Thanks for answer.
I’m still learning this area 
I’m using your 4.14.71 kenel and so far working perfectly
i see new drm-patches…are these now compatible with fbdev?
https://patchwork.kernel.org/project/linux-mediatek/list/?series=25989
And
https://patchwork.kernel.org/project/linux-mediatek/list/?series=26061
tried these (first patches, second are only documentation) here (+clock-options, +dtsi, without fbdev):
but get only this:
[ 0.775991] mediatek-drm 14000000.dispsys: Adding component match for /ovl@14007000

[ 0.834768] mediatek-drm-hdmi: probe of 14015000.hdmi failed with error -22
seems anything in clocks is wrong, i fixed the clk-error, but the probe-erros is still present and no xserver starts
These are incomplete patches. We will add remains gradually.
But you could take:
second are device nodes which i have added already (is there any change in resend except sorting??).
first one applied, but still the same error (reverted my clock-patch)
[ 1.057324] clk: failed to reparent hdmi_sel to hdmitx_dig_cts: -22
[ 1.063754] mediatek-drm-hdmi: probe of 14015000.hdmi failed with error -22
replaced dts(i)-nodes with these from resend-patch and got this compile-warnings:

Try to plug out the cable and then connect it again.
unsupported mode again, as expected because i see the purple screen from preloader
but i get an error after x-server was started a while…

dts-nodes from series above (your resend) are compatible with the new drm-patches? then i try to include the other 4 again
drm.txt (17.2 KB)
Everything looks okay with the latest patches. But there’s a known issue - we need to plug out the cable and then connect it. We will fix it soon.
then i remove the branch and wait for fix including necessary patches (dts,…)
You can still see the hdmi output (at least) on your R2.
currently i have no output but maybe the dts-node are changed…only updated nodes from your resend patch after adding nodes from my other branch
i try to make a clean branch with these patches based on
- https://patchwork.kernel.org/project/linux-mediatek/list/?series=15283
- https://patchwork.kernel.org/patch/10588951/
- https://patchwork.kernel.org/project/linux-mediatek/list/?series=25989
and your additional patch
https://github.com/frank-w/BPI-R2-4.14/tree/4.19-rc7-hdmiv5
still “unsupported mode”, no mediatek-hdmi-ddc, no other fail-message
if i kill xinit i get endless repeating

but you’ve said, that these patches are incomplete…so i just wait
but you’ve said, that these patches are incomplete…so i just wait
Though we have some patches in the queue, we still could use drm/hdmi normally.
i try to make a clean branch with these patches based on

I tested kernel 4.19 with these patches (and it works), so I assumed you should get a successful result.
i’ve added these patches to above repo (https://github.com/frank-w/BPI-R2-4.14/tree/4.19-rc7-hdmiv5) but it does not work on my TV, imho v3-patches show xserver, but v5 does not work
same with https://patchwork.kernel.org/patch/10609007/ (v3 12/12) applied
log including x-server: 4.19-rc7-hdmiv5.log (60,4 KB)
from logs it looks well, but unsupported mode on TV instead of working X-Display…i guess it’s a hsync/vsync-issue
Have you found a problem in these patches? Hoping these do not go in mainline because then i need to patch them out to include my old patches
I still could not reproduce your problem in my R2 (I can see debian desktop).
Some of these patches have already been merged, and the only problem is that we need to reconnect the cable if we want to boot up with the 720p (1080p is ok). So… I guess you can try to reconnect it.
I have used 1080p and have reconnected cable…have you compiled my branch for testin (to compare with your code)?
I guess it is a hsync/vsync-problem because of the message,but it does not show settings it gets… btw. I have a 10m cable between r2 and tv
i see no merge in 4.19-rc…maybe it’s merged to matthias bruggers or drm-tree, but not yet in 4.19
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/drivers/gpu/drm/mediatek
drivers/gpu/drm/mediatek/mtk_hdmi_phy.c and drivers/gpu/drm/mediatek/mtk_mt2701_hdmi_phy.c are missing, mst of the other files related to mt7623 are last changed before september 2018
as you see in my logs i try to bootup with 1080p as this setup works with old drivers…all other does not.
Hi @Ryder.Lee!
I’ve compiled and tested Frank’s https://github.com/frank-w/BPI-R2-4.14/tree/4.19-rc7-hdmiv5 branch. It’s doesn’t work for me: no signal on boot, and this after hdmi reconnect.
P.S. my TV is 1080p.
if anyone wants to test, i have created a branch where all (wifi,poweroff,hdmiv1+fbdev) is merged together (don’t want to merge to main-branch, because i have not tested much):
and uploaded to my gdrive https://drive.google.com/open?id=1MY8owoBdyv060u0QcE0GVC1YEtIPgu5E
hdmi, wifi and poweroff seem to work on a quick test 
please give response if it works for you or if you have any issues
