated BE0 -> TCON0 and BE1 -> TCON1 in A20.dtsi, then the panel is added.. in EVB.dts.. here the excerpt of the drm.debug=3 https://pastebin.com/5qaBhTHD
